thanks for your input though. If you don't mind explaining, could you go into detail of the structure of this statement and why you did that.

I'm still trying to figure out the placement/requirement/caveats of (), [],{}, of which you're only using parentheses here. Hopefully you understand what I'm asking.

Am I right to assume the single quotes are to group the commands together or are they dual purpose in order to execute commands within the awk command as well as grouping the contents. kind of like sub-shell execution?

I'm familiar with using the forward-slash to initiate a search as within vi, less environments, then you're using the back-slash to escape the following forward-slash metacharacter which is a part of the search string...what's the last forward-slash's purpose in that statement? Also, the open-close parentheses around the integer and column id? If you have reference material, I'll gladly take as response.

lufslist

lufslist(1M)															      lufslist(1M)

NAME

       lufslist - list configuration of a boot environment

SYNOPSIS

       /usr/sbin/lufslist [-l error_log] [-o outfile] BE_name [-X]

DESCRIPTION

       The  lufslist  command  is  part  of  a	suite  of commands that make up the Live Upgrade feature of the Solaris operating environment. See
       live_upgrade(5) for a description of the Live Upgrade feature.

       The lufslist command lists the configuration of a boot environment (BE). The output contains the disk  slice  (file  system),  file  system
       type, and file system size for each BE mount point.

       The following is an example of lufslist output.

       # lufslist BE_name
       Filesystem		 fstype       size(Mb) Mounted on
       ------------------------------------------------------------------
       /dev/dsk/c0t0d0s1	 swap		512.11 -
       /dev/dsk/c0t4d0s3	 ufs	       3738.29 /
       /dev/dsk/c0t4d0s4	 ufs		510.24 /opt

       File  system  type  can	be  ufs,  swap,  or vxfs, for a Veritas file system. Under the Filesystem heading can be a disk slice or a logical
       device, such as a disk metadevice used by volume management software.

       The lufslist command requires root privileges.

OPTIONS

       The lufslist command has the following options:

       -l error_log

	   Error and status messages are sent to error_log, in addition to where they are sent in your current environment.

       -o outfile

	   All command output is sent to outfile, in addition to where it is sent in your current environment.

       -X

	   Enable XML output. Characteristics of XML are defined in DTD, in /usr/share/lib/xml/dtd/lu_cli.dtd.<num>, where <num>  is  the  version
	   number of the DTD file.

OPERANDS

       BE_name

	   Name of the BE for which file systems are to be reported. You cannot specify a BE that is involved in another Live Upgrade operation.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.

FILES

       /etc/lutab

	   list of BEs on the system

       /usr/share/lib/xml/dtd/lu_cli.dtd.<num>

	   Live Upgrade DTD (see -X option)
