Look under /home/tc, /home/tc/.config or /usr/local/etc - if it's a gtk3 app, you could look with dconf-editor.

You could also take a look at the app's documentation.

You can also install strace to trace the syscall open.
To see what files the program/app tries to open.

Code: (bash) [Select]

strace -e trace=open your-command-here

Hi patrikg
That looks like a pretty handy command, so I decided to try it out. I entered:

Code: [Select]

strace -e trace=open editor Notes.txt
To my surprise, I got nothing. So I tried this:

Code: [Select]

strace -e trace=open editor Notes.txt | grep -i open
It turns out there's an  openat  syscall  that was being used instead. Changing it to this works:

Code: [Select]

strace -e trace=open,openat editor Notes.txt
As of kernel version 5.6, there is now also an  openat2  syscall.

Hi Rich.
Thank you, didn't know that.
Haven't used that command for a while.
But everyday you learn something.   :) :)

Hi patrikg
Yup, you taught me something and I taught you something. That's a win win in my book. ;D
