I’m flattered
Here's a function you can use to generate a strong printable password on the fly: function gen_passwd () { openssl rand 150 |\ tr -dc '[:graph:]' |\ cut -c 1-${1:-13} } The default password length is 13 characters but you can pass a different length parameter instead. Explanation: * generate 150 pseudo-random bytes using openssl's rand * discard non-printable characters * cut to desired length Note that it will only…
Not as fancy as other tips here, but I bet this is really time saving in the long run for most developers. My core work is alway around ~10 directories, which are mostly code packages. As soon as I start working on a project/team, I create aliases for directories. They take the form: alias agg="cd /ws/ProjectName/src/PackageName/ && echo -n -e '\033]0;PackageName\007' && tab-color-devil-blue" The first part of course…
In my previous setup, I had a function that displayed a menu when I started bash, listing all my "main" directories. So each time you started a session you just had to press 1-7 to go where you wanted.

Damn! My work machine is cut off from outside networks and restricted to the versions of packages on their repo. Guess I can't use it. :/
My favorite new one that I have been using a lot: function cheat() { curl cht.sh/$1 } It queries the cht.sh cheatsheet of various Unix commands. 'cheat tar' prints: # To extract an uncompressed archive: tar -xvf /path/to/foo.tar # To create an uncompressed archive: tar -cvf /path/to/foo.tar /path/to/foo/ # To extract a .gz archive: tar -xzvf /path/to/foo.tgz # To create a .gz archive: tar -czvf /path/to/foo.tgz /path…
if [ ! -s "${cache_dir}"/"$1" ] ; then ...I use prefix qq for my commands because: 1. It is easy to discover all customizations via autocomplete 2. It is not going to clash with existing functionality # (Sort stuff by size, latest down, in a directory) alias qqsize="ls -lSrh" alias qqdate="ls -lrt" # First 100 of largest files/directories in a folder function qqlargest_files_100(){ du -a ./ | sort -n -r | head -n 100 } # Archivate item qq-tar-gz-it () { tar…
function qq-tar-gz-it () { tar -zcvf ${1}.tar.gz $1; }
Saves a step.
One I have been using for over 20 years, aliasing l to my favorite ls switches: alias l='ls -GFla'
I use these 3
alias ls='ls --color=auto --group-directories-first' # override
alias l='ls -hF'
alias ll='ls -hAlF'
alias lt='ls -clthF'
alias c='clear'
recent = for-each-ref --count=25 --sort=-committerdate refs/heads/ --format="%(refname:short)"
alias co='select br in $(git recent); do git co $br; break; done'
alias coo='select br in $(git br -r|grep -v "("|grep -v HEAD|cut -c3-|sed "s/^origin.//"); do git co $br; break; done'
