Please use a less potential harmful target script as an example

[henrik-jensen]

Thanks for the guide, I'm really grateful.
But could I suggest to you to change the dummy script to something maybe less potential harmful, for example:

if [ -z "$1" ]; then
  echo "No command number passed"
  exit 2
fi

exists=$(fc -l -1000 | grep ^$1 -- 2>/dev/null)

if [ -n "$exists" ]; then
  echo "This would have been executing the command:"
  echo fc -s -- "$1"
else
  echo "Command with number $1 was not found in recent history"
  exit 2
fi

Ran the history command to see what was in there and thought,- ups dothis could also work as an effective foot amputation device if entering the wrong number. 😲😀
