In Linux Mint 21, services are used to manage and control various programs and processes that run in the background. These services are critical for the proper functioning of the system. Checking the status of a service can help identify any issues or errors that may be affecting it. This article will explore the different ways to check the status of a service in Linux Mint 21.

Method 1: Using the systemctl Command

The systemctl command is the most common and easiest way to check the status of a service in Linux Mint 21. The syntax for this command is as follows:

sudo systemctl status <service-name>

In this command, [service name] refers to the name of the service that we want to check the status of. For example, to check the status of the Apache web server, we would use the following command:

sudo systemctl status ssh

This command will display information about the status of the SSH service including whether it is running or not, any errors or issues that may be affecting it, and other useful information:

Method 2: Using the service Command

The service command is another way to check the status of a service in Linux Mint 21. The syntax for this command is as follows:

sudo service <service-name> status

In this command, [service name] refers to the name of the service that we want to check the status of. For example, to check the status of the SSH service, we would use the following command:

sudo service ssh status

This command will display information about the status of the SSH service, including whether it is running or not, any errors or issues that may be affecting it, and other useful information:

Method 3: Using the ps Command

The ps command can also be used to check the status of a service in Linux Mint 21. The syntax for this command is as follows:

ps -ef | grep <service-name>

In this command, [service name] refers to the name of the service that we want to check the status of. For example, to check the status of the MySQL service, we would use the following command:

ps -ef | grep ssh

This command will display information about the SSH service, including whether it is running or not, any errors or issues that may be affecting it, and other useful information.

Conclusion

Checking the status of a service is an important task for Linux Mint 21 users, as it can help identify any issues or errors that may be affecting the services running on our system. The systemctl, service command and the ps command is the most common and easiest way to check the status of a service in Linux Mint 21.
