Take a screenshot every 20 seconds or so

[tom66]

I would like to take a screenshot every 20 seconds or so and save it to a folder behind the scenes. Is this possible, if so, how?

Thanks,
Tom

You could write a shell script:

#!/bin/bash

while true; do
    scrot ~/screenshots/%M-%S.png
    sleep 20
done

exit 0

It beeps every time. Can I stop it from doing that?

Thanks,
Tom

Are you spying on someone? lol... is it a system beep or speakers beeping?

It's a system beep. I know, because it does it on mine. But I dunno how to disable the pcspkr.

No, it's an experiment of mine. I like to film myself coding then put it into a timelapse.

Anyways I decided to compile from source and comment out 'XBell' in main.c. Great. 'cept I can't seem to compile it. Could someone point instructions. I've configured fine, then make, then sudo make install, are there more steps or something?

I ran the script, and it does not make a beep for me.

Okays, I found that temporarily disabling the pcspkr module works for me:

rmmod pcspkr

Thanks for everyone's help. It now works fine.

To remove the system speaker module, type in the terminal:

sudo modprobe -r pcspkr

Run the script again, and with a bit of blind faith. It should be quiet now

To make this change permanent, edit your blacklist file.

sudo gedit /etc/modprobe.d/blacklist

and add the line

blacklist pcspkr

at the bottom.
