Systemctl is a command-line tool used to manage systemd, which is the system and service manager for Linux operating systems. With systemctl, you can start, stop, enable, and check the status of services. It's essential for maintaining and managing system services efficiently.
Here's an example of how to use some common systemctl commands:
# Check the status of a service (e.g., sshd)
systemctl status sshd
# Start a service (e.g., sshd)
sudo systemctl start sshd
# Stop a service (e.g., sshd)
sudo systemctl stop sshd
# Enable a service to start on boot (e.g., sshd)
sudo systemctl enable sshd
# Disable a service from starting on boot (e.g., sshd)
sudo systemctl disable sshd
