How to lock multiple accounts?

To lock multiple user accounts in Linux, you can use a loop in the command line. Here’s a concise way to do it:

Using a Loop in Bash

You can create a list of usernames and then loop through that list to lock each account. Here’s an example:

for user in user1 user2 user3; do
    sudo passwd -l $user
done

Breakdown:

• for user in user1 user2 user3;: This initializes a loop that iterates over each username.
• sudo passwd -l $user: This command locks the password for each user in the list.

Example:

If you want to lock accounts for joker, batman, and superman, you would modify the command as follows:

for user in joker batman superman; do
    sudo passwd -l $user
done

Important Note:

Make sure to replace user1, user2, and user3 with the actual usernames you want to lock.
