How do I get an ls -l to not show the full directory path?

Hey

I'm new to the forums here, and I'm seeking help for this script that I'm writing. When I do ls -l of a directory it shows the full pathname for files in it. For example, if the directory is /internet/post/forum/ and the file is topic, it currently shows internet/post/forum/topic. What's the correct way to get it to just say /topic when I'm ls'ing a directory to see the files within?

Thanks a lot, greatly appreciated.

cd into the directory first:

cd /internet/post/forum/
ls -l
cd $OLDPWD

Thanks!

something like

ls -l | grep sed 's/<Homedirectorry>//g'

ie. replace all homedirectory references with null.
