Generate random passwords in shell with one special character
#! /bin/bashchars='@#$%&_+='{ </dev/urandom LC_ALL=C grep -ao '[A-Za-z0-9]' \ | head -n$((RANDOM % 8 + 9)) echo ${chars:$((RANDOM % ${#chars})):1} # Random special char.} \ | shuf \ | tr -d '\n'LC_ALL=Cprevents characters like ř from appearing.grep -ooutputs just the matching substring, i.e. a single character.shufshuffles the lines. I originally usedsort -R, but it kept the same characters together (ff1@22MvbcAA).
