Just a little observation - 's/:.*//' seems a tad simpler than the
sed command suggested (I use it all the time for similar purposes,
e.g. "file * | fgrep text | sed 's/:.*//' | xargs ls -l", interactively,
to long-list text-files only).  Either will give problems on filenames 
with embedded colons, but my suggestion's a bit easier to fix - just
place a tab between the colon and the dot.
