Those aren't OS delimiters. They are ANSI escape codes for displaying color. If you remove --color option from the ls command, they won't show up. You could also use --color=auto which causes to ls to only send color codes when it is talking to a terminal.

Thank you so much for the professional explanation.
I am wondering if there is any other weird chars I need to guard against in addition to the ANSI color codes.
Is that possible that some other options of some other commands may include in the standardin some control chars
I can not detect with regular perl regexp patterns?
Have a good weekend. ginger
