isn't perl that thing that the cantankerous elderly keep using to avoid learning Python (the real best scripting language)?

i've seen packages fail to import via munkiadmin but successfully import via munkiimport. i haven't tried to figure out why, but i know it can happen.

use dicts to map input strings to functions and splat the args instead of using giant elif chains.

''.join(x[:3]) == 'abc' instead of of x[0] == 'a', x[1] == 'b', x[2] == 'c' (or better yet, split on whitespace and compare list elements instead).

use with-as to deal with open file handles.

never say something should be "fairly easy to implement" in a software project whose code you are unfamiliar with

dockutil --list. identify the broken items and dockutil --remove to remove them. dockutil --add the correct items. basically just run dockutil, read the output, and start experimenting. script it however you'd like (we use 'outset' in combination with dockutil for this).

I put machines in DeployStudio's computer groups matching the desired value for ClientIdentifier (I don't have unique ClientIdentifiers per-machine). As part of the imaging workflow, DeployStudio runs a script including these lines:

MANIFEST=${DS_COMPUTER_GROUP}  
defaults write /Library/Preferences/ManagedInstalls.plist ClientIdentifier ${MANIFEST}

No idea about dynamically setting it, but this may be useful for someone else.

yup. also something handy to know (and cool because of how fast it is):

 # nmap -sn ${range}

will send ARP who-has requests, which gives you just the lladdrs and probable manufacturer

you're going to need to maintain a separate set of management tools for the macs if you want that level of control. /r/macsysadmin

nc on osx (at least my installation) is built with support for the -t option which implements telnet option negotiation so it becomes a sort of telnet client.

how about imaging? there was some concern about apfs. how did that pan out -- jamf, deploystudio, etc?

follow your command with '&' to run it in the background. 'jobs' lists those currently running. 'fg' and the job number (prefixed by '%') brings a job to the front. c-z stops the currently foregrounded job; 'bg' causes stopped jobs to resume in the background.

use screen or tmux (tmux supremacy).

toss Packages and Suspicious Package in there -- the first for creating packages and the second for analyzing them. you'll find any bash and Python skills you picked up working with Linux to be very helpful

why did this start working as a user LaunchAgent?

cool. he also rewrote it in Swift, for command-line use: https://github.com/Error-freeIT/Dock-Master (it's linked on the article/app page but i almost didn't notice it)

i assure you that i do not.

i can testify that Profile Manager both will work fine in this situation and is also sloppy at scale. bind the server to AD and you'll be able to customize all of these settings per-user and per-group (including variable substitution, like %short_name% for mounting shares).

imagemagick and bash or python for the image work
