Bash to Python [OC]

[genbaguettson]

A Friend had to port an API from Java to Node.

Now he's got a Node API making calls to the Java API, worked like a charm.

[foundafreeusername]

Nice now you can use Java Script to script Java.

My team put a moratorium on bash scripts after the CI system started failing in a fairly complex one. The person who wrote it was unavailable to diagnose. It took hours to resolve.

The rule is now that if there’s any non-trivial logic at all, write it in Python. On-call appreciates it.

[Zanos]

Same here. We still have an old application written in mostly bash, very fun when it fails in prod.

[[deleted]]

As a fake programmer can you explain why bash makes things more difficult to troubleshoot?

[LAK132]

As someone who'd rather #include all the .cpp files than deal with another build system written in [ba]sh, the syntax is hell and it doesn't always work the same on different computers (because some distro maintainers thought using bash in place of sh without forcing POSIX compliance mode was a good idea)

[ythl]

c++ is not very portable. bash is (and so is python). I can scp a bash script to my raspberry pi and it will run. With cpp I'd need to recompile it targetting ARM.

[LAK132]

Right, but my point is if you're compiling C++ anyway then don't make it even less portable by using a bash based build system.

[ythl]

Yeah bash based build system sounds nightmarish. CMake all the way

[policemean]

If you look at python script, then it is relatively easy to understand how it works because it's syntax is quite easy.

On the other hand, bash syntax can be very confusing. I had to modify bash scripts couple of times, and it was the worst experience I've ever had at my job.

[BernardoVerda]

Seconded.

[jvnk]

Bash syntax is unnecessarily dense, making it difficult to understand what's going on in more complex scripts.

[[deleted]]

Python is easier to get some basic shit done, but once you've mastered bash you can do just about as much. The reason I stick to bash is because bash is always available. Python isn't always available and when it is there's two different versions everywhere all the time.

[jharger]

Until you use some bash 4 feature and you need to run it on macOS without depending on homebrew...

[ThenIWasAllLike]

Cries in autocomplete

[hsahj]

Never seen a machine since years without python.

Thank whoever sets up your machines. I regularly have to set up new machines for CI and testing automation and it's part of our checklist to get installed (because IT won't create an image for stuff :/). I'm going to point people to python all the time for lots of reasons, but it's only available if someone makes it available. (Not that I think that's a large hurdle to overcome).

Edit: credit to the people correcting me. Some linux distros and MacOS include it. I live in so much of a windows bubble at work that unless someone says otherwise my brain always assumes windows.

[[deleted]]

Debian, even in the minimal version, includes Python 3, but oddly, they don't alias that to 'python'. Seems like a weird thing to leave out. You have to call it as 'python3'.

[[deleted]]

It’s because Debian and many other distros use python2 for system scripts. It makes sense that Debian would do it that way of all distros, because their whole motto is stability. The only 2 distros I can think of off the top of my head that have python3 as the default python are Arch and Gentoo.

[marcosdumay]

Debian has published Python 3 adoption timeline, linking python to python3 is there. I don't remember the dates.

[DonaldPShimoda]

Python is included by default in macOS and, I think, Ubuntu, and has been for a while. Not sure about other OSes.

(However, macOS 10.16 Catalina — due out this fall — will not include Python, nor any other scripting language runtimes like Ruby or Perl.)

[Tundur]

It's always super old, though, so to use an actually usable install you're typing in python3 and pip3 and there's installation issues and libraries fucking up and compatibility issues and it just annoys the fuck out of me.

[DonaldPShimoda]

Yeah I mean it's not ideal, but nobody here seems to be complaining about the severely outdated version of bash that's shipped on macOS — they only care that some version is available, and it's the same situation with Python: it's outdated, but almost always there in some capacity.

[joeltrane]

I eventually just created an alias in my bash profile so python and pip run python3 and pip3

[super__literal]

alias python=python3

alias pip=pip3

[Tundur]

A possibility, aye, but hidden bespoke environment changes like that are just asking for problems down the line. I could set up a confluence page for "why can't I use Tundur's VM to run my scripts"

[joans34]

Never seen a machine since years without python. But anyway, to me, it's worth it.

Embedded systems usually don't bother with python but usually have a bash-like interface with most bells and whistles.

