programmatic reboot / shutdown

[LazyLarry]

I have a program originally written for ubuntu that is now running on TC. There is both a shutdown and a reboot button as part of the program. These dont seem to do anything in TC. They simply call
reboot(0x01234567) and reboot(0xcdef0123).
What do i need to do go be able to support these buttons?

Thanks in advance.

Are shutdown/reboot executed as root?

If it is not an option to prepend sudo to the commands you use, then create reboot and shutdown scripts in ~/.local/bin/ that will add the needed sudo, eg. for reboot:

Code: [Select]

#!/bin/sh
exec sudo reboot

Tested, those system calls work fine on TC when run as root.

OK, thanks for the feedback. I don't seem to be able to run the program from the command line. I can run it from the fluff browser, but when I go to the directory and type the filename I get a "not found" error. I have just copied this program into RAM from an external drive. Do I need to do something to TC to tell it there's a new program?
ALso, to run it as root, do I just stick sudo in front of the filename or do i need to do more.

Thanks,

What do you mean "copied this program into RAM"?
Unless the program is in one of the directories in $PATH, you will need to provide a proper full or relative path to the executable.
Is it executable?

You can run 'hash -r' to refresh your program hash.

By copying into RAM i mean I have the executable on an external drive. I copy it into the /opt directory, which I assume is in RAM.

i actually can run it now, by specifying the full path. thanks for that tip. I thought If i was in the directory ( cd /opt) i could run it from the filename. I hadnt thought of using the full path.

However, I'm back to my original problem. I type "sudo /opt/filename" and the program runs, but my shutdown button only closes the app but doesn't do shutdown.

If it's any help, in the terminal window, when the program exits i get a message
init: must be run as PID 1

/opt  is not in PATH

try
echo $PATH

Perhaps best to read the wiki on making Extensions, then create an extension which installs your app into /usr/local/bin
 

You might want to create a menu item also.  For this follow working desktop entry examples in /tmp/tcloop

good luck


though I'm not sure why you would reinvent the wheel when these features already exist

Hi LazyLarry

... but when I go to the directory and type the filename I get a "not found" error.

If you are in the directory, you can execute the filename like this:

Code: [Select]

./FILENAME

... when the program exits i get a message init: must be run as PID 1

That sounds like you are not running as root. Did you try running it with  sudo ?

[LazyLarry]

yes, i tried it as sudo, but no joy either
