Re: Is it possible to change a branch tag name?

[Dale Miller]

John,

To rename an existing tag (not a branch tag) you should be able to:

cvs rtag -r existing_tag new_tag module
cvs rtag -d existing_tag module

However, this does not work with a branch tag unless you use
the -r number instead of name.

Since each file in a branch tag would have different branch numbers
you would have to do this on each file separately.  You could automate
the process but you would have to examine the output of the status -v
command for each file parsing the Existing Tag information to get the
branch number.

The following is an example with some test data.  This example renames the
SCR20000600b (branch tag) and SCR20000600 (revision tag) to
SCR20000601b and SCR20000601.

Example:
cvs status -v SDHSU/isreplace/ids/Make.defs

One of the folks in my group has decided he wants to change the name
of a branch tag, after having done some amount of changing of files on
that branch.  I'd never heard of a way to do that, and a scan of the
docs doesn't reveal anything that looks like a facility for doing
that, but I figured it was worth asking the list:  Is there a way to
change the name of an existing branch tag?

Thanks in advance...
