create 100 users in one go

Hi,

i have a situation,

i have to create 100 users in Linux with some password
can it be done in one go i tried newuser command but the home directory is not created for those users.

plus when i login for the first time into a server i got
EXECUTING /etc/profile ...
EXECUTING .profile ...
EXECUTING /xyz/abc/bin/setenv.ksh file ...

before the prompt. The above three lines shows that some kind of script was set to run when a user login for the first time that will create the home directory (if i am not guessing wrong)and never run if user login again.

how to do that any help appreciated.

You can find the answers on these pages.

http://linux.about.com/od/commands/l...l8_useradd.htm
Note that the second reference is for the useradd utility which is equivalent to newuser.

The -m option will create the home directory of the new user when used in either newuser or useradd.
The -D option will show you the default behavior of the newuser and the useradd utilities. You can also set the defaults using -D.

I don't know why you saw those messages. In the first two lines the login process was running normal login scripts. Evidently someone put those messages in those files. Also I suspect that in the third line the /xyz/abc was actually /usr/local which you could have included without any concern about security. In any case it appears to be something that someone else has set up for user login to set environment variables for the Korn shell. Those files are not intended to create the user's home directory. They are intended to create an environment for the user's process.

You should always include information about which Linux distribution you are using, including the version of that distribution, when you ask a question.

Code:

for user in `cat users.lst`
do
 sudo useradd -D $user

Not -D

That shows/sets defaults.

Speaking of which, the first thing I would do is to set the default of newuser to create the user account home directory without having to have that in the command parameters every time.

Code:

newuser -D -m

That would set the default behavior of newuser to create the new users' home directories without specifying that in each invocation of newuser.

Next, since we don't know the Linux distribution there is no reason to think that the original poster needs to use sudo. Evidently the original poster is able to create new users so he/she already knows about that or, more likely, is using the root account. Since this is in a business it is likely that they are using Red Hat or some more business oriented distribution where use of the root account is expected.

The original poster should tell us the Linux distribution asap since that will affect the details of the solution.

fyi:

Code:

[root@hyper ~]# uname -a -m -p
Linux hyper 2.6.34.7-66.fc13.x86_64 #1 SMP Wed Dec 15 07:04:30 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux
[root@hyper ~]# which newuser
/usr/bin/which: no newuser in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)

are you sure you dont mean useradd ?

Some distributions have newuser, some have useradd, some have both.

I guess previous posters mean the newusers command.
