I want to find how many .py files I have in my GarlicSim directory and all its sub-directories. How do I do that? Either Windows or Linux is fine.

On Linux:

find /path/to/GarlicSim -type f -name "*.py" | wc -l

This command works on any unix/POSIX system, not just Linux. It even works on Windows provided you have any unix/POSIX compatibility package installed (Services For Unix, Cygwin, msys, GNUwin32, UWIN, ...) – Gilles Sep 29 '10 at 20:50
find $DIR -type f | sed 's/.*\.//' | sort | uniq -c  | sort -rn

For the unix-unitiated: this command lists the number of files under $DIR for each extension; the output is sorted by decreasing count. – Gilles Sep 29 '10 at 20:51
