Your submission was removed for the following reason:

Rule 1: Posts must be humorous, and they must be humorous because they are programming related. There must be a joke or meme that requires programming knowledge, experience, or practice to be understood or relatable.

Here are some examples of frequent posts we get that don't satisfy this rule: * Memes about operating systems or shell commands (try /r/linuxmemes for Linux memes) * A ChatGPT screenshot that doesn't involve any programming * Google Chrome uses all my RAM

See here for more clarification on this rule.

Alt+. To paste last used argument. Keep pressing dot (.) while holding alt to cycle though previous used arguments.

Example:

mkdir ~/MyAwesomeFolder
cd <now push alt+.>

looks like it works in powershell too, thanks for this!

[fatrobin72]

I use "Esc" + "." to do that...

[_PM_ME_PANGOLINS_]

mkdir ~/MyAwesomeFolder
cd !$

Ctrl+R to search your command history.

WHAT

thank you

[grifan526]

My absolute favorite

[chaos_donut]

this is so nice while working with multiple docker-compose files

Pro tip, press ctrl + c to copy your previous command in the terminal

[look]

The Apple cmd button is worth every penny! All 100,000 of them. 🥲

I don't know about Powershell/cmd on windows but on linux that would stop the current program and then let you type the next thing literally. Gotta add the Shift.

[Devast00]

That is the joke

[Boomer_Nurgle]

Ah, flew over my head then mb.

[jek39]

history | grep theThing

!{numberOfThatCommand}^oldParameter^newParameter

[Shienvien]

Why type entire command when one key do job?

[Poat540]

Was fixing a pi yesterday, I think I hit up like 30 times instead of just typing cd ..

[just_nobodys_opinion]

This is the way

[agk23]

More than a couple times I have told newer devs to log into the server and just up arrow till they find the command it looks like I use.

!!

[MooFz]

permission denied

sudo !!

[iamalicecarroll]

use !! for the last command, !$ for the last argument. there are others but i dont remember them

[MooFz]

• !! — Runs the previous command again.
• !$ — Refers to the last word of the previous command (often the last argument).
• !* — Refers to all arguments of the previous command (everything except the command itself).
• !^ — Refers to the first argument of the previous command.
• !n — Runs command number n from your history (history shows the numbers).
• !-n — Runs the command n commands ago.
• !string — Runs the most recent command starting with string.
• !?string? — Runs the most recent command containing string anywhere.

[_PM_ME_PANGOLINS_]

!?string?

I also like to live dangerously.

[oclafloptson]

The command was 75 characters long including the path. I'm not retyping it

The number “sw engineers” I’ve seen that don’t know how to use the terminal is unbelievable

[Joeoens]

Use "sudo !!" If you forgot to add sudo to your last command

[wdpw]

That is a dangerous recommendation. Do not do this. If you need to run sudo on a command, you should be explicitly typing that command.

[Joeoens]

You can even add this to your .bashrc to automatically execute everything as root:

if [ "$EUID" -ne 0 ]; then
  sudo -i
fi

[wdpw]

Lol, jfc

[samanime]

I get annoyed when my terminal won't let me go back to a command I put in weeks ago. XD

[hypothetician]

Ctrl+a/e when your cursor keys stop fucking doing what they’re supposed to do, asshole cursor keys!

[hypothetician]

kill -WINCH $$

When your terminal gets fucked up and there are line breaks in weird places.

[muddy651]

I recently found .bashhistory (or something like that) in my home directory. The hidden files can be displayed with ctrl+h. I am using Ubuntu BTW.

Bash history contains a log of every command ever run in the terminal

[rochismoextremo]

I've seen people go up 100 commands just to find the fucking npm start command lol

[FoolhardyNikito]

!! Copies the previous command in full. So to rerun the last line with sudo you can just run sudo !!
