How to view and stop Linux-initiated services

1. View Linux-initiated services

Chkconfig--list queries all currently running Services Chkconfig--list ATD Query ATD The current status of the service 2. Stop all services and do not start the next time the system starts, as follows: Chkconfig--levels 12345 NetworkManager off if you want to see the service that is currently running, use the following statement to filter Chkconfig--list |grep on 3. If you just want the current setting to be valid, it won't take effect after the system restarts. You can use the following command to stop the service for the sshd stop Additionally, a description of the more complete service included in the Linux system and instructions for whether to start
