Hello, was looking for some help on extracting a field from the passwd file.
So far I have made a copy of the passwd file and changed my rights so I can edit it. Every user's password is coded as an :x:, and my goal was to change that x to a blank, and then try to extract any user with that field... (2 Replies)

Hi,
I have a Solaris 10 box where password aging is not functioning properly. Using the passwd command with the -l or -u options causes the lastchg field in the /etc/shadow file to be modified.

master.passwd
PASSWD(5) BSD File Formats Manual PASSWD(5)NAME
passwd, master.passwd -- format of the password file
DESCRIPTION
The /etc/passwd file is a legacy BSD 4.3 format file. It is mostly unused, but is updated by some utility programs. Its format is similar
to the /etc/master.passwd file, except that it does not contain the class, change, and expire fields described below.
The /etc/master.passwd file comprises newline separated records, one per user. Each line contains ten colon (``:'') separated fields. These
fields are as follows:
name User's login name.
password User's encrypted password.
uid User's id.
gid User's login group id.
class User's general classification (unused).
change Password change time.
expire Account expiration time.
gecos User's full name.
home_dir User's home directory.
shell User's login shell.
The name field is the login used to access the computer account, and the uid field is the number associated with it. They should both be
unique across the system (and often across a group of systems) since they control file access.
While it is possible to have multiple entries with identical login names and/or identical user id's, it is usually a mistake to do so. Rou-
tines that manipulate these files will often return only one of the multiple entries, and that one by random selection.
The login name must never begin with a hyphen (``-''); also, it is strongly suggested that neither upper-case characters or dots (``.'') be
part of the name, as this tends to confuse mailers. No field may contain a colon (``:'') as this has been used historically to separate the
fields in the user database.
The password field is the encrypted form of the password. If the password field is empty, no password will be required to gain access to the
machine. This is almost invariably a mistake. Because these files contain the encrypted user passwords, they should not be readable by any-
one without appropriate privileges.
The group field is the group that the user will be placed in upon login. Since this system supports multiple groups (see groups(1)) this
field currently has little special meaning.
The class field is currently unused.
The change field is the number in seconds, GMT, from the epoch, until the password for the account must be changed. This field may be left
empty to turn off the password aging feature.
The expire field is the number in seconds, GMT, from the epoch, until the account expires. This field may be left empty to turn off the
account aging feature.
The gecos field normally contains the user's full name. Note that Mac OS X differs from some other operating systems, where the gecos field
may contain other comma-separcted information about the user.
The home_dir field is the user's home directory. This is the full path name where the user will be placed on login.
The shell field is the command interpreter the user prefers. If there is nothing in the shell field, the Bourne shell (/bin/sh) is assumed.
INTERACTION WITH DIRECTORY SERVICES
Processes generally find user records using one of the getpwent(3) family of functions. On Mac OS X, these functions interact with the
DirectoryService(8) daemon, which reads the /etc/master.passwd file as well as searching other directory information services to find user
accounts.
