I need to do a listing using either ll or ls that can allow me to lsit files in all directories and subdirectories.
I've tried the following:
ls -lsr / * | grep *.conf and this give me a listing but with the path and I need that info.
Also can I have more than 1 grep on the same command line? eg if I want listing for both .cfg and .conf.

Thanks
