switching user

Hi all,
I've been trying to make a small bash script to create a user and then to switch to the new user. But, I cannot giving the password when the script executes the command

I'm trying this:

Code:

#!/bin/bash 
user=test
pass=xxxx
dir=/var/www/mydir
group=adm
bash=/bin/bash

sudo useradd -d "$dir" -s "$bash" -g "$group" -m $user
echo "$user:$pass" |sudo chpasswd 
echo -e "El usuario ha sido creado con exito...\n"
echo -e "$pass\n" | su - $user > /dev/null 2>&1 && echo -e "\nSwitching user completed... You're $user"
# ??????

I need switch user inside de bash script, but I don't know how... I hope you can help me...

Thanks in advance.

Thanks for answer ...
I try that but... I running script as root. When I run sudo su - user or su - user asks me the user's password and there is where I have the problem. How can I make the password take it to a variable and not wait keyboard input?

Thanks for your help!

If you are root, then you should be able to fully configure the user's credentials and to reach right in to the user's home directory and set that up, too. Just be sure to chown everything to the user's owner-id and group-id so that they "belong to him." (Unless you want to exercise your godly prerogatives to put something there that doesn't "belong to him.")

Eduard..

1) You can't redirect 'su - ' to /dev/null.. this won't work..
2) The script won't continue to execute after the user is switched.. So the portion [/code]echo -e "\nSwitching user completed... You're $user"[/code]
will be executed after you logout
3) 'su - ' will only accept passwords from terminal devices.. You can't pipe the password to it.. However, if the script is runned as root it should not ask you for the password
