Bruteforce dm-crypt using dictionary

for a in {p,P}{a,A,4}{s,S,5}{s,S,5}; do echo $a|cryptsetup luksOpen /dev/sda5 $a && echo KEY FOUND: $a; done

This is sample output - yours may be different.

Given a file path, unplug the USB device on which the file is located (the file must be on an USB device !)

You have an external USB drive or key.

Apply this command (using the file path of anything on your device) and it will simulate the unplug of this device.

If you just want the port, just type :

echo $(sudo lshw -businfo | grep -B 1 -m 1 $(df "/path/to/file" | tail -1 | awk '{print $1}' | cut -c 6-8) | head -n 1 | awk '{print $1}' | cut -c 5- | tr ":" "-")

Prints out an ascii chart using builtin bash! Then formats using cat -t and column.

The best part is:

I tried a few curses based mp3 players for playing back choir practice songs for my wife.

Unfortunately none of the ones I tried were capable of scrubbing a track.

This uses bash only. ${#i} is the number of characters in variable i.

Generate a one-time TOTP token, then restore the clipboard after 3 seconds

Typing a word in terminal is easier than digging your phone out, opening your two-factor authentication app and typing the code in manually.

This alias copies the one-time code to your clipboard for 3 seconds (long enough to paste it into a web form), then restores whatever was on the clipboard beforehand.

This command works on Mac. Replace pbpaste/pbcopy with your distribution's versions.

Recompress all files in current directory from gzip to bzip2

- recompresses all gz files to bz2 files from this point and below in the directory tree

- output shows the size of the original file, and the size of the new file. Useful.

- conceptually easier to understand than playing tricks with awk and sed.

- don't like output? Use the following line:

for gz in `find . -type f -name '*.gz' -print`; do f=`basename $gz .gz` && d=`dirname $gz` && gunzip -c $gz | bzip2 - -c > $d/$f.bz2 && rm -f $gz ; done
