Optimize code in single line
Dear team,


The below code is to check if number of lines in file greater than two then status is not ok else status is ok.
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:...

cmruncl

cmruncl(1m)															       cmruncl(1m)

NAME

       cmruncl - run a high availability cluster

SYNOPSIS

       cmruncl [-f] [-v] [-n node_name...]  [-t | -w none]

DESCRIPTION

       cmruncl causes all nodes in a configured cluster or all nodes specified to start their cluster daemons and form a new cluster.

       To  start  a  cluster,  a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configuration
       file. See access policy in cmquerycl(1m).

       This command should only be run when the cluster is not active on any of the configured nodes.  This command verifies the network  configu-
       ration  before  causing	the nodes to start their cluster daemons.  If a cluster is already running on a subset of the nodes, the cmrunnode
       command should be used to start the remaining nodes and force them to join the existing cluster.

       If node_name is not specified, the cluster daemons will be started on all the nodes in the cluster.  All  nodes	in  the  cluster  must	be
       available for the cluster to start unless a subset of nodes is specified.

   Options
       cmruncl supports the following options:

	      -f	Force cluster startup without warning message and continuation prompt that are printed with the -n option.

	      -v	Verbose output will be displayed.

	      -t	Test  only.  Provide  an assessment of the package placement without affecting the current state of the nodes or packages.
			The -w option is not required with the -t option as -t does not validate network connectivity, but assumes  that  all  the
			nodes can meet any external dependencies such as EMS resources, package subnets, and storage.

	      -n  node_name...
			Start the cluster daemon on the specified subset of node(s).

	      -w none	By default network probing is performed to check that the network connectivity is the same as when the cluster was config-
			ured. Any anomalies are reported before the cluster daemons are started. The -w none option  disables  this  probing.  The
			option should only be used if this network configuration is known to be correct from a recent check.

       RETURN VALUE
	      cmruncl returns the following value:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       Run the cluster daemon:

	      cmruncl

       Run the cluster daemons on node1 and node2:

	      cmruncl -n node1 -n node2
