This looks fragile; e.g., take my own /home:

blp@pfaff:~(0)$ ls -l /home
total 16
drwxrwxr-x   89 blp      blp          8192 Jul 12 09:40 blp/
drwxr-xr-x    5 root     root         4096 Jun 13  2001 teams/
drwxr-xr-x    2 timd     timd         4096 Jul  6  2001 timd/

Now consider the lines that don't contain any colons at all.

What's wrong with `/home/*'?

for d in `...your command...'; do cp file-i-want /home/$d; done
