Removes a version label from a version


ProductCommand type
ClearCasecleartool subcommand
ClearCase LTcleartool subcommand



rmlabel [ –c·omment comment | –cfi·le comment-file-pname |–cq·uery
| –cqe·ach | –nc·omment ]
[ –ver·sion version-selector ] label-type-selector pname ...


The rmlabel command removes one or more version labels from versions of elements. Labels can be attached to versions by the mklabel command and by triggers (mktrtype –mklabel).

rmlabel deletes a reference to a label type object. To delete the label type object itself or the type object and all its instances, use the rmtype command.



You must have one of the following identities:

  • Element owner
  • Element group member
  • VOB owner
  • root (UNIX)
  • Member of the ClearCase administrators group (ClearCase on Windows)
  • Local administrator of the ClearCase LT server host (ClearCase LT on Windows)


An error occurs if one or more of these objects are locked: VOB, element type, element, branch type, branch, label type.


(Replicated VOBs only) If the label type is unshared, your current replica must master the label type. If the label type is shared, your current replica must master the object whose label you are removing:

  • For a one-per-branch shared label type, your current replica must master the branch.
  • For a one-per-element shared label type, your current replica must master the element.

Other Restrictions

You cannot use this command to remove an instance of a UCM baseline label type.


Event Records and Comments

Creates one or more event records, with commenting controlled by your .clearcase_profile file (default: –nc). See the comments reference page. Comments can be edited with chevent.

–c·omment comment | –cfi·le comment-file-pname |–cq·uery | –cqe·ach | –nc·omment
Overrides the default with the option you specify. See the comments reference page.

Specifying the Versions to Be Unlabeled


pname ...
One or more pathnames, indicating versions from which the label is to be removed. What kind of pathname is valid depends on how the label has been used:

If the label has been used only once in an element's version tree, you can specify the element itself or any of its branches or versions:

foo.cVersion selected by view
foo.c@@Element itself
foo.c@@/main/rel2_bugfixBranch of element

If the label has been used multiple times, you must specify either the version to which the label is attached, or the branch on which that version resides.

foo.c Version selected by view
foo.c@@\REL1 Version specified by label
foo.c@@\main\rel2_bugfix\3 Version specified by version ID
foo.c@@\main\rel2_bugfix Branch on which version resides

Using the –version option modifies the way in which this argument is interpreted.

–ver·sion version-selector
Specifies the version from which the label is to be removed. See the version_selector reference page for syntax details. Using this option overrides a version-extended pathname. For example:
cmd-context rmlabel XXX util.c@@/REL1 Removes label from version REL1.
cmd-context rmlabel -ver /main/3 XXX util.c@@/REL1 Removes label from version /main/3

Specifying the Label to Be Removed


An existing label type. Specify label-type-selector in the form [lbtype:]type-name[@vob-selector]
type-name Name of the label type
vob-selector VOB specifier

Specify vob-selector in the form [vob:]pname-in-vob

 pname-in-vob Pathname of the VOB tag (whether or not the VOB is mounted) or of any file system object within the VOB (if the VOB is mounted)


The UNIX examples in this section are written for use in csh. If you use another shell, you may need to use different quoting and escaping conventions.

The Windows examples that include wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the UNIX shell or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt.

  • Remove the label REL3 from a version of msg.c without specifying which version (assumes the label is attached to one version only).

    cmd-context  rmlabel REL3 msg.c
    Removed label "REL3" from "msg.c" version "/main/1". 

  • Remove the label REL2 from the version of element util.c specified by a version selector.

    cmd-context  rmlabel –version \main\REL2 REL2 util.c\
    Removed label "REL2" from "util.c" version "\main\1". 

  • Remove the label REL1.1 from version 1 on the maintenance branch of file element util.c. Use a version-extended pathname to indicate the version.

    cmd-context  rmlabel REL1.1 util.c@@/main/maintenance/1
    Removed label "REL1.1" from "util.c" version "/main/maintenance/1".
