Hi Thanks for your reply.
I should have been more clear.

For ex
I have below files

a.txt
b.txt
c.txt
d.txt

I want to search each file for the special characters and print the file containing the special characters.
I have wrote a script below.

for line in $(cat newfile2) ; do
 if [[  (cat $line | grep $ ) ]]

        then
                echo $line
else
        echo "No Files available"
fi
done

Please use code tags as required by forum Rules!

I'm not sure your code snippet will do what you want it to do

  • it has a syntactical error
  • it doesn't examine the files for scandinavian nor special chars (given newfile2 holds all those filenames)

To achieve what I think you want,

LC_ALL=C grep '[^[:alnum:][:space:]#$%]' *.txt

might suffice, although with 3000 files that command might exceed LINE_MAX. Use an ls piped into a while loop , then.
