Init/Shutdown Scripts
2 minute read
TrueNAS provides the ability to schedule commands or scripts to run at system startup or shutdown.
Go to Tasks > Init/Shutdown Scripts and click ADD.
Init/Shutdown Options
| Setting | Value | Description |
|---|---|---|
| Description | string | Write any comments about this task. |
| Type | drop-down menu | Select Command for an executable or Script for an executable script. |
| Command or Script | string | When Command is selected, enter the command with any options. When Script is selected, click (Browse) to select the script from an existing pool. |
| When | drop-down menu | Select when the Command or Script runs: Pre Init: early in the boot process, after mounting filesystems and starting networking. Post Init: at the end of the boot process, before TrueNAS services start. Shutdown: during the system power off process. |
| Enabled | checkbox | Enable this task. Unset to disable the task without deleting it. |
| Timeout | integer | Automatically stop the script or command after the specified number of seconds. |
Scheduled commands must be in the default path. The full path to the command can also be included in the entry. The path can be tested with which {commandname} in the Shell. When available, the path to the command is shown:
[root@freenas ~]# which ls
/bin/ls
When scheduling a script, test the script first to verify it is executable and achieves the desired results.
Init/shutdown scripts are run with sh.
All saved Init/Shutdown tasks are shown in Tasks > Init/Shutdown Scripts.
Click (Options) for a task to Edit or Delete that task.
