How to Check Service Status on Linux: Simple Commands

To check the status of a service on Linux, use the systemctl status servicename command on systems with systemd. On older systems, use service servicename status to see if the service is running.

Syntax

There are two common commands to check service status on Linux:

• systemctl status servicename: Shows detailed status of the service using systemd.
• service servicename status: Works on older init systems to show if the service is running.

Replace servicename with the actual name of the service you want to check.

bash

systemctl status servicename

service servicename status

Example

This example checks the status of the ssh service using systemctl. It shows if the service is active and running.

bash

systemctl status ssh

Output

● ssh.service - OpenBSD Secure Shell server
   Loaded: loaded (/lib/systemd/system/ssh.service; enabled; vendor preset: enabled)
   Active: active (running) since Fri 2024-06-14 10:00:00 UTC; 1h 30min ago
     Docs: man:sshd(8)
           man:sshd_config(5)
 Main PID: 1234 (sshd)
    Tasks: 1 (limit: 4915)
   Memory: 2.0M
   CGroup: /system.slice/ssh.service
           └─1234 /usr/sbin/sshd -D

Common Pitfalls

Common mistakes when checking service status include:

• Using service on systems that use systemctl, which may not work or show limited info.
• Not running the command with sufficient permissions; some services require sudo.
• Misspelling the service name, which leads to errors or no output.

Always verify the service name and use sudo if needed.

bash

service ssh status

sudo systemctl status ssh

Quick Reference

Command	Description
systemctl status servicename	Show detailed status of a service on systemd systems
service servicename status	Check service status on older init systems
sudo systemctl status servicename	Run with admin rights if permission denied
systemctl is-active servicename	Show if service is active (running) or not

Key Takeaways

Use 'systemctl status servicename' to check service status on modern Linux systems.

Use 'service servicename status' on older Linux systems without systemd.

Run commands with 'sudo' if you get permission errors.

Always use the correct service name to get accurate status.

Use 'systemctl is-active servicename' for a quick active/inactive check.
