how to assign password for a user in shell script

mtest · 10-16-2003, 06:34 AM

The problem is to create a user and assign a password for that user from the shell script instead of at prompt.
when i create a shell file
and i have typed
useradd xyz
passwd xyz pqr
and when i run the shell by giving bash file name, the new user is created but the password is not assigned, it is treating pqr is also a username

please tell me how to assign password for a user from the shell script

thanks in Advance

You can't. There's no way to do that using an unaltered 'adduser' within a bash script.

You learn something new everyday:

Code:

#!/bin/bash
useradd -p <password> <username>

mtest · 10-16-2003, 07:44 AM

I tried executing

useradd -p <password> <username>

but it doesn't work.

please reply

You need to replace '<password>' with the password to be used, and the <username> with the username to be used.

Code:

#!/bin/bash
useradd -p 'G7*h!&dW@' mtest

Be sure to put strong quotes '' around the password.

I tried same thing which you have mentioned, it doesnt show error at $prompt, when I try login with username(mtest) and when I enter the paswword in the password window. it is not allowing to login. but user is cerated without password,( I tried as root to assign, it that user(mtest )already exists).

I can't get 'useradd' to encrypt the password, whatever password you enter can be seen literally when you open '/etc/shadow'....This mean's that 'login' would encyrpt it, and the password would never be right, I guess this program just doesn't work as specified yet, mabey somebody should work on it.

I wrote the script, but got the idea from the site above in which I learned about 'openssl'.

Code:

#!/bin/bash
#enter password and username [adduser.sh '<password>' <username>]
PASS=$(openssl passwd -1 "$1")

useradd -p "$PASS" "$2"
exit 0
