Change password with out any prompt, How ?
 
Hi,

I want to create the users and set the passwords to 'eW4hNXNIc' for all new users.I don't want any prompts or confirmation when creating the users.

Is there a way to achieve this in REDHAT LINUX ? Can some one help?


regards,
aparna.

You can do the following when using RedHat:
Code:
# create user the normal way:
$ /usr/sbin/useradd -c "Comment goes here" -m -d /home/username -s /bin/bash -u 500 -g 500 username

# set password:
/bin/echo "very_secret" | passwd --stdin username
To my knowledge the password --stdin username construct is only supported in RedHat and RedHat based distro's.

Along the same lines of your very first post here last year:

You've been here a year now, and you seem to only want us to look things up for you.

The below command works fine in my Dedian & Ubuntu based Operating system

echo "username:password" | chpasswd

I've seen cases where that kind of thing fails due to stdin not being a tty (picky program reading for the password). In such cases I've usually found that the "script" program (and a delay in sending in the password) works. The "expect" program (or "pexpect" with a Python script) can also help.
