loginctl:tldr:facd6

The given command "loginctl show-user ${username} --property=${property_name}" is used to display specific properties of a user account in Linux systems using the "loginctl" utility.

Here's a breakdown of the command:

• "loginctl": It is a command-line tool used for managing user sessions and seats in Linux systems.
• "show-user": This subcommand is used to retrieve information about a specific user.
• "${username}": It represents the username or user ID for which you want to display the properties. You need to replace "${username}" with the actual username.
• "--property=${property_name}": This option allows you to specify a particular property to be displayed for the user account. You need to replace "${property_name}" with the actual property name.

For example, let's say you want to display the UID (User ID) property for a user named "john". The command would be:

loginctl show-user john --property=UID

This will display the UID of the user account named "john".
