You can avoid loops by using sed itself to create sed script:

Code:
sed -e 's!^!/!;s!$!/d!' list.txt > sed.scr;  sed -f sed.scr datafile

Hi Sekhar,

You can use foreach command

foreach i (`cat stringlist.txt`)
sed '/$i/d' fileList.txt >> temp_fileList.txt
end

mv temp_fileList.txt stringlist.txt

Thanks
