Regular expression find command cygwin?

I've never been able to get regular expressions in Cygwin to work for me.
Here's some background info: -find (GNU findutils) 4.5.12 I have the following files in my directory: 

-rw-rwxr--+ 1 None  0 Jun  4 19:16 eiooo.txt
-rw-rwxr--+ 1 None  0 Jun  4 19:20 g.py
-rwxrwx---+ 1 None 96 Jun  4 16:03 giibblejklxx_ekkwll.py
-rw-rwxr--+ 1 None  0 Jun  4 19:16 huuu.txt
-rw-rwxr--+ 1 None 20 Jun  4 19:17 more
-rw-rwxr--+ 1 None  0 Jun  4 19:20 v.py

I want to match strings whose ending is pys.
I try the following:

 find -name "*py$"

and I get nothing.

I also try:

 find -regex "*.py$"

and get nothing.

Am I using regular expressions correctly? It was my understanding that the "$" means "ends with". Is that true? I know that I could leave the dollar sign out in this case, but I want to practice different kinds of regular expressions, and "$" (and "^", actually) never seem to work with the find command.

Any suggestions? Thank.

Solution

  • -name and -iname use globs, not regular expressions. And -regex and -iregex will be false if the regular expression is invalid. Also note that -regex and -iregex attempt to match the entire path, not just the filename.
