creating users using VIPW.

[senthil_kumar_1]

Hi

how to create / handle the users using vipw.

[Suraj K Sankari]

hi,

vipw edits the password file while setting the appropriate locks, and does any necessary processing after
the password file is unlocked. If the password file is already being edited, you will be told to try again later.
The vi editor is used unless the environment variable EDITOR indicates an alternate editor. vipw
performs a number of consistency checks on the password entry for root, and does not allow a password
file with an incorrectly formatted root entry to be installed.

is vipw is a editor like vim in linux?

can we use vipw to edit any file?

pls explain me how to use vipw to addusers in /etc/passwd.

Hi Senthilkumar,

VIPW is noting but edit the /etc/passwd file using vi.
The advantage of using vipw is that only one person can edit at one time. So that it will avoid file corruption.

Using vipw you can directly edit uid/gid/comment/shell/login directory instead of using usermod.

You can also create a new user by putting new entry in /etc/passwd. But note that you need to change the password using passwd command. Also you need to manually copy the startup files from skelton directory.

>>can we use vipw to edit any file?<<

No. You can't edit any other file.

>>pls explain me how to use vipw to addusers in /etc/passwd.<<

Just add another line like any other user in /etc/passwd.

See man vipw for more details.

can we use vi to edit /etc/passwd?

but if we use vipw to edit /etc/passwd then no one can edit that file "/etc/passwed" at same time.

>can we use vi to edit /etc/passwd?

Why? vipw does that for you.

>but if we use vipw to edit /etc/passwd then no one can edit that file "/etc/passwed" at same time.

That's correct, only one use can be modifying /etc/password at a time.

[Dennis Handly]

That's:
That's correct, only one user can be modifying /etc/passwd at a time. Other users can still read it.

Hello Senthil

vipw inshore that the modification is doing by only one user â ¦

Well you can copy one of the string from your password file and edit according to your user ,then edit the password file with vipwâ ¦

If your system is trusted the execute pwconv to update tcb file as well

Hi Senthil,

Yes you can used vi to edit the /etc/passwd file but in my concerned it better to use vipw instead of vi.

To create new account using vi

If you are using vi to create a account then you need to do this steps
1.create a home directory for user i.e. newuser
2.copy all file from /etc/skel into /home/newuser
3. open /etc/passwd file into vi
4.copy paste last line
5.edit username:uid:gid:comments:homedirectory:shell
6.save the file check with pwck command
7.change the passwd for newuser
8.passwd newuser

HP Guru's please correct me if I miss any step's
