# ----------
# PURPOSE
# obtaining a list of automatic labels that would be encompassed by the scope of an automatic label. 
#
# Potential improvements: 
# * performance. This script is doing loops through potentially large chunks of data, and probably not terribly efficiently. 
# * verification. Checking that the parameters passed to the script are valid; improved error-handling; etc. 
# 
# ==========
# get a list of automatic labels
# doing this by checking for 'Revision' in the tagged-output of label spec

autolabels=`p4 -F "%label% Rev:%Revision%" -ztag labels | grep -v "Rev:$" | sed -e "s/ Rev:.*//g"`

# loop through the parameters passed to script (should be depot paths)
# assuming (but not really testing for) file patterns

while [ $# -ne 0 ]
do
	depotpath=$1

	# does 'depotpath' contain at least one file? (a low-quality check)
	# if so, get list of automatic labels, check to see if any file revision
	# in depotpath is encompassed by the automatic label.
	# Finally, if it does, print the output of 'p4 labels' for that label.

	filesExist=`p4 files -m1 $depotpath 2> /dev/null | wc -l`

	if [ "$filesExist" -eq "1" ] 
		then
		for l in $autolabels; do

			labcount=`p4 files $depotpath#1,@$l 2> /dev/null | wc -l`
			
			if [ "$labcount" -gt "0" ]
					then p4 labels -e "$l"
			fi
