Annoying file called "%1" automatically generated when navigating directories

[nunonun2]

Hello

I'm using KUbuntu 22.04 LTS and I've noticed that there is an empty file called "%1" which is randomly generated in many folders. I have noticed that it is created whenever I open Dolphin and press F4 to open a terminal, but I think it is also created under other circumstances that I haven't identified yet.

How can I prevent these files from being created?

I found the problem. It was a typo in my .zshrc, in the `agent_run_state` variable (a "%" instead of an "&").
In case it helps somebody, the code should be:

agent_run_state=$(ssh-add -l >| /dev/null 2>&1; echo $?)
