Normally one does not modify tags. They exist in order to record the history of the repository and so deleting them or changing their meaning would, generally, not be what you want.
However, there might be cases in which one uses a tag temporarily or accidentally puts one in the wrong place. Therefore, one might delete, move, or rename a tag. Warning: the commands in this section are dangerous; they permanently discard historical information and it can difficult or impossible to recover from errors. If you are a CVS administrator, you may consider restricting these commands with taginfo (see section User-defined logging).
To delete a tag, specify the `-d' option to either
cvs tag
or cvs rtag
. For example:
cvs rtag -d rel-0-4 tc
deletes the tag rel-0-4
from the module tc
.
When we say move a tag, we mean to make the same
name point to different revisions. For example, the
stable
tag may currently point to revision 1.4
of `backend.c' and perhaps we want to make it
point to revision 1.6. To move a tag, specify the
`-F' option to either cvs tag
or cvs
rtag
. For example, the task just mentioned might be
accomplished as:
cvs tag -r 1.6 -F stable backend.c
When we say rename a tag, we mean to make a
different name point to the same revisions as the old
tag. For example, one may have misspelled the tag name
and want to correct it (hopefully before others are
relying on the old spelling). To rename a tag, first
create a new tag using the `-r' option to
cvs rtag
, and then delete the old name. This
leaves the new tag on exactly the same files as the old
tag. For example:
cvs rtag -r old-name-0-4 rel-0-4 tc cvs rtag -d old-name-0-4 tc
