![]() ![]() This behavior also varies significantly on the graphical program (gnome, unity, kdm. 1 systemctl systemctl is the central management utility that controls the systemd system, manages the services and examine the system state. We will outline below the most commonly used tools. You can refer to this related post to read about startup scripts and their execution order.Ī side note: after reading the post mentioned above, you will realize that it is unsure whether a bash startup script is executed, when it is executed (is it run before or after you log in to the graphical screen?). List startup services at boot time There are many options that allow us to see the list of services at boot time. To do so, open a command line terminal and execute the following command: systemctl status apache2 Currently this particular service is disabled to start during the system boot time Note that the vendor preset text tells you whether the service starts automatically by default or not. Method 3 (inconsistent): Create a shell startup script Therefore, I will not discuss other perspectives such as when the cron job gets executed, where it is stored, who the user is running it, or whether this cron job gets executed with a sudoer privilege.Ĭron is not always installed by default in some Linux distributions (such as Arch Linux) and requires a manual installation. Not only is there a bug in some Debian variants, but the behavior of the cron job is also inconsistent between reboots and shutdowns/starts. Nonetheless, this approach is not reliable. Method 2 (unreliable): Add a startup cron jobĪdd a crontab line with the repeat section as i.e., run crontab -e and append the following line to the opened file. Firstly, open terminal either from system app launcher or by pressing Ctrl+Alt+T on keyboard. Refer to this digital ocean post for more detail on the systemd unit file structure. Method 1.) Set RTC to local time zone in Ubuntu: Though it’s not recommended, set the Real Time Clock (RTC) to use local time zone just works. To enable this service when startup, run systemctl enable my-service. You can now start/stop this service with systemctl start my-service / systemctl stop my-service. Hence, the above unit file is equivalent to: # ExecStop=/home/transang/startup.sh stop # ExecReload=/home/transang/startup.sh reload ![]() ĮxecStart=/home/transang/startup.sh start service extension in /etc/systemd/system, for example /etc/systemd/system/rvice, with the following content. Method 1 (most reliable): Create a systemd startup serviceĬreate a systemd unit file with. Suppose that the script to run is at /home/transang/startup.sh. In this post, I will introduce three ways to create a startup script in Ubuntu: systemd ( systemctl command), cron job ( directive), and shell startup script (. ![]()
