# Tagging files with a label

To tag a set of file revisions (in addition to any revisions that have already been tagged), use `p4 tag`, specifying a label name and the desired file revisions.

For example, to tag the head revisions of files that reside under `//JamCode/release/jam/2.1/src/` with the label `jam-2.1.0`, issue the following command:

    p4 tag -l jam-2.1.0 //JamCode/release/jam/2.1/src/...

To tag revisions other than the head revision, specify a changelist number in the file pattern:

    p4 tag -l jam-2.1.0 //JamCode/release/jam/2.1/src/...@1234

Only one revision of a given file can be tagged with a given label, but the same file revision can be tagged by multiple labels.
