OpenSuSe useradd help

or why developers should not add nonsense options

This weekend I had to do some things on an OpenSuSe 10.3 server (some dirty migration of a Zope/PostgreSQL webapp). One of the tasks I had to do involved the creation of some user accounts. Yes, I know there is YasT in the SuSe world, but something like the Slackware's adduser script should be a better tool.

In OpenSuSe, there is a man page for adduser but calling man adduser sends you to useradd(8)... ok, (I thought), "useradd should be a similar tool".

So I tried useradd directly, expecting a help message:

server:~ # useradd
useradd: Too few arguments.
Try `useradd --help' or `useradd --usage' for more information.
server:~ #

Nice, there was a message, and it pointed me to two different options to get more info. I decided to try --usage (the tipical shorter version of the help) but, guess what?

server:~ # useradd --usage
Usage: useradd ...
server:~ #

WTF! That is a really useful message! (of course --help has the full help, but anyway...)

Re: OpenSuSe useradd help

in contrast in OpenBSD, usage is printed by default:
~$ useradd
usage: useradd -D [-b base-directory] [-e expiry-time] [-f inactive-time]
[-g gid | name | =uid] [-k skel-directory] [-L login-class]
[-r low..high] [-s shell]
useradd [-mov] [-b base-directory] [-c comment] [-d home-directory]
[-e expiry-time] [-f inactive-time]
[-G secondary-group[,group,...]] [-g gid | name | =uid]
[-k skel-directory] [-L login-class] [-p password] [-r low..high]
[-s shell] [-u uid] user
~$

Re: OpenSuSe useradd help

And you have a user-friendly adduser script too, that asks you for every piece of information needed in order to create a user... ;D

I don't understand why some linux distributions do not have such script, it is very useful (even more if you compare it to the full-bloated YasT tool, for example)
