labelsync -- Apply the label to the contents of the client workspace

p4 labelsync [-a -d -n -q] -l label [file[revRange] ...]

Labelsync causes the specified label to reflect the current contents
of the client. It records the revision of each file currently synced.
The label's name can subsequently be used in a revision specification
as @label to refer to the revision of a file as stored in the label.

Without a file argument, labelsync causes the label to reflect the
contents of the whole client, by adding, deleting, and updating the
label. If a file is specified, labelsync updates the specified file.

If the file argument includes a revision specification, that revision
is used instead of the revision synced by the client. If the specified
revision is a deleted revision, the label includes that deleted
revision. See 'p4 help revisions' for details about specifying
revisions.

If the file argument includes a revision range specification,
only files selected by the revision range are updated, and the
highest revision in the range is used.

The -a flag adds the specified file to the label.

The -d deletes the specified file from the label, regardless of
revision.

The -n flag previews the operation without altering the label.

Only the owner of a label can run labelsync on that label. A label
that has its Options: field set to 'locked' cannot be updated.

The -q flag suppresses normal output messages. Messages regarding
errors or exceptional conditions are displayed.
