Custom Command for PDF-Viewer on Linux

tim.hilt

I would like to open PDFs from Zotero in a qpdfview-session. For this to actually work i would have to launch the following command:

qpdfview --unique --instance INSTANCENAME FILENAME.pdf

Unfortunately when choosing the PDF-viewer through the settings-dialog i can only choose executables and not edit the specific command. I tried to manually edit prefs.js and replaced the field extensions.zotero.fileHandler.pdf (which previously was "/usr/bin/qpdfview") with "/usr/bin/qpdfview --unique --instace a". Now when i restart Zotero and take a look at the settings, the command for the PDF-viewer is displayed as i entered it in prefs.js, however when i now double-click on a PDF to open it it's opened in the browser.

When i start Zotero from the terminal and look at the output when opening a PDF i just see:

Opening in existing browser session.
[0921/115538.745057:ERROR:nacl_helper_linux.cc(308)] NaCl helper process running without a sandbox!
Most likely you need to configure your SUID sandbox correctly

Which is more likely to be a Google-Chrome related output.

Can i achieve my goal somehow? How could i do that?

First reset that pref. It's meant to be an executable.

I haven't tested, but you can probably use a shell script for this.

Yes, that was it. Fabulous! My script looks as follows:

#!/usr/bin/env bash
/usr/bin/qpdfview --unique --instance zotero "$1"

Thanks!
