Can't this be done without using any subsidiary commands?
Something like the following untested code. This removes all relative
names from PATH, not just '.'.
saved_IFS=$IFS
IFS=:
new_PATH=
for dir in $PATH; do
case $dir in
/*) new_PATH=$new_PATH${new_PATH:-:}$dir;;
esac
done
IFS=$saved_IFS
PATH=$new_PATH
