Searching within files in a tarball archive (.tar)

[naveenrv]

Hello there,

I'm relatively new to Unix, and I would like to know the commands/script for searching within files inside a tarball(.tar file).

Let's say I have a file ABC.tar, that contains many files such as X.txt, Y.txt, Z.txt.. One of these files (X,Y,Z..) contains a string 'Hello'. How can i grep within the .tar file to find which file contains the string 'Hello', without extracting the .tar?

Thanks.

F=`tar --list -x ABC.tar`
for Z in $F; do 
  if tar -xOf ABC.tar $Z | grep Hello ; then 
    echo found in $Z
  fi
done

This works for me:

tar -O --wildcards -xf ABC.tar | grep -I -r -i 'Hello' ./

This works for me:

tar -O --wildcards -xf ABC.tar | grep -I -r -i 'Hello' ./

Thank you!
