Thanks DGPickett. Sure will tryout what you said.

I tried some very simple solution to compare *.txt files from 2 different directories. I was able to compare them and generate sdiff result.

Code:
#!/bin/bash
# cmp_dir - program to compare two directories
# Check for required arguments
if [ $# -ne 2 ]; then
    echo "usage: $0 directory_1 directory_2" 1>&2
    exit 1
fi
# Make sure both arguments are directories
if [ ! -d $1 ]; then
    echo "$1 is not a directory!" 1>&2
    exit 1
fi
if [ ! -d $2 ]; then
    echo "$2 is not a directory!" 1>&2
    exit 1
fi
# Process each file in directory_1, comparing it to directory_2
find $1/ -name '*.txt' -print | while read src
do
for filename in $1/*.txt; do
    fn=$(basename "$filename")
    if [ -f "$filename" ]; then
        #if [ ! -f "$2/$fn" ]; then
            #echo "$fn is missing from $2"
            #missing=$((missing + 1))
        #fi
                sort $filename
                #echo $filename
                sort $2/$fn
                #echo $2/$fn
                sdiff $filename $2/$fn | egrep '>|<|\|' > resultfile.txt
    fi
done
done

when i execute the above script ie,
./filecomp.sh oldfiles newfile

I get the resultfile.txt which will have the sdiff output(with grep). now my problem is not sure how create separate resultfile as it reads files.

I have 2 different folders :
a. oldfiles - conatains several files(*.txt)
b. newfile - contains several files(*.txt)

Files in the two folders will have the same filenames. ie,
oldfiles folder -
aa.txt
bb.txt

newfiles folder -
aa.txt
bb.txt

so, what am trying to do in above script, is to read file aa.txt from oldfiles folder and aa.txt from newfile folder then do sort/sdiff command and then put the result file in output folder with filename aa_result.txt

ie, output folder will contain results
aa_result.txt
bb_result.txt

this where am struck, how to get the separate resultfile on each inputfile.

Anyhelp will be greatful.
