linux tips : search inside archives

search for a file inside a path containing archives ( .tar.gz .tgz ) I had the following problem : many archives ( .tar.gz ) and i needed to find where is located a specific file, so i came up with the following script:

#/bin/bash
#script to find a file inside an archive in a specific path

if [ $# -eq 2 ] ; then
 LIST=`find $1 -name '*.tar.gz'`
 
 for file in $LIST
 do
  result=`tar -tzvf $file | grep -c $2`
  
  if [ $result -gt 0 ] ; then
   echo "Found in $file"
   echo  "  `tar -tzvf $file | grep $2`"
  # tar -tzvf $file
  fi
 done
else
 echo usage : $0 path_to_search name_to_find
fi


exit 0
