Could someone tell me the command to find out the OS version which will give 12 character not the 9 characters(which is usually machine id).

Please have a look at below examples. Why do these 3 sed commands deliver the same result? Especially, why are there 4 "x" in the result instead of 3?
1.
echo "abc" | sed 's/d*/x/g'
xaxbxcx
2.
echo "abc" | sed 's/d*/&x/g'

groupadd
groupadd(1M) System Administration Commands groupadd(1M)NAME
groupadd - add (create) a new group definition on the system
SYNOPSIS
/usr/sbin/groupadd [ -g gid [-o]] group
DESCRIPTION
The groupadd command creates a new group definition on the system by adding the appropriate entry to the /etc/group file.
OPTIONS
The following options are supported:
-g gid Assigns the group id gid for the new group. This group id must be a non-negative decimal integer below MAXUID as defined in
/usr/include/sys/param.h. The group ID defaults to the next available (unique) number above the highest number currently assigned.
For example, if groups 100, 105, and 200 are assigned as groups, the next default group number will be 201. (Group IDs from
0-99 are reserved by SunOS for future applications.)
-o Allows the gid to be duplicated (non-unique).
OPERANDS
The following operands are supported:
group A string consisting of characters from the set of lower case alphabetic characters and numeric characters. A warning message will
be written if the string exceeds MAXGLEN, which is usually set at eight characters. The group field must contain at least one
character; it accepts lower case or numeric characters or a combination of both, and must not contain a colon (:) or NEWLINE.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
2 Invalid command syntax. A usage message for the groupadd command is displayed.
3 An invalid argument was provided to an option.
4 The gid is not unique (when -o option is not used).
9 The group is not unique.
10 The /etc/group file cannot be updated.

groupadd only adds a group definition to the local system. If a network name service such as NIS or NIS+ is being used to supplement the
local /etc/group file with additional entries, groupadd cannot change information supplied by the network name service. However, groupadd
will verify the uniqueness of group name and group ID against the external name service.
