I was watching your video on secure scripting and was interested in your no path script in zet 20220109171814

There is a issue with the script in that you cannot pass arguments to the target script executed

To fix shift the ARGV stack down and add $@ to the exec which will also need the quotes removing to stop exec getting confused

#!/bin/sh
cmd='which $1'
export PATH=
shift
exec $cmd $@

Note replace the ' with a backquote (iPhone keyboard has no backtick

Also the script on the video said which $2 rather than which $1