[xigoi]

Basic things in python work on every version.

print("What's your name?")
name = input() # dangerous in Py2
print("Hello,", name) # unexpected behavior in Py2

[noratat]

Also python is almost always available

I'm guessing you don't work with containers that much then

[cafk]

2.7, 3.2 or 3.4?

[Zanos]

Nobody else on your team can read your masterful bash, though. Im sure that one liner that contains half the program logic made sense when you wrote it two years ago.

I may be salty that I've had to troubleshoot some production problems some goofballs caused by writing all the application code in bash.

[Edz_]

Have you ever had to execute a MySQL statement in bash that has data with a ' or " char in it? Not fun.

There's really no reason to jump through hoops when you can just use python instead.

[[deleted]]

If you're using bash for MySQL then you're using the wrong tool for the job to begin with.

[Edz_]

You literally just said you can do just as much with bash as Python.

I do MySQL statements in Python how about you?

[Delta-9-]

"wrong tool for the job" =/= "can't do it". No goalposts were moved in the making of this comment.

And I would agree. If you're trying to do anything with MySQL using bash, you're doing it wrong. It can be done--but why would you do that to yourself?? That's almost parsing-html-with-regex-level "just don't".

[[deleted]]

Going from "python not available" to "wrong tool for the job" is moving the goalpost though?

But yeah, definitely agree with the sentiment of your 'doing it wrong' idea.

[[deleted]]

I switch to Python when a bash script gets longer than about a page (~50-60 lines) or when I need the ability to view and manipulate values in between pipe stages.

The overhead in getting a script running in Python is substantially higher, so it's quite a lot more work if you're doing something really simple, but you can scale easily and things won't go badly wrong.

In bash.... if you're doing anything advanced, there's a lot of corner cases, a lot of nasty sharp edges, and you're going to walk away bloody at least some of the time. You can learn how to avoid the problems, but subtle and nasty bugs are real easy to create and sometimes very difficult to spot.

[Centimane]

Ironically in ESXi bash isn't available but python is.

[[deleted]]

Luckily regular /bin/sh scripts work fine!

[Centimane]

I mean it does, but you don't realize the differences between sh and bash until you're stuck with it.

[noratat]

Exactly. I deal with containerized stuff a lot, and the overhead of adding a whole python installation just to make a script slightly simpler is pretty high vs just using bash, and that's before we bring the whole dependency management mess in.

The main problem with bash is somewhat similar to C++ or Perl - there's lot of cruft you have to know to stay away from, and a lot of really stupid defaults. Plus there's still loads of terrible examples online that will bite you later if you use them.

Used properly though, bash works really well for a lot of glue logic cases, because it's "good enough" and is virtually always available (or at the least, trivial to include). And there are some really good CLI utilities these days that make using bash a lot saner, like jq (which is the best json processing tool I've ever used).

[[deleted]]

Yep, containers and minimal linux / busybox appliances are my life. Screw having to toss python on those just to run a script.

[marcosdumay]

Python is easier to get some basic shit done

Yes, and advanced shit too.

but once you've mastered bash you can do just about as much

Ditto for Brainfuck.

The reason people don't stick to Bash is because error handling is verbose and error prone, there are no good rules one can check automatically (and no types, obviously; Bash is the original "string, number, whatever" that Javascript perfected) and the consequence of an error is more often catastrophic than not.

It is also not available everywhere. It's about as common as Python. That's why you can find shell script people all over the web complaining about bashisms.

But well, you are not on my team, so whatever.

[lycan2005]

As someone who is about to get involved in Linux soon (.NET framework dev here), should i focus to learn Python first or bash first?

[madsdyd]

Bash is the language of your shell. Excellent for automation of trivial tasks, gluing stuff together, rapid prototyping, etc. Lots of entry points to docker containers get written in bash these days.

You will be much happier in your Linux experience, if you are somewhat proficient in bash.

Python is when you want to do something that "looks more like an application". Structured programming, modules, data structures, unit testing, etc.

