Need a help with grep

palanisaravanan · 04-23-2005, 06:58 AM

I am having some 50 files where each file has 10 lines.one particular
string is present in some files where it is not there in other files.
I am trying to find the name of the files where the string is not present
and move the the output to a file for further processing.
I tried the following command

grep -l -v 'string' filename>test

But it is still showing the files where the string in present.

Can any one help me to sort out the problem?

You need to write script something like as follows

Code:

A="ALL FILE NAMES"
for i in $A
do
  grep "string" $i>/dev/null
  [ "$?" != "0" ] && echo $i notfound.txt
done

notfound.txt == list of files in which string does not exists

Yes you can write

A="$1"

And run script as

script "/path/to/files/*"
