Grep and delete lines except the lines with strings
Hi

I am writing a script which should read a file and search for certain strings 'approved' or 'removed' and retain only those lines that contain the above strings.

Ex: file name 'test'
test:
Code:
approved package
waiting for approval package
disapproved package
removed package
approved package
approved package

Here i need to delete all the lines except those that contain either 'approved' or 'removed'.

How can i do that.

FILES

       debian/package.bug-script
	   This is the script to be run by the bug reporting program for generating a bug report template. This file is installed as
	   usr/share/bug/package in the package build directory if no other types of bug reporting customization files are going to be installed
	   for the package in question. Otherwise, this file is installed as usr/share/bug/package/script. Finally, the installed script is given

	   usr/share/bug/package/control in the package build directory.

       debian/package.bug-presubj
	   The contents of this file are displayed to the user by the bug reporting tool before allowing the user to write a bug report on the
	   package to the Debian Bug Tracking System. This file is installed as usr/share/bug/package/presubj in the package build directory.

OPTIONS

       -A, --all
	   Install debian/bug-* files to ALL packages acted on when respective debian/package.bug-* files do not exist. Normally, debian/bug-*
	   will be installed to the first package only.
