Hi meharo,

Thanks for your reply. How can we modify the code if we need to search for multiple files.

 
#!/bin/bash
 
my_file1="/mylocation/myfile1.log"
my_file2="/mylocation/myfile2.log"
my_string="Match Found"
 
tail -F "$my_file1" "$my_file2" | while read line ; do
if test -n "$(echo "$line" | grep "$my_string")" ; then
echo "Match found!"
exit 0
else
exit 1
fi
done

to recursively search a string in files in a dir try

find . -name <name / pattern of your file> -print | xargs grep <string to be searched> 2>/dev/null

Cheers
