capture STDOUT from shell script

jeremyvancleve · September 20, 2019

I have a shell script that I use to process specific fields (title, journal name, etc) and I can execute it with nsIProcess, but I can't capture the stdout from the script.

Is there some way to do this in Zotero?

(You can use Zotero.Utilities.Internal.exec(cmd, args) instead of using nsIProcess directly.)

There's no way that I know of to get the output in XPCOM, but you can just adjust the script to log to a file, or call one script from another script and redirect that way.

Just in case you're venturing there: I tried capturing output using Subprocess (https://searchfox.org/mozilla-central/source/toolkit/modules/subprocess/Subprocess.jsm) but gave up because I would get frequent random (non-catchable) crashes.

Thanks for the input dstillman and emilianoeheyns!

Yes, I was looking at subprocess so its good to know to stay away from it.

You're free to try of course, but I had no end of troubles with it.
