Linux

Here are probably the most useful ones. I prefer for rm to be interactive so I don't accidentally delete something important and for mkdir to create a parent directory if necessary.

alias rm='rm -i'
alias mkdir='mkdir -p'
alias podup='podman-compose down && podman-compose pull && podman-compose up -d'

This extract function (which I didn't make myself, I got it from when I was using nakeDeb) has been pretty useful too.

function extract()
{
     if [ -f $1 ] ; then
         case $1 in
             *.tar.bz2)   tar xvjf $1     ;;
             *.tar.gz)    tar xvzf $1     ;;
             *.bz2)       bunzip2 $1      ;;
             *.rar)       unrar x $1      ;;
             *.gz)        gunzip $1       ;;
             *.tar)       tar xvf $1      ;;
             *.tbz2)      tar xvjf $1     ;;
             *.tgz)       tar xvzf $1     ;;
             *.zip)       unzip $1        ;;
             *.Z)         uncompress $1   ;;
             *.7z)        7z x $1         ;;
             *.xz)        unxz $1         ;;
             *)           echo "'$1' cannot be extracted via >extract<" ;;
         esac
     else
         echo "'$1' is not a valid file"
     fi
}
