Still not sure after reading the positings, if I need to append a line after a particular line, then how to do it?
For example -
Code:
My out-put is like this
$ p4 group -o lpth-everyone
# A Perforce Group Specification.
#
# Group: The name of the group.
# MaxResults: A limit on the results of operations for users in
# this group, or 'unlimited'. See 'p4 help maxresults'.
# MaxScanRows: A limit on the data scanned during operations for users
# in this group, or 'unlimited'. See 'p4 help maxresults'.
# Timeout: A time (in seconds) which determines how long a 'p4 login'
# session ticket remains valid (default is 12 hours).
# Subgroups: Other groups automatically included in this group.
# Users: The users in the group. One per line.
Group: lpth-everyone
MaxResults: unlimited
MaxScanRows: unlimited
Timeout: 43200
Subgroups:
Users:
aparna
hiqbal
kamalesh
nverma
rchitu
rmookherjee
rsarmiento
Now for example if I need to add "xxxxx" just below "nverma" then how to do it? Which means the output should be like this
Code:
My out-put required to be like this
$ p4 group -o lpth-everyone | <some unix stream appending operation>
# A Perforce Group Specification.
#
# Group: The name of the group.
# MaxResults: A limit on the results of operations for users in
# this group, or 'unlimited'. See 'p4 help maxresults'.
# MaxScanRows: A limit on the data scanned during operations for users
# in this group, or 'unlimited'. See 'p4 help maxresults'.
# Timeout: A time (in seconds) which determines how long a 'p4 login'
# session ticket remains valid (default is 12 hours).
# Subgroups: Other groups automatically included in this group.
# Users: The users in the group. One per line.
Group: lpth-everyone
MaxResults: unlimited
MaxScanRows: unlimited
Timeout: 43200
Subgroups:
Users:
aparna
hiqbal
kamalesh
nverma
xxxxx
rchitu
rmookherjee
rsarmiento
NOTE: I need to maintain the space before "xxxxx" as well.

group
GROUP(5) BSD File Formats Manual GROUP(5)NAME
group -- format of the group permissions file
DESCRIPTION
The group file /etc/group is the local source of group information. It can be used in conjunction with the Hesiod domain 'group', and the
NIS maps 'group.byname' and 'group.bygid', as controlled by nsswitch.conf(5).
The group file consists of newline separated ASCII records, usually one per group, containing four colon ':' separated fields. Each line has
the form:
group:passwd:gid:[member[,member]...]
These fields are as follows:
group Name of the group.
passwd Group's encrypted password.
gid The group's decimal ID.
member Group members.
The group field is the group name used for granting file access to users who are members of the group.
The gid field is the number associated with the group name. They should both be unique across the system (and often across a group of sys-
tems) since they control file access.
The passwd field is an optional encrypted password. This field is rarely used and an asterisk is normally placed in it rather than leaving
it blank.
The member field contains the names of users granted the privileges of group. The member names are separated by commas without spaces or
newlines. A user is automatically in a group if that group was specified in their /etc/passwd entry and does not need to be added to that
group in the /etc/group file.
Very large groups can be accommodated over multiple lines by specifying the same group name in all of them; other than this, each line has an
identical format to that described above. This can be necessary to avoid the record's length limit, which is currently set to 1024 charac-
ters. Note that the limit can be queried through sysconf(3) by using the _SC_GETGR_R_SIZE_MAX parameter. For example:
biggrp:*:1000:user001,user002,user003,...,user099,user100
biggrp:*:1000:user101,user102,user103,...
The group with the name ``wheel'' has a special meaning to the su(1) command: if it exists and has any members, only users listed in that
group are allowed to su to ``root''.
HESIOD SUPPORT
If 'dns' is specified for the 'group' database in nsswitch.conf(5), then group lookups occur from the 'group' Hesiod domain.
NIS SUPPORT
If 'nis' is specified for the 'group' database in nsswitch.conf(5), then group lookups occur from the 'group.byname' and 'group.bygid' NIS
map.
COMPAT SUPPORT
If 'compat' is specified for the 'group' database, and either 'dns' or 'nis' is specified for the 'group_compat' database in
nsswitch.conf(5), then the group file may also contain lines of the format
+name:*::
which causes the specified group to be included from the 'group' Hesiod domain or the 'group.byname' NIS map (respectively).
If no group name is specified, or the plus sign (``+'') appears alone on line, all groups are included from the Hesiod domain or the NIS map.
Hesiod or NIS compat references may appear anywhere in the file, but the single plus sign (``+'') form should be on the last line, for his-
torical reasons. Only the first group with a specific name encountered, whether in the group file itself, or included via Hesiod or NIS,
will be used.
FILES
/etc/group
SEE ALSO newgrp(1), passwd(1), su(1), setgroups(2), crypt(3), initgroups(3), nsswitch.conf(5), passwd(5), yp(8)HISTORY
A group file format appeared in Version 6 AT&T UNIX.
The NIS file format first appeared in SunOS.
The Hesiod support first appeared in NetBSD 1.4.
BUGS
The passwd(1) command does not change the group passwords.
