Proper way to exec GUI applications in script mode

[mardukbp]

I want to use rofi to quickly open a PDF file. I am using the following script:

if [ -z "$@" ]
then
    cd ~/Zotero/ && ls 
else
    zathura ~/Zotero/$@
fi

When I select the file, it is opened and I get the rofi prompt again but the keyboard is dead. I can only switch to another tty and kill rofi. I tried sending stdout and stderr to /dev/null and also tried using different PDF viewers. I suspect that I am doing something wrong.

zathura keeps running, so rofi has no way of knowing if there is going to be more data coming or not. (e.g. script hasn't finished.)

Something like this works:

    if [ -z "$@" ]
    then
        cd ~/Downloads/ && ls *.pdf
    else
        zathura "~/Downloads/$@" > /dev/null 2>&1 &
    fi
