grep spool file error
Hi,
I am trying to do this
For i in *.txt
do
sed 'some pattern checking' $i
done
>file

These text files are spool files.And when i find error in these spool files I want to append the text file contents to error.log file.
Or is there any option that I do this sed for only files that does not contain errors?
Can some one tell me how can i do this please..

this would give you a list of files that contain the pattern you are looking for:
Code:
grep -l 'pattern_to_check' * | sort | uniq

so you could do:
Code:
for file in `grep -l 'pattern_to_check' * | sort | uniq`
do
    cat $file  >> error.log
done

I don't think you need the sort | uniq because grep will only print each file name once. In any event, the purpose of cat is to concatenate multiple files, so you really don't need the loop either.

Code:
cat `grep -l 'pattern_to_check' *.txt` >>error.log

If I use like grep -v 'ERROR' *.txt then I get lines also from the text files which do not have ERROR pattern
I want to grep only files that do not have the pattern

I even used 'grep -r exclude' option but some how syntax is wrong I think so.

Please tell me the exact command
