learning more abput re

[Skaperen]

i want to learn more about regular expression and the re module. particularly expression substitution. as an exercise, i plan to write a command that can do a mass rename file by providing a match string and substitution as needed.

what are good places to find tutorial type help for this? i have the reference manual, but i'm not learning very well from it.

check https://www.regular-expressions.info/ for general and also language specific (not just python) info on regex. I find it useful. Also regex101.com for testing

my project idea had the rug pulled out from under it. a perl command called rename that does this is included in ubuntu.
