Assign a tag to the sandbox revisions of a set of files. You can use the status -v command to list the existing tags for a file.

The tag must start with a letter and consist entirely of letters, numbers, dashes, and underscores. Therefore, while you might want to tag your hello project with 1.0 when you release Version 1.0, you’ll need to tag it with something like hello-1_0 instead.

The standard meanings of the common client options -D, -f, -l, -r, and -R apply. Additional options are:

-b

Make a branch.

-c

Check for changes. Make sure the files aren’t locally modified before tagging.

-d

Delete the tag.

-F

Force. Move the tag from its current revision to the one specified.

Because the -d option throws away information that might be important, you should use it only when absolutely necessary. It is usually better to create a different tag with a similar name.
