systemctl:tldr:55f36

The command "systemctl ${select} ${unit}" is a systemd command used in Linux distributions to manage system services and units. Here is how the command is structured:

• "systemctl" is the basic command used to control systemd.
• "${select}" is a placeholder for an action you want to perform. It can be replaced with various options, such as "start", "stop", "restart", "enable", "disable", "status", etc., depending on the desired action.
• "${unit}" is a placeholder for the specific unit or service you want to act upon. It should be replaced with the name of the target unit or service you want to manage.

When executed, this command allows you to control the lifecycle of systemd units or services, including starting, stopping, restarting, enabling or disabling them, checking their status, and more. The actual values you substitute for "${select}" and "${unit}" determine the specific action and target unit or service.
