enter image description hereIs there any way in which I can set the password for a newly created user account in AIX in a one line command? I don't want to give any prompt to the user. If there is a command, it should set the password to that user without asking anything on the screen. I need to use that command in another technology like Java/.Net. I need to create the accounts with password on a AIX machine at run time by executing one line of code where I can pass parameters. Suppose a user is giving a username in the text box of a Java application and in the background the command needs to be executed which will create the user accounts(with the password) at a remote AIX server. I am successful to add a user account, but setting the password is something where I am stuck.

You can use chpasswd

The chpasswd command administers users' passwords. The root user can supply or change users' passwords specified through standard input. Each line of input must be of the following format.

username:password Only root users can set passwords with this command.

Example 1:

echo username:password | chpasswd 

Example 2:

Also for security you can pass encrypted password to chpasswd

# Create Password in Encrpyted Form Using below command
# perl -e'print crypt("YourPassword", "salt")' ; echo -e

echo username:cryptedPass | chpasswd -e

  • Any idea how can I do the same thing for su command. Assume I have a root password and i want to change to root mode without giving any prompt so that i can run/invoke scripts from remote server using java or .net
