You're asking an awful lot of questions that are basic, UNIX
scripting how-to stuff. You should consider reading a basic shell
programming book. You'd save a lot of time -- sooner than you may
think.
In answer to your question, just pipe your date into:
awk -F: '{print $1}'
If you're really pressed for time, you should, at least, read the
"sed" and "awk" man pages if you need to manipulate a lot of text
files. O'Reilly sells a good book on sed & awk, too. (Perl is
slicker in some ways, but I wouldn't worry about that until I had a
better grip on the more widely-used tools (such as sh, sed, awk...).)
