inspect and modify command line parameters in a bash wrapper script

wrapper.sh

#!/bin/bash

c=0;
args=( "$@" );
while test $c -lt ${#args[@]}; do
        # inspect "${args[$c]}" 
        # assign to args[$c] 
        c=$(expr $c + 1);
done
set -- "${args[@]}";
# if you want to add new args:
# set -- "-u" "user" "-p" "pass" "${args[@]}";

# run original command with $*, e.g.
# exec yt-dlp "$*";

# and invoke this script with command line 
# flags as if it were the original command.