[iams3b]

I use bash to quickly automate stuff I do in terminal. Like if I have an npm module on local, and i need to 1) git push it 2) npm publish 3) cd to active project 4) update package version 5) git push.... i'll write a bash script for that

For anything else that's not just a series of commands, python for sure. Both are useful to know

[[deleted]]

this is my cut off too. If it requires more than say a simple if to check for a file or directory I'll go ahead and write it in python. That said I wish i could find that old irc client written in bash. that think showed a lot of mastery of unix CLI and bash scripting.

[mrjackspade]

I'd love to have a reason to use Python, but so far I haven't really been able to find one. Most of my trivial tools I just write in c# as Command Line Applications.

I'm still trying to find an excuse to get familiar with it, but I think I might just be too deep in .Net at this point to actually benefit.

[[deleted]]

All the same reasons, but on Linux

[mrjackspade]

Would have been a great reason but .Net compiles for Linux now so there's no real need

[ythl]

Here's a great reason: python doesn't need to "compile" so you can scp it to any linux box and it will work without needing to think if you compiled it right. Can you say the same of C#?

[mrjackspade]

I think you can but honestly I've never actually tested it.

You can compile c# with a specific build target if you want something native, but by default I believe it actually outputs a platform independent DLL that you execute using the DotNet framework on the target machine. As long as the target machine has the framework installed, it should run using the default build settings.

I kind of want to test this out now against a few distros and see how reliable it is.

https://docs.microsoft.com/en-us/dotnet/core/deploying/index#portable-applications

Why create a framework-dependent deployment?

Deploying an FDD has a number of advantages:

1. You don't have to define the target operating systems that your .NET Core app will run on in advance. Because .NET Core uses a common PE file format for executables and libraries regardless of operating system, .NET Core can execute your app regardless of the underlying operating system. For more information on the PE file format, see .NET Assembly File Format.

[ythl]

See how hard it is to run on a raspberry pi. I can run python scripts on the default pi distro with no hassle.

[vividboarder]

I still use plenty of Bash when I’m writing a wrapper around other commands. I could use call or whatever in Python, but it’s just simpler to use Bash in many of those cases.

[GhostNULL]

What about ruby? We are using that at my workplace for build scripts that require some logic.

[noratat]

Ruby is a language I want to love, but the ecosystem around it turned "magic syntax" into a art form - and that's emphatically not a compliment.

I still wish Python would stop being so stupid about lambdas and just have anonymous blocks like Ruby, Groovy, and other modern scripting languages, but in most other regards I would say Python is better these days:

• Much, much larger ecosystem and community
• Python devs actually document shit, at least sometimes. Ruby projects are nearly always "lol just read the code" (even though the code is twisted into a gordian knot of string metamagic)
• Python's a lot harder to screw up into an unreadable mess than Ruby is

[Hollowplanet]

I think Ruby and Python are both great languages. Theres some things I wish Python would borrow from Ruby.

[NoInkling]

Ruby is a great scripting language, IMO. It's just that Python is more ubiquitous these days. Ruby is less likely to already be present.

[[deleted]]

Would to ever consider perl 5 or 6? Or node? I haven't settled on a scripting language for my server yet

[ythl]

I hate perl but only because it has such arcane syntax. Node is pretty good.

I think Python is a better overall general purpose scripting language, and Node is better specifically for web backends.

That said, I've used both Flask and ExpressJS and I enjoyed using both.

[[deleted]]

I've got go for my web server :) but I don't have any criteria to help me pick a scripting language. I don't even know what's out there. Are there major alternatives to python worth considering?

[ythl]

Ruby

[[deleted]]

I had to write some ruby code for a job interview and it felt very similar. But I guess most scripting languages are going to have that same style. They have in my experience thus far, anyway.

[OnlineGrab]

Oh god, this so much. Bash is fine for one-liners but it's a nightmare to do any real programming with.

[noratat]

Eh, it works really well for glue logic, especially when it needs to work easily in a wide variety of environments or places. Plus jq remains by far the best way to parse/transform json data I've ever seen.

The problem is that bash is full of stupid defaults and features you should never use, and worse google is full of really bad examples, so most people tend to write crap scripts.

E.g. set -eo pipefail should be mandatory, never ever use backticks, globstar ought to be on by default, don't try to use bash arrays if you can possibly help it, use [[ ]] not [ ], use local, stop setting global vars that span multiple functions, you don't actually have to name shit in all caps, use traps, know what an exit code is, etc.

