SHELL SCRIPT LINUX 使用用户输入设置密码

Question

I would like to set the password for the new account as the input (string) that the user entered. This does not seem to work. This is part of a larger script by the way, I only included the relevant parts to this issue.

So if I run the code I get the following error code: /create-user.sh: line 36: user3:hej: command not found.The line here is different as it is part of a larger script. the "hej" above is what I entered as the input to password when I ran the code. I guess shell thinks "hej" is supposed to be a command, but it should be a string for the password. To clarify, hej should be the password.

#!/bin/bash

# Get the username (login).
read -p "Please enter a username: "  username

# Get the password.
read -p "Please enter an initial password: " password

# Create the account.
useradd "$username"

# Set the password.
chpasswd | "$username":"$password"

Answer 1

$username:$password should be the input to the chpasswd command. You're piping the output of chpasswd to a command formed from that. Since the username:password isn't the name of a command, you get an error.

What you want is:

chpasswd <<< "$username:$password"
