how to find files in a given branch - clearcase

Question

I noticed that when doing code view, people here in my company usually just give the branch in which his work is done, and nothing else. So I guess there must be a easy way to find out all the files that has a version in the given branch which is the same thing to find all the files
that has been changed.
Yes, I don't know the expected "easy way" to find files in certain branch, so need your help and thanks in advance.

Answer 1

You can quickly list all files from a particular branch:
cleartool find . -type f -branch "brtype(abranch)" -print
I would recommend combining that with:
-user to limit to a particular user, in case several users use the same branch.
cleartool find . -type f -branch "brtype(abranch)" -user aloginname -print
-created_since filter, to find all elements created since a certain date, in case their is incremental review for a work done on the same branch.
cleartool find . -type f -branch "brtype(abranch)" -element "{created_since(10-Jan)}" -user aloginname -print

Here is a python script that does the trick. It may look a lot more complicated but it's copy paste and go. Feel free to swap out the cmd with VonC's.
import subprocess
import os
import sys
from optparse import OptionParser
def pipeCmd(Cmd):
pipe = subprocess.Popen(Cmd,
shell = True,
stdout = subprocess.PIPE,
stderr = subprocess.PIPE )
(stdout_data,stderr_data) = pipe.communicate()
return (pipe,stdout_data,stderr_data)
def main(br_name):
cmd = "cleartool find -vis -avobs -element 'brtype(" + br_name + ")' -exec 'cleartool describe -short $CLEARCASE_PN'"
pipe,data,err = pipeCmd(cmd)
if 0 == pipe.returncode:
print data
else:
print err
# Process cmd arguments
if (1):
if (len(sys.argv) <= 1):
print "Finds all branches in your view."
print "\nExamples:\n"\
"allBranches.py -b $BRANCH_NAME \n"\
"allBranches.py --branch=$BRANCH_NAME\n"
parser = OptionParser()
branchName = "Example: 'rs__BRANCH_NAME_int'"
parser.add_option("-b", "--branch", dest="BRANCH_NAME", help=branchName, metavar="BRANCH_NAME")
(options, args) = parser.parse_args()
if (options.BRANCH_NAME):
print "\nFinding " + options.BRANCH_NAME + " elements...\n"
main(options.BRANCH_NAME)
sys.exit(0)
