Linux

These aliases for zsh I use all the time. It's part of the prezto configuration framework.

setopt AUTO_CD              # Auto changes to a directory without typing cd.
setopt AUTO_PUSHD           # Push the old directory onto the stack on cd.
setopt PUSHD_IGNORE_DUPS    # Do not store duplicates in the stack.
setopt PUSHD_SILENT         # Do not print the directory stack after pushd or popd.
setopt PUSHD_TO_HOME        # Push to home directory when no argument is given.

alias d='dirs -v'
for index ({1..9}) alias "$index"="cd +${index}"; unset index

Type d and enter to list all the directories you've recently been in, then type the number at the start of the line followed by enter to immediately cd there.

Not sure if latest bash can do it the same thing, but some years ago I wrote a script to implement it there too. IIRC it might've been the automatic removal of duplicates in dir history that was missing.

Various uses of "find" in particular. "xargs" sometimes too. The capabilities of "bash" in general including scripting and the whole redirection, piping, and multiprocessing capabilities in particular.

Journalctl | grep -C 10 'foo' was useful for me when I needed to troubleshoot some fstab mount fuckery on boot.

Ha! Remember back when there was no fstab fuckery? Good times. But you have a massive init blob slowly eating other services and replacing them with shitty replicants like this embarrassment (ohai root NFS) and all of us Unix people are chuckling in our reduced-fuckery 'hell'.

xrandr --output eDP-1 --gamma .7:.7:.7

ps -ef | grep <process_name

Kill -9 proces id

I googled that -15 is better, I forgot what -9 even did, been using it for years.

A couple I use (concept of not exact), that I haven't seen in the thread yet:

Using grep as diff: grep -Fxnvf orig.file copy.file

Using xargs -

xargs reads items from the standard input, delimited by blanks (which can be protected with double or single quotes or a backslash) or newlines, and executes the command (default is /bin/echo) one or more times with any initial-arguments followed by items read from standard input.

EG: $ find ~/Pictures -name "*.png" -type f -print0 | xargs -0 tar -cvzf images.tar.gz

I like emerge --moo, just to See how larry is doing. Only gentoo tho :(

There are a lot of great commands in here, so here are my favorites that I haven't seen yet:

• crontab -e
• && and || operators
• ">" and >> chevrons and input/output redirection
• for loops, while/if/then/else
• Basic scripts
• Stdin vs stdout vs /dev/null

Need to push a file out to a couple dozen workstations and then install it?

for i in $(cat /tmp/wks.txt); do echo $i; rsync -azvP /tmp/file $i:/opt/dir/; ssh -qo Connect timeout=5 $i "touch /dev/pee/pee"; done

Or script it using if else statements where you pull info from remote machines to see if an update is needed and then push the update if it's out of date. And if it's in a script file then you don't have search through days of old history commands to find that one function.

Or just throw that script into crontab and automate it entirely.

Running Wine is the command I've used the most probs, you can tell I haven't touched the thing in months.
