Hi people, i'm in need of serious help asap in regard of creating multiple user account like for example of 100 user account using loops in a script to create. Can anyone help me asap. Thanks.

Well, I'm not sure anyone here is willing to actually do the work for you, since linuxquestions is here to answer questions.

Maybe you could show us the script you have so far, and ask us questions about where you got stuck.

Hope this helps.

for i in `seq 1 100`;
do
useradd user$i
done

for example something like this, would be able to work am i right ? In this case the password after that should i go yast and set something on it, but end of the day i just hope to know if this above code do really work, thanks

There's some good stuff about shell scripting, among other things, at linuxcommand.org so read there if you are unsure about commands. Basically to add a user to the system you can use ready scripts (can be tricky to script to use a script to add the user) or just modify three files: /etc/passwd, /etc/shadow and /etc/group (first one: user information, NO password, second: encrypted password and some information, third: group information). The syntax in the files is important. Basically to add users you'll have to add new lines to the files (easy) with two or three fields edited, the others may remain as they are (days before password expiration, days after Epoch, ...) If you know the syntax it should be easy enough, and the syntax can be obtained from manpages for example (man /etc/passwd). Passwords are set after this, using passwd for example, but that's another thing. I'm not sure if some of the Big distributions handle users in a complex way today, they shouldn't, but then again init scripts are handled in a complex way often (except in Slackware). If everything is all right, you should be able to easily script something that alters the three files and adds the users. For gods sake, first test it with one and not 100 accounts, and better yet don't use the original files at first, but do it with some testfiles like ~/passwd, ~/shadow, ~/group to see the effects.

I too doubt if anyone is willing to write the script for you (I would, if I had time heh) but surely you'll get help if you ask. If you have a partially ready or started-out script, post it here if you like, you'll get comments and suggestions.

What he said.

Do you have the list of usernames/passwords in a file? If so, check whether you have the newusers command installed - the man page gives details on using it.

ar sorry guys i was busy with other project for the past few days thus unable to reply, anyway is there any sites you guys can intro me for me to learn more about adding this 1 to 100 users thing, because i also need to know how to set them into the correct groups and add password to each user, urgent help needed please guide me guys, would be very grateful about it.

i do have all the user in a single file, but i think is that i tried to run that more than once then the system tells me that the file already existed or something like that, but right now the problem is that i need to know more than that, i need to know how to set password for each user also, can anyone give me a better idea about it ?

Slow down and re-read post #4 in this thread. You may be in a hurry, but you have some reading ahead of you.
