Synopsis
- chbl [ –c/omment comment | –cfi/le comment-file-pname | –cq/uery
- | –cqe/ach | –nc/omment ]
{ [ [ –inc/remental | –fu/ll ] [ –nre/curse ] ]
[ –level promotion-level ] } baseline-selector ...
Description
The chbl command modifies one or more baselines. You can modify a baseline's labeling status or assign a new promotion level to a baseline.
For information about changing the baseline's name, see rename.
Baseline labels
Baselines can be unlabeled, incrementally labeled, or fully labeled. Only labeled baselines can be used to configure streams (see rebase and mkstream). After they are applied, baseline labels cannot be moved.
Promotion levels
Promotion levels must be defined in the baseline's project VOB before they can be applied to baselines. For information about promotion levels, see the setplevel reference page.
The promotion levels available in a VOB can be listed by running the describe command on the UCM project VOB object.
Restrictions
Identities
You must have one of the following identities:
- Project VOB owner
- Baseline owner
- Stream owner
- root (UNIX and Linux)
- Member of the ClearCase administrators group (ClearCase on Windows only)
Locks
An error occurs if there are locks on any of the following objects: the UCM project VOB, the baseline.
Mastership
(Replicated VOBs only) Your current replica must master the baseline.
Options and arguments
Event records and comments
- Default
- 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.
Changing a baseline's labeling status
- Default
- None.
- –inc/remental
- Changes the labeling status for an unlabeled baseline to incremental. This option has no effect if the baseline is already incrementally or fully labeled.
- –fu/ll
- Changes the labeling status for a baseline from unlabeled or incremental to full. This option has no effect if the baseline is already fully labeled. A chbl –full operation may take a long time for components with many elements.
- –nre/curse
- By default, when –incremental and –full are used on a composite baseline, the specified change is applied recursively to its member baselines. The –nrecurse option is used to prevent the default behavior. It causes the changes to apply only to the composite baseline and not its members.
Assigning promotion levels
- Default
- No change in promotion level.
- –level promotion-level
- Sets the promotion level for the specified baselines. The specified promotion level must be defined in the baseline's project VOB. When used on a composite baseline, the change is not applied recursively to its members.
Specifying the baseline
- Default
- None.
- baseline-selector ...
- Specifies one or more baselines to modify.
baseline-selector is of the form [baseline:]baseline-name[@vob-selector], where vob-selector specifies the baseline's project VOB.
Examples
The UNIX system and Linux examples in this section are written for use in csh. If you use another shell, you might 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 might 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 system and Linux shells or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt.
- Change an unlabeled baseline to be incrementally
labeled. The baseline specifier includes a VOB component, which must be the
baseline's project VOB.
cmd-context chbl -incremental testbl.121@/vobs_core_projects
Begin incrementally labeling baseline "testbl.121".
Done incrementally labeling baseline "testbl.121". - Change a baseline's promotion level and check
the labeling status. The baseline specifier includes a VOB component, which
must be the baseline's project VOB.
cmd-context chbl -full -level TESTED testbl.121@\core_projects
Change baseline "testbl.121".
Baseline "testbl.121" is already fully labeled.
