Then do it again, then do your cd, then do it a third time. If the .bashrc is simply malformed, then the alias ought not to work even the first time. But you reported that it does work once. If the alias is set immediately after "source", but then goes away immediately, then you're probably clobbering it in a DEBUG trap, or in a PROMPT_COMMAND. If the alias persists after the first type command, but goes away when you cd, then you've probably got an alias or function overriding the cd command.

I can reproduce this only if the other directory contains nothing but data files which do not get a fancy color. (I put the alias into ~/.bashrc and start a new xterm to get it into effect.)

If I change to another directory - it doesn't work! Use the command "type l" before and after changing directory, to be sure your alias is still set the way you expect. It's possible that you've overridden the "cd" command in such a way that it removes or changes your aliases (although that would be a pretty unusual thing to do).
