How to grep all the files inside the directory and Sub directory
Hi,

I have used the command
Code:
cat * | grep -r <<String>> *

It returns:

Code:
cat : JAN : is directory

***********************
*********************

My directory structure:

Code:
     log
       - JAN
          -catalina.out
       -FEB
          -catalina.out
      -MARCH
          -catalina.out


Please Suggest me

Regards,
Nanthagopal

By grep string1 file| grep string2, I assume that you require to search and print those lines which contain both string1 and string2. This could be done like this:
Code:
grep -E 'string1.*string2|string2.*string1' file

Use below code to search through all the files from the directory ...

Code:
#Single Directory --
grep -r "text" /path/*

#Multiple Directory --

grep -r "text" /path/* /path2/*
