I am trying to create a new schedule for WittyPi (On/off scheduling of RaspberryPi). In the manual it seemed really easy (http://www.uugear.com/doc/WittyPi3_UserManual.pdf) but I fear I messed up something. I cannot change the example scripts (as stated in the manual), because when I want to save my changes I get "Error saving file. Error opening file "[/../../]": Permission denied The file on disk may now be truncated!" I also tried to create a new file and save it to the "schedules" location. I get "Error opening file "[/.../.../...]": Permission denied the file on disk may now be truncated!"

However, I can save my Schedule file perfectly fine in eg the "Downloads" folder. So I guess there is something wrong with the permissions. Is there any way to fix it? I have no experience or knowledge of Raspberry Pi so it could be just basics (and I did not understand the answers I found in the "Search" at all..). I really want to work with the WittyPi but I am stuck totally at the start...

Thank you for helping me out!

Katharina

PS: I use a RaspberryPi 3B+ and Witty Pi 3.

    What command are you using to edit the scripts? Simple fix may be to run the command to edit the files with sudo (so if you use nano, then you would run sudo nano) at the beginning but that may have other effects... Dec 18, 2020 at 18:25
  • Oh. Excuse me for not having found out that by myself... The sudo command did the job perfectly fine. Thank you for your quick answer!

The command "sudo" nano fixes the problem. Like this one goes around the "Permission denied" issue. Thanks @Unsigned_Arduino for the solution!
