I need to optimize it in single line code in awk or sed if possible.


Pls help


Code:
cat LOTCCLUS_stat
count=`cat LOTCCLUS_stat | wc -l`
if [[ $count -gt 2 ]]; then

echo "##### THE LOTC cluster state IS NOK ##########"
else
echo "##### THE LOTC cluster state IS OK  ##########"
fi


The file as below

Quote:
cat LOTCCLUS_stat
Checking LOTC cluster state:...

clsetup

clsetup(1CL)						 Sun Cluster Maintenance Commands					      clsetup(1CL)

NAME

       clsetup - configure Sun Cluster interactively

SYNOPSIS

       /usr/cluster/bin/clsetup  -V

       /usr/cluster/bin/clsetup  -?

       /usr/cluster/bin/clsetup  [-f logfile]

DESCRIPTION

       The  clsetup  command  provides the following configuration capabilities, depending on what state the cluster is in when you issue the com-
       mand. The user must be superuser to run this command.

       This command has no short form.

	   o	  When you run the clsetup command at post-installation time, the command performs initial setup tasks, such as configuring quorum
		  devices  and	resetting  the installmode property. If you deselected automatic Quroum Configuration when you created the cluster
		  using either scinstall or the cluster create command, then you must run the clsetup command immediately after  the  cluster  has
		  been installed. Ensure that all nodes have joined the cluster before you run the clsetup command and reset the installmode prop-
		  erty.

		  If you used automatic quorum configuration when you created the cluster, you do not need to run the clsetup command after  clus-
		  ter installation. The automatic quorum configuration feature also resets the installmode property of the cluster.

		  You can issue this form of the clsetup command from any node in the cluster.

	   o	  When you run the clsetup command during normal cluster operation, the scsetup command provides an interactive, menu-driven util-
		  ity to perform cluster configuration tasks. The following are some of the cluster components which this utility administers:

	       o      Quorum

	       o      Resource groups

	       o      Data services

	       o      Cluster interconnect

	       o      Device groups and volumes

	       o      Private hostnames

	       o      New nodes

	       o      Other cluster properties
	   You can issue this form of the clsetup command from any node in the cluster.

	   o	  When you run the clsetup command from a node that is in noncluster mode, the clsetup command provides a menu-driven utility  for
		  changing and displaying the private IP address range.

		  You must reboot all nodes into noncluster mode before you start this form of the clsetup utility.

OPTIONS

       The following options are supported:

       -?
       --help

	   Prints help information for the command.

       -f logfile
       --file logfile

	   Specifies  the  name of a log file to which commands can be logged. If this option is specified, most command sets generated by clsetup
	   can br run and logged, or just logged, depending on user responses.

       -V
       --version

	   Prints the version of the command set. No command line processing will be performed and the command will not enter into its interactive
	   menu.
