Title: Set Shutdown Time
Post by: Boss 429 on April 28, 2017, 10:32:15 AM

Hi,

I've been searching the forums and I'm not really seeing a way to shut down TC at a specific time. I would like to be able to shut the machines down at night without having to interact with them. The closest thing I've found was setting up a delay timer, but that won't quite work for my application.

Thank you

hi,

you are looking for a tool like cron.
with cron-jobs you can define timetables for commands f.e. shutdown at a specific time.

keep on hacking :-)

You can use the  cron  bot code to start cron at boot.
The command  crontab -e  is used to create a cron job. An editor will open where you can write in something like this:

Code: [Select]

00 00 * * * /usr/bin/filetool.sh -b ; /usr/bin/sudo /sbin/poweroff
This would, at midnight, perform a backup and shutdown the system.

Then add  var/spool/cron/crontabs  to your backup.

Misalf, When I tried to insert the code into crontab, it wouldn't allow me to run a backup, and the next line of text started to jump across the screen every time I hit the return key to go to the next line. I'm not really sure what would be causing that, but it's consistently doing it

Do not use leading "/" in .filetool.lst.

Works here.
Are you familiar with the  vi  editor? It can be quite confusing to use. Maybe that's what happened?

I'm fairly familiar with vi editor. I'm just not sure if I'm saving it with the wrong extension? maybe the wrong location? I have entered the code as you have it in your previous post. I get a notification on boot that Crond is running as well.

With  crontab -e , an editor opens with a temporary file name which must not be changed nor must the location be specified; cron takes care about that.

In lots of Linux dists. You can set the EDITOR environment variable.
So

Code: (bash) [Select]

crontab -e
can use that, instead of the default vi.

Code: (bash) [Select]

export EDITOR=nano

I'm sorry for the poor quality, my camera wouldn't focus and I'm not sure how to take screenshots in TC.. but every time I run crontab -e, this is what happens when I close the command. I'm not sure why it's doing this. I even tried a fresh install of TC just to make sure that it wasn't something that I might have caused.

Hi Boss 429
It appears to be executing a  find  command upon returning to the command prompt for some reason. Also the carriage
returns are behaving like just linefeeds.

I ran the find command to show what it was doing, and when I try to run the backup command, it won't let me. it will more or less "lock up" and not let me do anything unless I reboot

Hi Boss 429
I see, so if you were to just hit enter a bunch of times the prompt would keep shifting down 1 line and to the right by
the width of the prompt. I've seen that behavior when a program launched from a terminal crashes or misbehaves. I
close the terminal and open a new one in that case.

That's exactly what it's doing. Would I just need to run the "exit" command and log back to in to piCore to do so? I'm not using a GUI interface

Hi Boss 429
That's certainly worth giving a try.

The issue in the image is normally called the "staircase effect" it can be fixed with

Code: [Select]

stty onlcr but it's easier to remember

Code: [Select]

stty sane
I would guess you actual problem is the broken (for the command line) ondemand script in the current version.
