Wasn’t trying to be a prick- i was commenting “here’s what I’m seeing with your proposal and the presented obstacles, how would you overcome them?”
One approach could be something like “set -x” after setting a confirmation with “trap” command.
confirm_execution() {
echo -n "Execute $BASH_COMMAND? [y/N] "
read response
if [[ $response != [yY] ]]; then
echo "Skipped."
return 1
fi
}
trap 'confirm_execution' DEBUG
set -x
user_command
set +x
But that’s a wrapper script
