The mkbranch command creates a new branch in the version trees of one or more elements. The new branch is checked out, unless you use the -nco option. In Attache, after the command is executed, any files checked out successfully are downloaded to the workspace.
The checkout command sometimes invokes mkbranch automatically. If the view's version of an element is selected by a config spec rule with a -mkbranch branch-type clause, checkout does the following:
Creates a branch of type branch-type.
Checks out (version 0 on) the newly created branch.
Similarly, entering a mkbranch command explicitly can invoke one or more additional branch-creation operations. See Multiple-Level Auto-Make-Branch in the checkout reference page.
Identities: You must have one of the following identities:
Element group member
Element owner
VOB owner
root (UNIX)
Member of the ClearCase group (ClearCase on Windows)
Local administrator of the ClearCase LT server host (ClearCase LT on Windows)
Locks: An error occurs if one or more of these objects are locked: VOB, element type, branch type, element, pool (nondirectory elements).
Mastership: (Replicated VOBs) Your current replica must master the branch type.
EVENT RECORDS AND COMMENTS. Default: Creates one or more event records, with commenting controlled by your .clearcase_profile file (default: -cqe). See the comments reference page. Comments can be edited with chevent.
SUPPRESSING WARNING MESSAGES Default: Warning messages are displayed.
CHECKOUT OF THE NEW BRANCH. Default: The newly created branch is checked out. Additional checkouts may ensue; see the Auto-Make-Branch section.
SPECIFYING THE BRANCH TYPE. Default: None.
type-name | Name of the branch type | |
vob-selector | VOB specifier | |
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) |
SPECIFYING THE BRANCH POINTS. Default: None.

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. In Attache, cmd-context represents the workspace prompt.
On a UNIX system, create a branch type named bugfix. Then, set a view (in Attache, a workspace) with a config spec that prefers versions on the bugfix branch, and create a branch of that type in file util.h.
cmd-context mkbrtype -c "bugfixing branch" bugfix
Created branch type "bugfix".
cmd-context setview smg_bugfix (ClearCase and ClearCase LT)
cmd-context setws smg_bugfix (Attache)
cmd-context mkbranch -nc bugfix util.h
Created branch "bugfix" from "util.h" version "/main/1".
Checked out "util.h" from version "/main/bugfix/0".
On a Windows system, create a branch type named bugfix. Then, set a view drive (in Attache, a workspace) with a config spec that prefers versions on the bugfix branch, and create a branch of that type in file util.h.
cmd-context mkbrtype -c "bugfixing branch" bugfix
Created branch type "bugfix".
> net use y: \\view\smg_bugfix (ClearCase and ClearCase LT)
...
> y:
cmd-context setws smg_bugfix (Attache)
cmd-context mkbranch -nc bugfix util.h
Created branch "bugfix" from "util.h" version "\main\1".
Checked out "util.h" from version "\main\bugfix\0".
Create a branch named rel2_bugfix off the version of hello.c in the view, and check out the initial version on the branch.
cmd-context mkbranch -nc rel2_bugfix hello.c
Created branch "rel2_bugfix" from "hello.c" version "/main/4".
Checked out "hello.c" from version "/main/rel2_bugfix/0".
Create a branch named maintenance off version /main/1\main\1 of file util.c. Do not check out the initial version on the branch.
cmd-context mkbranch -version \main\1 -nco -nc maintenance util.c
Created branch "maintenance" from "util.c" version "\main\1".
Create a branch named bugfix off version /main/3 of file hello.c, and check out the initial version on the branch. Use a version-extended pathname to specify the version.
cmd-context mkbranch -nc bugfix hello.c@@/main/3
Created branch "bugfix" from "hello.c" version "/main/3".
Checked out "hello.c" from version "/main/bugfix/0".
For each file with a .c extension, create a branch named patch2 at the currently selected version, but do not check out the initial version on the new branch. Provide a comment on the command line.
cmd-context mkbranch -nco -c "release 2 code patches" patch2 *.c
Created branch "patch2" from "cm_add.c" version "\main\1".
Created branch "patch2" from "cm_fill.c" version "\main\3".
Created branch "patch2" from "msg.c" version "\main\2".
Created branch "patch2" from "util.c" version "\main\1".
