Howsoever, "But its not working" is not an utmost good starting point for an analysis. You should describe exactly what in the current behaviour doesn't fulfill your needs or what the error message(s) be.
I guess the target string is appended to the entry, not replacing the last field's value? So you should provide that value, so the substitute has something to replace:
On top, it is good practice to anchor the search pattern (if possible), here to the start-of-line, to be safe of false positives.
I have to replace a field in one file with a field from other file.
I came across this awk command to replace a field with one string
nawk -F'|' -v OFS='|' '$2="replace"' temp2 > temp3
I need to have something like cut -f2 -d "|" temp1 (a field from other file) instead of 'replace'

Howdy.
I know this is most likely possible using sed or awk or grep, most likely a combination of them together, but how would one go about running a grep like command on a file where you only try to match your pattern to the second field in a line, space delimited?

posix_getpwnam
POSIX_GETPWNAM(3) 1 POSIX_GETPWNAM(3)posix_getpwnam - Return info about a user by usernameSYNOPSIS
array posix_getpwnam (string $username)
DESCRIPTION
Returns an array of information about the given user.
PARAMETERS
o $username
- An alphanumeric username.
RETURN VALUES
On success an array with the following elements is returned, else FALSE is returned:
The user information array
+--------+---------------------------------------------------+
|Element | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| name | |
| | |
| | The name element contains the username of the |
| | user. This is a short, usually less than 16 char- |
| | acter "handle" of the user, not the real, full |
| | name. This should be the same as the $username |
| | parameter used when calling the function, and |
| | hence redundant. |
| | |
|passwd | |
| | |
| | The passwd element contains the user's password |
| | in an encrypted format. Often, for example on a |
| | system employing "shadow" passwords, an asterisk |
| | is returned instead. |
| | |
| uid | |
| | |
| | User ID of the user in numeric form. |
| | |
| gid | |
| | |
| | The group ID of the user. Use the function |
| | posix_getgrgid(3) to resolve the group name and a |
| | list of its members. |
| | |
| gecos | |
| | |
| | GECOS is an obsolete term that refers to the |
| | finger information field on a Honeywell batch |
| | processing system. The field, however, lives on, |
| | and its contents have been formalized by POSIX. |
| | The field contains a comma separated list con- |
| | taining the user's full name, office phone, |
| | office number, and home phone number. On most |
| | systems, only the user's full name is available. |
| | |
| dir | |
| | |
| | This element contains the absolute path to the |
| | home directory of the user. |
| | |
| shell | |
| | |
| | The shell element contains the absolute path to |
| | the executable of the user's default shell. |
| | |

EXAMPLES
Example #1
Example use of posix_getpwnam(3)
<?php
$userinfo = posix_getpwnam("tom");
print_r($userinfo);
?>
The above example will output something similar to:
Array
(
[name] => tom
[passwd] => x
[uid] => 10000
[gid] => 42
[gecos] => "tom,,,"
[dir] => "/home/tom"
[shell] => "/bin/bash"
)
