Unix Script to compare two files

Hello,

I have a dat file nctilllist.dat which will be present in the directory path
"/usr/lpp/web-data/mfg/nct/file-data/nctilllist.dat"

nctillist.dat will have reference to files like DP100001.jpg,DP10002.PDF,DP100003.doc

on the path /usr/lpp/web-data/mfg/nct/file-data will have original contents of files
DP100001.jpg,DP10002.PDF,DP100003.doc

I want to write a script to open the file nctillist.dat and read the file and compare them whether any matching file name is present in the link /usr/lpp/web-data/mfg/nct/file-data

ex: open nctillist ,read first name DP100001.jpg compare any similar name is present in the path /usr/lpp/web-data/mfg/nct/file-data ,
if yes move the original file in path /usr/lpp/web-data/mfg/nct/file-data to /usr/lpp/web-data/mfg/nct/file-data\purgedocs.

can anyone suggest how to write a script for this scenario.

Thanks

Code:
#! /bin/bash

while read x
do
    if [ -e /usr/lpp/web-data/mfg/nct/file-data/purgedocs/$x ]
    then
        echo "$x already present in purgedocs. Moving to next entry in nctilllist.dat."
        continue
    fi
    if [ -e /usr/lpp/web-data/mfg/nct/file-data/$x ]
    then
        cp /usr/lpp/web-data/mfg/nct/file-data/$x /usr/lpp/web-data/mfg/nct/file-data/purgedocs/
    else
        echo "$x not found in file-data. Moving to next entry in nctilllist.dat."
    fi
done < /usr/lpp/web-data/mfg/nct/file-data/nctilllist.dat

Thank you so much !! Its working

---------- Post updated at 10:48 AM ---------- Previous update was at 10:45 AM ----------

I have one more question , I invoke this script through a Mainframe job . When I run through Mainframe its saying the following error
/usr/lpp/web-data/mfg/nct/file-data/nctill_tar.sh 1: FSUM7729 missing closing "'"…

But when i run through putty its working as expected.

Any idea on this?

I don't understand when you say mainframe job.
1. Is it a part of a larger script?
2. As the error suggests, have you missed out on a closing quote somewhere?

Im basically a mainframe developer ,we have a mainframe pgm where we give all the path details to run the script from a mainframe pgm.

When i try running the script through mainframe pgm its giving the above error , but when run paste the same code in putty its working fine.

script i used

#!/bin/bash
cat {"/usr/lpp/web-data/mfg/nct/file-data/nctilllist.dat"}
while read x
do
if [ -e /usr/lpp/web-data/mfg/nct/file-data/purgeDocs/$x ]
then
echo "File already present in purgedocs. Continuing to next file."
continue
fi

if [ -e /usr/lpp/web-data/mfg/nct/file-data/$x ]
then
cp /usr/lpp/web-data/mfg/nct/file-data/$x /usr/lpp/web-data/mfg/nct/file-data/purgeDocs/
else
echo "$x not found in file-data. Moving to next entry in nctilllist.dat."
fi
done < /usr/lpp/web-data/mfg/nct/file-data/nctilllist.dat

Thanks

cat {"/usr/lpp/web-data/mfg/nct/file-data/nctilllist.dat"} => This doesn't appear to be valid. What're you trying to achieve?

Old 02-05-2012
ex:
/usr/lpp/web-data/mfg/nct/file-data/nctilllist.dat will have
DP10001.jpg
DP10002.pdf
DP10003.xls

/usr/lpp/web-data/mfg/nct/file-data/ will have
DP10001.jpg
DP10002.pdf
DP10003.xls

compare
/usr/lpp/web-data/mfg/nct/file-data/nctilllist.dat
/usr/lpp/web-data/mfg/nct/file-data/

if matching move the file from
/usr/lpp/web-data/mfg/nct/file-data/
/usr/lpp/web-data/mfg/nct/file-data/purgedocs

in the above case all the three files will be moved to
/usr/lpp/web-data/mfg/nct/file-data/purgedocs
since both has the same files.

Im listing the file nctillist.dat with that CAT cmd

let me know if im worng

Thanks
