Unfortunately, the 'where' program is a csh/tcsh builtin, and isn't available on other shells.

How do you implement this in Bash/etal?

type -a <program>
function where() { perl -MFile::Which=where -e 'print map {"$_\n"} where shift' $1; }
# use tcsh's builtin from Bash function where() { WHERE=$1 tcsh -c 'where "$WHERE"'; }
