Script to find diff between labels in ClearCase

     A simple bash script, using cleartool,  to show files that have the new label, but not the old one. Supposedly modified files are label correctly with new label, the script will show the files modified between two labels, in ClearCase. It will also show the creator of the new version. There is also a grep with regular expression filter on the output, to show only the files with .c, .cpp, .h, ... extensions.

#! /bin/bash
# Script to show diffs between 2 ClearCase labels

#cleartool location
export CT=/usr/atria/bin/cleartool

function usage() {
 echo "Usage: cc_dif.sh <new_label> <old_label>"
 exit
}

if [ $# -ne 2 ] ; then
 usage
 exit
else
 echo -e "\t-- New label: $1 --"
 echo -e "\t-- Old label: $2 --\n"
fi

${CT} find . -version "{(lbtype($1) && ! lbtype($2))}" -exec 'cleartool describe -fmt "%Xn \t\tBy: %Fu (%Lu) \n" $CLEARCASE_PN' | grep -E '.*\.(c|cpp|h|hpp|xml)@'
