Breaking down a script

[mechaflash]

Hi Everyone!

Working with Red Hat Enterprise Linux ES release 4 (Nahant Update 4)

Working at a new company, and the previous guy had created a shell script to take care of a specific task. His role was unique as the manager took advantage of his programming ability (wasn't a part of his job). On top of that, I'm no programmer either . I'm trying to figure out what this script is doing because it's throwing a warning.

REM this is remove /home/public/ccnf* (remove anything that starts with ccnf)
rm /home/public/ccnf*

REM i understand that this retrieves anything that starts with ccnf that has been changed at any given time, but I don't understand anything else after -ctime...
find /usr/CC/DATA1/RPT/ -name "ccnf*" -ctime -1 -print | xargs fgrep -l "GB-1 " > /tmp/t.file


REM while read line = read each line that is "printed" from the above command?
while read line

do

REM copy each line that was read from above command to /home/public/
cp -p $line /home/public/


REM don't know about this one =(
done < /tmp/t.file

REM remove /tmp/t.file that was made by previous command?
rm /tmp/t.file

If someone can help me break this down and fill in the shady spots for me that would be great

Telling us what the warning is might be useful.

His script rather creatively does the following;

Removes some files from /home/public

Looks for lines containing the string GB-1 in files under /usr/CC/DATA1/RPT/ that have been changed less than 24 hours ago, and then takes those matched strings (which are presumably filenames) and copies them to /home/public.... a slightly less insane way of accomplishing this in two lines would be....

rm -f /home/public/ccnf*

find /usr/CC/DATA/RPT -name "ccnf*" -ctime -1 -print | xargs fgrep -l "GB-1" | xargs -i cp -p {} /home/public

You're gonna laugh when you hear this -.- They didn't inform me that it happens only on specific days. The warning that is received is that the script can't remove ccnf* (not found) and that's because no data is being written over the weekend (they only receive the warning every Sunday and Monday morning =/)
