Question Setting the correct parameter
Hi Gurus,

Here is the issue that I've encountered.

Code:
VAR1=`hostname | tr '[a-z]' '[A-Z]'`
-> convert hostname to uppercase

VAR2=`grep $VAR1 /etc/hosts | awk '{ print $1 }'`
-> Since hostname is already in uppercase, grep is unable to find it in /etc/hosts. How to handle VAR2?

Is there a better way to extract the hostname and IP on separate variable?
Please kindly advice on how to extract the IP address.

Thank you.



Regards,
Peter

check-hostname

check-hostname(1M)					  System Administration Commands					check-hostname(1M)

NAME

       check-hostname - check if sendmail can determine the system's fully-qualified host name

SYNOPSIS

	/usr/sbin/check-hostname

DESCRIPTION

       The  check-hostname  script  is a migration aid for sendmail(1M). This script tries to determine the local host's fully-qualified host name
       (FQHN) in a manner similar to sendmail(1M). If check-hostname is able to determine the FQHN of the local host, it reports  success.  Other-
       wise, check-hostname reports how to reconfigure the system so that the FQHN can be properly determined.

FILES

       /etc/hosts	     Host name database

       /etc/nsswitch.conf    Name service switch configuration file

       /etc/resolv.conf      Configuration file for name server routines
