Would there be an easier way to do this in perl?

#!/bin/tcsh
#1. Create a file of all disk images from the Netbackup catalog that N
+etbackup thinks is on disk.

echo "Creating list of all images that Netbackup thinks is on disk."
cp /dev/null catall
grep "F:\\backup" cat.txt | sed -e "s/F:\\backup\\/\*/g" | awk -F\* '{
+print "F:\\backup\\" $2}' >> catall
grep "G:\\backup" cat.txt | sed -e "s/G:\\backup\\/\*/g" | awk -F\* '{
+print "G:\\backup\\" $2}' >> catall
grep "H:\\backup" cat.txt | sed -e "s/H:\\backup\\/\*/g" | awk -F\* '{
+print "H:\\backup\\" $2}' >> catall

#2.  Create file of what's on disk

echo "Create file listing of all images on disk."
cp /dev/null dirall
grep "_" Fdir.txt | awk '{print "F:\\backup\\" $5}' > dirall
grep "_" Gdir.txt | awk '{print "G:\\backup\\" $5}' >> dirall
grep "_" Hdir.txt | awk '{print "H:\\backup\\" $5}' >> dirall

#3. sort the files

echo "Sorting the two files"
sort catall > catall.srt
sort dirall > dirall.srt

#4. check em
 
echo "Checking the differences."
diff -u dirall.srt catall.srt |grep "^-" |grep -v "\-\-\-" |sed -e s/\
+-//g > delfile.list

#5. create batch file

echo "Creating a batch file to delete the files that Netbackup doesn't
+ know about."
awk '{print "del " $1}' delfile.list > delfile.bat
