Hibernate at certain hours. It's possible?

Uff, too complicated for me hehehe.

I'm going to leave it as in the image that works for me ("cron") and I don't get complicated trying to do a bash.

I will delete the sudo as you have indicated.

Thank you so much.

EDIT:

I have a problem.
I have an external hard drive connected, but when the computer wakes up, the drive is not mounted, and I have to manually click mount. Is there any way so that after waking up with the cron command, the hard drive is mounted?

Maybe with this command in cron?

mount /dev/sdb1​

Thank you.

Best to combine it with a logical AND, so the entry in the systemwide crontab would be something like

30 16 * * *    root    rtcwake -m mem -l -t "$(date -d 'today 22:30:00' '+\%s')" && mount -MOUNTOPTIONS /DEVICE /MOUNTPOINT

Replace -MOUNTOPTIONS, /DEVICE and /MOUNTPOINT with the correct values.

See man mount.

At this point I would really consider using a shell script or at least to pipe the (error) output into a log file…

Hello, thanks for helping.

I'm sorry if I don't understand many of the things you explained to me, but I really don't know much. I try to look for information on the things you tell me, but either I can't find them, or I don't know what I'm looking for or I don't understand what I'm reading hehehe.


I really don't know what this is: -MOUNTOPTIONS /DEVICE /MOUNTPOINT

I think, /device is /dev/sdb1, and not sure if Mountpoint is /media/pollo/Pollo but -MOUNTPINTS really i have no idea hehe.


I have gotten this information from the disk (photo), but I don't know which one it is.

At this point I would really consider using a shell script or at least to pipe the (error) output into a log file…

I think this is way beyond me, any guide?


Thanks and regards.

You could look here https://www.kubuntuforums.net/forum/.../documentation or search the internet for all your fundamental Linux questions.
And here is a YouTube channel that has a series about Linux CLI commands and many other things: https://www.youtube.com/@LearnLinuxTV

To get a list of block devices in *Ubuntu enter e.g. lsblk -e7 or lsblk -f -e7 in the Konsole terminal emulator.
To get a list of USB devices enter e.g. lsusb or lsusb -tv in Konsole.

And there are the man pages for each command (e.g. enter man mount in Konsole as I suggested above).
