Hi,

This will give me the location of all the files.

find /dir/to/search -name "*.txt" | xargs grep -l xyz

But how do I write a script that will go into each directory and again search for another pattern from the *.txt file.

example
--------
if xyz pattern is found in the following directories.

dir2/subdir2/subsubdir2/file1.txt
dir3/subdir3/file2.txt
dir4/subdir4/subsubdir4/file3.txt


Please do not get confuse my actual requirement is to find the files in different directories which contains pattern xyz

Then go to each of the directories where you found xyz pattern in that file and again search for 2nd pattern from this file.

Appreciate your help.

Thanks
imas
