rewriting the regexp to not be dependent on Perl's non-greedy syntax is
quite simple. the bash-only solution below is a bit roundabout since
there is no substitute function for regular expressions, so we have to
extract the actual plain strings using the =~ operator and then do text

    printf -v ansi_color_re '\033\\[[^@-~]*[@-~]'
    while [[ "$path" =~ $ansi_color_re ]]

(note, I changed the [ after ESC to be mandatory, I think that is more

alternatively, you can write it using GNU sed like this:

    path=$(echo "$matches" | sed 's/\o033\[[^@-~]*[@-~]//g'

or more portably:

    printf -v ESC '\033'
    path=$(echo "$matches" | sed s/${ESC}'\[[^@-~]*[@-~]//g'