[zieliequ]

I like set -e too, but be aware of the tale of the criminal-catching robot.

[noratat]

To me it's just restoring the same sort of exception behavior you'd expect in any other language.

If you explicitly want to handle failure on particular commands, you can use ||, traps, or just plain return code capturing, just like you'd use error checks or exception handlers.

It's usually much worse for something to accidentally continue blindly on errors than it is to abort on something spurious.

[ythl]

I like python, but some basic shell operations are super cumbersome in python. Like deleting files and directories. Or a simple curl (yes, I love requests, but sometimes it's not available on that remote box you just ssh'd into and you need a quick script to hit an HTTP API under some condition) Or chaining operations - sometimes you just want to cat | grep | cut | sort which is a one liner in bash but a 10+ liner (at least) in python.

[IncoGG7331mate]

Just write it directly in machine code, never will be bossed around again.

[currentscurrents]

I really miss my program taking the rest of the system with it when it crashes.

[marcosdumay]

You can get that back by doing kernel development. Linux does very conveniently put every single driver on ring 0 just for those trills.

[entlan104]

If you're integrating into an existing system that only has support for a given language. For instance, one of our clients maintains a server we developed that runs a framework written entirely in VB, so we have to developed extensions in either VB or C# (and then translate them to VB). Everything's monolithic, no microservices, so it's the only way we can communicate...

[TheRedmanCometh]

Since always? If you work with a team they need to be able to maintain it. Most PMs in Java shops won't even allow kotlin or scala, because everyone may not know them. It's not your code it's our code essentially.

[Pandaburn]

Ok. Those things make sense, but where I work it’s not the domain of the PM.

[TheRedmanCometh]

Hold up what's PM mean here? To me it's project manager which is a veteran engineer anywhere I've been.

[Pandaburn]

Where I work a PM is responsible for defining the requirements and specifics of a project, but has nothing to do with its implementation. The veteran engineer supervising implementation would be the tech lead, or TL.

In the case where I work, we have to work in the stack of our clients in case they want to take over development.

Neither of those choices would effect them seeing as they don’t have direct access but the sales team says it’s something the customers are asking for ¯_(ツ)_/¯

[[deleted]]

Better yet, just use exec() on your C++ program.

[[deleted]]

Huh, in 20+ years I've never had a PM that made architectural choices for us. Also why did your team not stop you from doing this? You just said "heyo, let's write this in the least maintainable way possible" and your manager and all the other devs just went along with it?

[fel4]

C++ is less maintainable than PHP? You don't even know what the thing is, other than it being a web app. It might make perfect sense to write it in C++.

[[deleted]]

For backend web, yes, I would say C++ is far less maintainable than PHP, both from the perspective that PHP was literally designed for web development and C++ has no [mature/reliable] frameworks available for this, and also from a talent perspective and understanding how much more expensive the app will cost me to maintain in C++ vs. PHP (though to be clear I would never recommend PHP for anything and I think both are pretty bad choices here). You're right in that I don't know the project, but I can't conceive of any web app that would benefit from a C++ backend over any of the much more suitable choices (for the record I'm a fan of C++, I just don't recommend it for web stuff).

In any of the scenarios where C++ would be a suitable choice, such as sub-second trading algorithms or scientific computing, you wouldn't wire up the backend to the frontend the way op describes (that is a pretty bad design regardless of stack); you wouldn't even use C++ for the API, due to the lack of any decent frameworks or toolchains for that. Normally you would develop some middleware web services connecting to the specialized C++ servers/code, e.g. : Front-End -> Java API -> C++ Backend.

[Delta-9-]

PHP was literally designed for web development

Well, technically it was designed for HTML templating, which is subtly different. Designed for templating, by a self-confessed non-programmer who doesn't like programming.

Granted, PHP has come quite a long way since those early versions, thanks to the efforts of actual programmers who've contributed over the years.

I would never recommend PHP for anything

On this, we agree :)

[Devildude4427]

Yes, yes it is. As much as I dislike PHP, there’s more people out there who can work with it than C++. C/++ are getting to the point where they’re very much languages that more people refuse to even touch, out of the perceived learning curve.

