The command sudo chage --maxdays ${10} ${username} is used to change the maximum number of days between password changes for a specific user.

Here's a breakdown of the command:

• sudo is a command in Unix-like systems that allows a user with administrative privileges to execute a command as the superuser or another user.
• chage is a command used to modify the aging and expiration parameters of a user account in Linux.
• --maxdays specifies the aging parameter to be changed. In this case, it refers to the maximum number of days a user's password can remain unchanged before it must be changed.
• ${10} is a placeholder for a value. It represents the number of days you want to set as the maximum before a password needs to be changed. You need to replace ${10} with the actual value you desire.
• ${username} is another placeholder for a value. It represents the username of the user account you want to make changes to. You also need to replace ${username} with the actual username.

By executing this command with appropriate values, you can modify the aging parameters for a specific user account, setting the maximum number of days between password changes as desired.
