You mean like this?  :-)  [[been there, done that, long ago!  I have no
csh today!]]

#! /bin/sh
:

if [ "$1" = "-a" ] ; then
	#
	# We could search the PATH explicitly by individually setting
	# PATH to each of its components and then trying "type"....
	#
	echo "$(basename $0): -a not supported in this version" 1>&2
	exit 2
fi

# XXX this isn't a very true emulation since we explicitly ignore
# aliases and functions...
#
for prog
do
	# NOTE:  If this were a ksh script then it could just call "command -v"
	location=$(expr "$(type ${prog})" : '[^/]*\(.*\)$')
	if [ -n "${location}" ] ; then
		echo "${location}"
	fi
done

exit 0
