I need to get the source code for several simple applications in Linux that an app I want to use is dependent on, but which aren't included in the busybox I have. I think I'll need to build these apps and put them in by hand.

One of them, for example, is the cal application (which can print out simple calendars).

Could someone point me to the source code for this app (and, hopefully, others like it that I might later find I need)?

Thanks in advance for any help you can lend. I've been trying to search Linux build trees and have been pretty unsuccessful.

(If it streamlines the problem, I've been trying to use rottlog, a replacement for logrotate that uses bash rather than C code.)

Look in the util-linux or bsdutils package. In util-linux, cal is part of the misc-utils.

Thank you so much! This seems to be exactly what I was looking for.
