Ok, what is $i? Is this script really large, or would it be appropriate to post all of it here? What I'm trying to get at is that if you can just gather the data you want, the output won't look so bad. From what I see so far, it looks like your getting too much of something (blank lines) when defining variables.

cmscancl
cmscancl(1m) cmscancl(1m)
NAME
cmscancl - gather system configuration information from nodes with Serviceguard installed.
SYNOPSIS
cmscancl [-n node_name]... [-s|-o output_file]
DESCRIPTION
cmscancl is a configuration report and diagnostic tool intended only for use by HP Support Personnel. It gathers system software and hard-
ware configuration information from a list of nodes, or from all the nodes in a cluster. The information that this command displays
includes LAN device configuration, network status and interfaces, file systems, LVM configuration, link-level connectivity (HPUX only),
IPv4/IPv6 connectivity, and the data from the binary cluster configuration file. This command can be used as a troubleshooting tool or as
a data collection tool.
This command is a Perl script which gathers system configuration information by executing various OS commands or tools. It uses the cmexec
command to gather information from remote nodes.
The -n option can be used to specify a list of nodes to be scanned, the nodes to be scanned do not need to be a member of a cluster. If
the -n option is not specified, it will scan all the nodes in the local cluster.
By default, the output of this command will go to the file /tmp/scancl.out. If the file /tmp/scancl.out already exists, the old file will
be saved in /tmp/scancl.out.old.
The -o option can be used to redirect output to a specified output file. If the -o option is not specified, output will go to the default
output file /tmp/scancl.out.
The -s option can be used to direct all output to the screen, instead of to an output file.
Options
cmscancl supports the following options:
-n node_name... Specify the node(s) to be scanned. If this option is not specified and there is a cluster configured, all the
nodes in the cluster will be scanned. If this option is not specified and there is no cluster configured, only the
local node will be scanned.
-o output_file Write configuration information to a specified output file. If this option is not specified, the information will
be directed to stdout.
-s Display the configuration information to the screen only. This option cannot be used in conjunction with the -o
option.
The output from this command contains the following information:
LAN device configuration (On HP-UX, output from lanscan; On Linux, output from ifconfig)
network status and interfaces (output from netstat)
file systems (output from mount)
LVM configuration (contents of /etc/lvmtab file)
LVM physical vg information (contents of /etc/lvmpvg file)
link-level connectivity (HP-UX only)
(output from linkloop)
IPv4/IPv6 connectivity (results from ping (and ping6 on Linux))
binary configuration file data
(output from cmviewconf)
RETURN VALUE
cmscancl returns the following value:
0 Successful completion.
1 Command failed.
EXAMPLES
To gather the configuration information from node1 and node2 and to save the output in file /tmp/scancl.log:
cmscancl -n node1 -n node2 -o /tmp/myscancl.log
To gather the configuration information from all the nodes in the cluster and save the output to the file: /tmp/scancl.log:
cmscancl -o /tmp/myscancl.log
To gather the configuration information from all the nodes in the cluster and display the output on the screen:
cmscancl -s
To gather the configuration information from all the nodes in the cluster and save the output to the file /tmp/scancl.out:
