yes Dave told me to stop top posting and CC tutor at python.org..sorry about
that i didnt know.

as far as print zip_command, i would add that to the program however, doesnt
just declaring it actually trigger it..thus it would executed and the
command line would get printed as well?

the actual program i was looking to write would take:
 file1,file2,and file3, in /Users/davidteboul/bin/python
and condense them into individual files; file1.gz, file2.gz and file3.gz and
save them in a directory already made - (/Users/davidteboul/backups)


ps..did i post and reply all corretly?
