The Question is:
What is the command to compare files based on date?
Where can I get a manual describing the various Open VMS commands?
The Answer is :
Your question on date-based file comparisions is sufficiently terse
as to be quite difficult for the OpenVMS Wizard to answer.
There are a variety of date-related mechanisms within OpenVMS, ranging
from /SINCE and /BEFORE qualifiers, DCL lexical functions that permit
the retrieval and/or the conversion of dates and date formats (f$time,
f$file_attributes, f$cvtime, etc), and the format of the absolute, delta,
and combination times on OpenVMS. File comparisions can include the
DIFFERENCE command -- which itself supports /SINCE and /BEFORE -- and
various DCL lexical functions such as f$search and f$file_attributes.
As for your second question -- please, one question to a posting -- please
see the OpenVMS FAQ for pointers to OpenVMS training materials, Compaq and
customer websites, and to the available OpenVMS documentation.
