string in a string
Hi,
I m working on a solution which wud script the following scenarios but not quite getting to work 100%.
Case1(very simple)
S1: HELLO_WORLD_HOW_ARE_YOU
S2: HELLO
Easy n simple soln wud be : echo "$S1" | grep "$S2"
Case2:
S1:HELLO_WORLD_HOW_ARE_YOU
S2:HELLO_HOW_ARE_YOU
In this case, above soln would not return TRUE though my S2 is indeed part of S1 but S2 is basically not Continuous.
I am looking for a soln which wud throw a 1 in the above case.
Case3:
S1:HELLO_WORLD_HOW_ARE_YOU
S2:HELLO_JOHN or HI_WORLD
Even this shud return a TRUE.
Basically my intention is, even if a particular pattern in S2(need not be the entire string S2) matches somewhere in S1, I shud get a TRUE .
Plz remember, both S1 and S2 are not Fixed length !
Any ideas?.

DESCRIPTION
The checksecurity command runs a small collection of simple system checks which are designed to catch a few common security issues. check-
security is run by cron in a daily basis.
CONFIGURATION
The checksecurity.conf file defines several configuration variables: MAILTO, CHECK_DISKFREE, CHECK_PASSWD and CHECK_SETUID LOGDIR. Each is
described below.
The checksecurity program works with a collection of plugins which are located in /usr/share/checksecurity and are configured individually
by their own configuration file.
CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked. This script is designed to report upon system accounts
which have no passwords. CHECK_DISKFREE If this is set to TRUE then the check-diskfree script will be invoked and will allow an alert to
be sent if there is any mounted partition is running short on disk space. CHECK_SETUID If this is set to TRUE then the check-setuid script
will be invoked, this will compare the setuid binaries upon the system to those that existed previously and show the differences.
