Also thanks a lot for unix forum guys "you ppl rock!!!"
FYI, i was trying to search for this code since all the weekend and went through sed manual "http://www.grymoire.com/Unix/Sed.html" sub topic (/1, /2, etc. Specifying which occurrence) however was unlucky in trying all the trial and error method.
Also Summer could you please explain me the code you have written so that i can understand it in a better way.
Again thanks a lot and you can close this thread.
Thanks

vzlist
vzlist(8) Containers vzlist(8)
NAME
vzlist - show various information about containers
SYNOPSIS
vzlist [-a | -S] [-n] [-H] [-o name[,name...] | -1] [-s [-]name] [-h pattern] [-N pattern] [-d pattern] [CTID [CTID ...]]
vzlist -L | --list
vzlist --help
DESCRIPTION
This utility is used for listing containers and their parameters. By default only running containers are listed. If one or more CTIDs are
specified, only specified containers are displayed.
For the fields that can have many values (e.g. ip), all the values are displayed only for the last (i.e. leftmost) column; otherwise, only
the first value is shown.
OPTIONS
-a, --all
List all containers.
-S, --stopped
List only not running containers (including the ones with status shown as mounted or suspended).
-n, --name
Display container names instead of hostnames.
-H, --no-header
Suppress displaying the header row.
-o, --output field[,field...]
Display only the specified fields (see Standard fields subsection below).
-1 Synonym for -H -octid, i.e. only show container IDs, one per line.
-s, --sort [-]field
Sort by the value of field (possible arguments are the same as for -o). The - before the field name means sorting in the reverse
order.
Output filters
List of CTs can be further filtered using the following options. For patterns one can use the same wildcards as in shell (i.e. *, ?, and
[]). Note: to avoid expansion of wildcards by the shell, one have to escape the pattern by either putting it into single quotes (like
'a*a') or by adding a backslash before the wildcard character (like a*a).
-h, --hostname pattern
List only containers whose hostnames matches the pattern.
-N, --name_filter pattern
List only containers whose names matches the pattern.
-d, --description pattern
List only containers with descriptions matching the pattern.
Possible fields
-L, --list
list all available format specifiers that can be used for both output (-o, --output) and the sorting order (-s, --sort).
For the user beancounter fields, if suffix is not specified, current usage (a.k.a. "held") value is show. One can also use the fol-
lowing suffixes:
.m maxheld
.b barrier
.l limit
.f fail counter
For the disk quota fields, if suffix is not specified, current usage is shown. One can also use the following suffixes:
.s soft limit
.h hard limit
EXAMPLES
vzlist -o ctid,kmemsize,kmemsize.l -s kmemsize
Show CTIDs, kmemsize usage, and kmemsize limit for all running containers, sorted by the kmemsize usage.
EXIT STATUS
Returns 0 upon success.
