I wrote a wrapper around which that would display the file and line number where a function was defined. Is there a way I can do the same for alias? Also, any comments or critiques on the code?

function where() {   cmd="$  1"   info=$  (command -V "$  cmd" | head -n 1)   #rc="$  PIPESTATUS[0]"    case $  info in     *function*)       extdebug=$  (shopt | grep -q extdebug)       ! ((extdebug)) && shopt -s extdebug       declare -F "$  cmd"       ! ((extdebug)) && shopt -u extdebug       ;;     *) echo "$  info" ;;   esac } 

Output looks like:

$   where ls ; where l ; where bad ; where where ls is /bin/ls l is aliased to `ls -Al --color=auto' bash: command: bad: not found  where 6 /home/harleypig/projects/dotfiles/.bash_sources.d/tools
