LINUX - How to compare the values in 2 files & exit from the script
Hi All,
I have a requirement where I need to compare 2 files & if the values in the files match, it should proceed, else exit the script without proceeding further.
For e.g : Scenario 1
Quote:
cat File A
20120701,20120702,20120703
cat File B
20120701,20120702
In this case, the script should exit without proceeding further.
Scenario 2
Quote:
cat File A
20120701,20120702,20120703
cat File B
20120701,20120702,20120703
In this case, the script should proceed further.
Scenario 3
Quote:
cat File A
20120701,20120702,20120703
cat File B
20120701,20120702,20120704
In this case, the script should exit.

PLS NOTE : The date values in File A & B can be in any order. So, i think a diff command might not work.

Can anybody shed some light on how to accomplish this.

Thanks Much
Freddie

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
