Using find to locate files that match one of multiple patterns
Use -o, which means "or":
find Documents \( -name "*.py" -o -name "*.html" \)You'd need to build that command line programmatically, which isn't that easy.
Are you using bash (or Cygwin on Windows)? If you are, you should be able to do this:
ls **/*.py **/*.htmlwhich might be easier to build programmatically.
Some editions of find, mostly on linux systems, possibly on others aswell support -regex and -regextype options, which finds files with names matching the regex.
for example
find . -regextype posix-egrep -regex ".*\.(py|html)$" should do the trick in the above example.However this is not a standard POSIX find function and is implementation dependent.
