I have a problem with okular (or it is actually not a problem but irritating).
Because of reasons I sometimes start okular from command line (zsh) and after I closed okular (sometimes after some seconds, not immediately which irritates me) it print something like:

schoenix:~$ okular file.pdf 
schoenix:~$ Creating the cache for: "/home/schoenix/file.pdf"

After that it stops and I have to kill it via Ctrl+C, and sometimes it came some seconds later and I already typed a new command and it mixed with this output.

I want either disable the cache (how?) or disable this output.

I don't see this with okular on my system (up-to-date Arch Linux, Okular 17.12.1-1). There is no output at all for me. Nevertheless, here are two options.

1. Just close the terminal and open another one.


2. Suppress all output with okular file.pdf >/dev/null
   

If the last is too annoying to type constantly, you could always make an alias. Put the following in ~/.zshrc:

alias okular='okular >/dev/null'
