rm: it is dangerous to operate recursively on '/'
rm: use --no-preserve-root to override this failsafe

>>846127

Find duplicate files , compare md5sums and move the duplicate?

>>846123

rm -rf /

>>846140

First one lists all duplicates starting in the working directory, and nothing more.

The second one renames all files to their sha256sums, but only keeps the last extension (so .tar.xz would become .xz)

Only if you install with UEFI comparability. Also, what does systemd, an init system, have anything to do with BIO/UEFI, grub and efi partitions? Nothing. You can install gentoo with UEFI and without systemd and still be able to do this.

So what? All people make mistakes and sometimes blunders too.

>>846995

They do that consistently. "Command" is a homonym. "find" is a command. You're just being incorrectly pedantic.

good work, pajeet

These aren't really bestest, but I find them to be useful.

Recursive convert audio

find . -type f -name "*.flac" -print0 | while read -d '' -r in; do opusenc --comp 10 --bitrate 64 "$in" "${in%.flac}".opus; done

Recursive find and optimize images

find . -type f -name "*.jpg" -exec jpegoptim {} \;

find . -type f -name "*.png" -exec optipng {} \;

Unzip folder of zip files into their own directory

for f in *.zip; do unzip -d "${f%*.zip}" "$f"; done

Zip directories into their own zip file

for i in *; do zip -r "${i%}.zip" "$i"; done

Recursive find and remove by extension

find . -type f -name "*.XXX" -exec rm "{}" \;

Still image with audio webm for chans

>fork bomb

holy shit that's funny i just ssh'd into my mom's raspberg pi and put that shit into a bunch of her startup scripts.

>>847269

That's disgusting. Use grep -c. Use functions. Put it in a separate file, on multiple lines.

I'm a bashlet but I needed a pkill command who sends SIGKILLs instead of SIGTERMs for when I try to make music with jackd, so I made one with pgrep.

This line will install it in $HOME/bin/, you can pass options to pgrep, and it also gives you the list of processes which have been killed.

printf '#!/bin/sh\nfor pid in $(pgrep "$@"); do kill -9 $pid; done\nuntil [ $# -eq 1 ]; do shift; done\nps -A | grep $1' > $HOME/bin/pkill9 && chmod 755 $HOME/bin/pkill9

>>847806

"pkill -9" or "pkill --signal KILL".

Read the man page.

>>847514

Why would you do that?

>>847871

Damn. I vaguely remember trying to use pkill -9 years ago and it wouldn't work the way I expected, so I thought it was a good idea to write this.

Well, I learned things about Unix at least.

>>847873

because she still won't change the default password 'raspberry' even though i showed her that it's extremely vulnerable. she just acted bitchy when i showed her. she said "I don't have a password on my pi" i'm guessing she thinks that because theres no login screen.

>>848755

Rape her.

>>846987

$ mv /usr/bin/find /usr/bin/nigger

Same program, different command. Ergo 'find' is a command. QED
