Elisp and Bash are not close so one might as well start
over ...

If you insist, here are some zsh for you to practice on.

So tell me, what's the Elisp equivalent of:

#! /bin/zsh

create-100-meg-bogus-file () {
    local file=${}
    rm $file
    dd if=/dev/urandom         \
       of=$file                \
       count=$(( 1024 * 100 )) \
       bs=1024 | sha256sum | ( read rnd _; echo $rnd >> $file )


#! /bin/zsh

t () {
    # check number of arguments
    if [[ $# == 0 ]]; then
        echo "syntax: $0 COMMAND" >&2

    local cmd=$1

    find-zsh-command $cmd

    # use whence; if a path, do 'ls'
    local whence_hits
    whence_hits=("${(@f)$(whence -ca $cmd | sed "s#$HOME#~#g")}")
    local  h
    for h in $whence_hits; do
        echo $h
        ls -Ghl --color=auto $h 2> /dev/null
        if [ -h $h ]; then
            local dest=$(readlink -e $h)
            set-fg-color 3
            echo -n " * links to: "
            echo -n $dest '\n             '
            ls -Ghl --color=auto $dest

    # if a script, output it
    cats $cmd


The whole file (323 lines)

After that only ~99 more and you are all set :)
