UNIX for Dummies Questions & Answers

Hello-
I am new to UNIX (about 1 month to be exact) and have been trying to construct a script to create users and passwords using expect. I have the basic script worked out, which includes creating the user and password, but would like for this to be automated a little more and have it read a list of users from a separate file along with the passwords and then create them based on that separate list.

Here is what I have worked out so far:

# cat testusercreate.sh
#!/usr/bin/expect
# Script for automating creation of user names

spawn ssh approd
expect "root@approd's password:"
send "password2\r"
expect "#"
send "mkgroup test\r"
expect "#"
send "useradd -g test alpha\r"
expect "#"
send "passwd alpha\r"
expect "alpha's New password:"
send "test1\r"
expect "Enter the password again:"
send "test1\r"
expect "#"
send "exit\r"
expect closed
exit 0

Any help would be greatly appreciated

Thanks,
Marty

Create a ssh key-pair for easier login. Then you can use the more compact

Code:

ssh root@approd "mkgroup test ; useradd -g ${group} ${user} ; passwd -o ${passwd}"

To go through the list, read up on read and your shells control statements (for/while)

Thanks so much for your assistance Pludi. That does help me shorten it. You said I should read up on "read and shells control statements". Do you have any helpful links?

again thanks for the assistance.
