Ok Im trying too make this shell script create users from my text file, I also want to type in a password for the new users. So thay can make a uniq one themself after first logon.
This is how my text file looks like
This is what /etc/shadow looks like after running the script and what happens when I want to su to one of the new users.
I just dont understand why password is clear text in the shadow file.. As I think the problem lies there.
Help wanted any hints on whats wrong here?
Amen to cfajohnson, he is absolutely correct. Still, there are some additional points to a script creating users I'd like to stress:
1) Your script has several prerequisites which should be tested. You test for the script being run as as root and quite correctly so. Still there should be tested a lot of more conditions: is your file readable, is it in the expected format (how does your script behave if a line looks "user @host" instead of "user@host"? What will happen if the host specified doesn't exist?), etc.. Robust scripting always takes into account the probable typo and other typical errors.
1a) Corollary: most of these tests are very generic and could be done in (external) functions, for instance the test if it is run under root privileges. Presumably you have a lot of other scripts also depending on being run under root. Why don't you write a function "Being_Root()", which just tests this condition and gives back TRUE or FALSE. Accordingly with some other necessary prerequisites.
2) In your script no effort is undertaken to find (and correct) error conditions. Suppose you let your script run and one of the user accounts does already exist. How does your script react in this case? Terminate? Write a log entry? Issue an error message on the screen? How should your script deal with such a problem?
3) Your script gives back no return value. This way it will not be possible to include it into future scripts, because you don't get back any information if the run was successful or not. Well-behaved programs return an error code upon termination (usually: 0=ok, 1-255 several error conditions, like: input file missing, prerequisites not met, user already existing, ... )
Alright I have done som research and I found the solutions to the problem
regarding setting to a predefined password.
Added a line under the useradd loop.
Now to those things you mentiond bakunin I will attend them now that I have solved the main problem. Thanks for those exelent tips you gave me. And thanks alot for all the help so far. This was a very nice first encounter with this forum.
Next up is to expand the options abit. So you can chose account name instead of it09. return value's will be dealt with and if a user exists some kind of event will acur.
Thanks agen for all the help so far. Im learning as I go along and so far its been alot of fun.

Gurus,
I need to add a user to all the machines. I need a script to do this. I did one but it does not allow me to su to root within a ssh session i open. It exists saying su: Sorry. Please let me know how i can do it. I do not have the freedom of using sudo either.
