userhelper − A helper interface to pam.
userhelper [ -c ] [ −f full-name ] [ −o office ] [ −p office-phone ] [ −h home-phone ] [ −s shell ] [ username ]
NOTE this program is NOT intended to be run interactively. If you want to change this information on the command line use passwd(1), chfn(1), or chsh(1).
This program provides a basic interface to change a user’s password, gecos information, and shell. The main differnce between this program and it’s traditional equivilents is that prompts come out on standard out to make it easy for a GUI program to interface it as a child process.
The output is
in the form of:
<number> <string>
Where the number is the type of prompt returned from pamlib, and the string is the prompt to give the user.
The prompt numbers are as follows:
|
1 |
Prompt with visible input. |
|||
|
2 |
Prompt with invisible input. |
|||
|
3 |
Informational message. |
|||
|
4 |
Error message. |
|
-c |
Change the current user’s password. Note that this option cannot be used with any of the other options. This is due to the limitation in the interface to pamlib. | ||

|
-o |
Specify a new Office. | ||
|
-p |
Specify a new Office Phone. | ||
|
-h |

|