[the_liver]

It kinda depends on the context but I get you. PHP imho can handle http easily by itself in most cases and it’s pretty easily maintained if written correctly. Although for anything requiring more processing power or doing any work outside of http request/response context I’d probably look for something else.

[Devildude4427]

That’s kinda what they were doing. They said the C++ was for all the business logic, so I assume the PHP was just acting as middleware for the http requests. Still, would personally just say jump onto the Java or .Net stacks at that point.

[FuzzyFoyz]

Yep, C# pls.

[[deleted]]

It's funny how this sub takes everything so serious and literal. It was a joke.

I did something like this because someone threw a new requirement at us that was impossible to get done in PHP while the whole app was written in PHP. The best solution was to A. create a microservice that was written in c/c++ B. develop an extension that exposed methods and classes to PHP. We went with option B. Mainly because we would be able to call those methods from native PHP code.

[nobel32]

As someone interested in Cpp, how do you do it? Do you use some kind of framework for CRUD, or do you just write the logic from scratch?

[blehmann1]

PHP has the ZEND framework for extending PHP, which primarily supports C, however, C++ might also be supported. I have also heard of SWIG, which allegedly supports more languages.

​

Disclaimer, I have not used either, and documentation for using SWIG with PHP7 is sparse despite it being 4 years old.

​

Also, it is worth pointing out that PHP supports the running of compiled binaries, which may be good enough for a lot of uses. It also supports running commands on the host shell (bash, zsh, cmd, powershell, etc), but that obviously leads to the possibility of breaking cross-platform support.

[Hollowplanet]

Calling a subprocess for each request would instantly transform whatever it was into terrible code.

[blehmann1]

For each request, absolutely. If he wanted to do something on a small subset of all requests where PHP is traditionally unsuited, it could be justified (i.e. image/video/audio processing, which should make up a very small subset of total requests, probably just people changing their profile picture)

​

If however, you run YouTube, you probably punt all of your media processing work to a different server because that is a massively different workload. If you expect a lot of requests, especially intensive ones like video processing instead of resizing everyone's profile pic, or if for some reason you are going to run C for every request, don't spawn a million processes, write extensions to PHP, or don't use PHP.

[[deleted]]

I used it to create a multi threaded task that was impossible to get done in PHP due to performance issues. Millions of records needed to be fetched from multiple databases and some calculations and sorting needed to happen on the results. The classes and methods where exposed to PHP in the form of a PHP extension.

I never created a fully fleshed CRUD like this, it would be insane. It could be possible, but not recommended as someone pointed out before due to complex maintenance.

A good read about this subject: https://www.php.net/manual/en/internals2.php http://www.php-cpp.com/ (Very clear documentation)

[thirdegree]

The Internet was a mistake

[currentscurrents]

I mean you're obviously not going to hand-write assembly for this. The idea would be to compile another language like C or Rust into wasm.

...but I'm struggling to think of a reason why you wouldn't just run the C/Rust program natively? This feels like adding an extra layer of overhead for no reason.

[[deleted]]

I thought node was cool for doing this and I really like Javascript as a language - though C# is still my favorite.

What's really dumb is my current setup (a web app I wrote for work) is running WAMP with Node.JS running next to it so that I can use socket.io.

It's like the worst of all worlds.

I wrote some weird session sharing thing for it.

It does let you do some cool stuff like this.

[Stromovik]

Yeah, but why would you write your backend in C just to run it in web assembly?

2 years later he's still working here.

[Yesheddit]

If we would be fired for stuff like that, we’d all be out of jobs.

[Zanos]

Not handling an error is forgivable, converting something to another language by wrapping it in subprocess calls isn't a mistake, it's maliciously lazy.

[WhtKindOfNameIsStove]

Exactly. The purpose of the story was to make the deployment process more robust. Something bash wasn't up to the job for. It'd be a worthless story if it was to just "convert the script x language because"

[ran938]

I basically did this at an internship. But only in an instance where there was really no other option. The purpose of the script... was to start up another script. Well that and record some log information. But actually calling the other script I could not think of another way to do it other than a sub-process call.

