Um, yeah, or you could just compare "tag-name" to the tag associated with
your current sandbox:
$ awk -FN '{print $2}' < CVS/Tag

Subject: Checking if two versions are the same
Hi,
I have a tag name, and a working directory of some project (without a sticky
tag). I want to know if the tag name denotes the same version as my working
directory. What is the right way to find out?
Suppose that I have just checked-out this working directory (i.e. only the
files from CVS are in the working directory, and I have not touched them) -
is the following algorithm correct?
1. Run: cvs -qn update -r tag-name
2. If this command had no output at all, then the tag name denotes the same
as the checked-out version. If the command had output (either on stdout or
on stderr), then the tag name denotes a different version.
[ In any case, I would prefer a simpler solution, in which I don't need to
check stderr, and preferrably even not stdout, only the exit status of a
command. This is because the algorithm needs to run in several environments.
]
Thanks,
Shlomo
