ClearCase Support: How to Make a ClearCase Branch
You may be asking yourself how to create a branch in ClearCase from the command line. Here's how!
First, create a branch name (this is called a branch type) in the VOB that you want to make the branch in:
$ cleartool mkbrtype TEST_BRANCH
Comments for "TEST_BRANCH":
Created branch type "TEST_BRANCH".
Don't forget to enter a comment for the branch type, or you can use the "-nc" argument for no comment.
Now, you are ready to make a branch on an element in ClearCase, using this command:
$ cleartool mkbranch -nc TEST_BRANCH filename.txt
Created branch "TEST_BRANCH" on "filename.txt" from version "/main/179".
Checked out "filename.txt" from "/main/TEST_BRANCH/0".