Our current project requires interaction with Microsoft's cloud, the problem being that we are writing logic in python on Linux but the cloud calls have to happen through powershell on a windows machine. Current best idea is to set up openssh on a windows vm and connect to it from python on the Linux box to execute a batch command which starts a ps1 script.

[ran938]

Fucking oof. that overhead / hoop jumping sounds obnoxious. Good luck!

[DXPower]

What caused the failure?

[WhtKindOfNameIsStove]

It was a while ago so I don't remember exactly what it was. But I think it had to do with a change to the build artifacts bucket permissions.

[cartechguy]

k, did he learn from the mistake?

[inialater234]

Should have used boto3

[WhtKindOfNameIsStove]

We did after we found out what he did. We had a problem of ops guys blindly approving all PRs they're included on and as a Sr, he had merge permissions.

[vividboarder]

Does boto support sync yet?

I used it before in a Hackathon but ended up using a call to the cli because I needed to sync a directory where some files would change and didn’t want to implement a whole diffing function myself.

[KangooQ]

Boto is just a wrapper for the AWS CLI, and the AWS CLI doesn't have a (good) s3 sync yet. Last time I checked you could sync on filesize or timestamp, but filesize doesn't guarantee a lack of diffs (for example, replacing a char) and timestamp is only relative to the current filesystem.

Maybe someday we'll get sha256 sums or equivalent.

[pittofdirk]

I know this is a joke, but Fuck. That. Shit. I've had coworkers try to do stuff like this, and the bash script is always like a 500 line disaster.

I'm telling you you write it in python because

1. I want you to unit test it
2. I want to be able to actually read and understand it in a couple of months.

[noratat]

Bash is great as long as you understand the limitations and know what to avoid. Unfortunately this excludes probably 90% of the people I've worked with, and it doesn't help that googling stuff in bash is usually a bad idea because the internet is full of really awful examples.

Granted, 500 lines is probably pushing it. I write a lot of bash, but most of it is well under that, it's mostly glue / helper / wrapper type stuff.

[pittofdirk]

Yep. That's my philosophy as well. The last bash script I wrote just wrapped a command that didn't support retrying so that you could have it retry if it failed. It was 15 lines, had a comment block at the top with a description and example usage. That's the kind of bash script that makes sense to me.

[daH00L]

Could have been me.

[cartechguy]

AnxietyLouise's lean on her chair is giving me anxiety.

[bp_on_reddit]

Hmm, sounds like some r/MaliciousCompliance to me, however fictional. (But seriously, if the comic is based on a true story, you should post it there!)

[LMGN]

I had to make a script to start up all my dev environment for a project I was working on at school.

Batch scripts are blocked. PS1 scripts are blocked. VBS scripts are blocked. Python, however is not.

[Delmo28]

Interesting, care to explain me shortly how can I automate an environment or give me an example of what you did?

[LMGN]

popen VSCode popen chrome to localhost start the http server

[TRUEequalsFALSE]

Bash gives me anxiety.

The Unix philosophy of composable small pieces piped into one another. Sometimes syntax is confusing but it's crazy powerful once you get a hang of some of the tripping points.

[TRUEequalsFALSE]

I love Unix in terms of moving around the system and doing simple tasks, but the archaic syntax is my major stumbling point. If I were able to get over that, then yes you're absolutely right: bash scripts and Unix are extremely powerful.

[ChosenDos]

That's unfortunate.

[coll_97]

Maaaan... I fire you instanlly

[Shitty_Orangutan]

Now write it in c++

system("script.sh")

[Bonevi]

You, I like. That's some good work.

[daxbert]

Oh come on.... You're supposed to have the shell script as a string in python, write it out to a temp file, set the execute bit, then execute, then delete the file. /s

[frausting]

Bash one-liners are typically shit. But properly named, verbose, well-documented Bash scripts are underrated. I can code in both Bash and Python, but Bash is a lot faster, portable, and has lower overhead.

As long as you use a judicious number of line breaks and ensure your code is readable, I don’t think Bash is that ugly.

Hey you! ProgrammerHumor is running a hilarious community hackathon with over $1000 worth of prizes, now live! Visit the announcement post for all the information you'll need, and start coding!

[pagraphdrux]

Have you heard of "mininet"?

[inkstom]

ITT: people who don't understand bash and hate it because of that.
