I want to get the filename (without extension) and the extension separately.

The best solution I found so far is:

NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`

This is wrong because it doesn't work if the file name contains multiple . characters. If, let's say, I have a.b.js, it will consider a and b.js, instead of a.b and js.

It can be easily done in Python with

file, ext = os.path.splitext(path)

but I'd prefer not to fire up a Python interpreter just for this, if possible.

Any better ideas?

How do I get rid of all the broken symlinks I just created in a single fell swoop?

I've got a program that adds to a log file while it's running. Over time that log file gets huge. I'd like to create a startup script which will rename and move the log file before each run, effectively creating separate log files for each run of the program.
