Problem with FreeRapid in Linux

I'm using FreeRapid a file hosting Java downloading program in Linux. In Windows it allows me to auto shutdown when all downloads are done, but in Linux, I get the following error:

System command "shutdown" is not supported or defined on this system. Check your settigs in the file "syscmd.properties".

My "syscmd.properties" file displays the following:

"# ******************************

# ******** BASIC INFO **********

# ******************************



# This configuration file provides system commands/scripts for Java application

# on Linux or MacOS operating system. MS Windows users don't need to use this file (it's ignored) at all.

# If you make some good configuration for your system and if you want to share it, please don't hesitate to send this file to info@wordrider.net.

# This file cannot have universal settings, because every UNIX implemenetation has own implementation of these commands.

#

# The commands are called from the application (eg. shutdown system, when all downloads are complete).

# This configuration file has a syntax of Java properties file (key=value, # - line comment. \n - new line, \t - tabulator).

#

# Application searches for this file in its configuration directory as first (~/.APPCODE),

# then it searches for this file in application's home directory.

# It's recommended to copy this file to its configuration directory (~/.APPCODE) for easier upgrading to newer version of the application.

# %DIR% - current application directory (absolut path) - like /home/userid/appname

#### Shortcuts commands

# Meaning of these commands is obvious

# Application WAITS for a result code.







#create_desktop_shortcut=



#create_startmenu_shortcut=



#create_startup_shortcut=



#create_quicklaunch_shortcut=



#### Application restart command

restart_application=java -jar %DIR%/frd.jar %ARGS%





#### System shutdown commands

# It's highly recommended to insert sleep pause (eg. 2 seconds) before executing this type of command.

# Application DOESN'T WAIT for a result code.





#

system shutdown - poweroff - 'sudo poweroff'





shutdown=



#

# system reboot - 'sudo reboot'

#



#reboot=



#

# system hibernate - suspend to disk

#



#hibernate=



#

# system standby - suspend to RAM

#



#standby=

Anyone know what setting I need to change to make this shutdown feature work in Linux? Thanks.

Did you read the basic info section?

No, where is it?

On your syscmd.properties file.

Ah, yeah, I read it but I don't understand script commands. That's why I asked if anyone could tell me what to do.

Scroll down, you can find the command. I can see that removed comments there too.
