Working bash command fails with OSSubprocess depending on input file

Hi everyone,

 

I’m currently having problems with executing bash commands through OSSubprocess (version: #stable, as of today) on OS X 10.11.6. I’m using the command line tools of a program called ParseCit to extract metadata from .txt files. It works well for about 75% of all txt files I’ve tested it with, but fails on the remaining 25%. This isn’t due to ParseCit though, since it works on all input files, when I issue the command directly from a bash. I’ve prepared two test txt files – one that works fine (goodExample.txt) and one that doesn’t work (badExample.txt) with OSSubprocess. The conversion for both files works fine when issuing the following respective commands in a shell or bash:

               

                /Users/silas/Documents/TestWithOSS/tools/mac/parsecit/bin/citeExtract.pl -m extract_all /Users/silas/Documents/TestWithOSS/test_txt/badExample.txt

/Users/silas/Documents/TestWithOSS/tools/mac/parsecit/bin/citeExtract.pl -m extract_all /Users/silas/Documents/TestWithOSS/test_txt/goodExample.txt

 

Using OSSubprocess, it works well for goodExample.txt, the result looks like this:

 

Unfortunately, that exact same method/command fails, if the target file is badExample.txt instead.

 

Below, you can find two methods I’ve tried for badExaple.txt, neither of which work. Method 2 (which is the one I used in the above screenshot for goodExample.txt) has a stderr stream, its contents are just above the Method 2 screenshot. It looks like it should be a ParseCit problem, but, as I’ve mentioned above, it works fine when done directly in a bash or shell.

 

In this GitHub repo there are the “tools” folder containing a compiled version of ParseCit, a corresponding INSTALL.md with all the necessary install steps for ParseCit, and a folder “test_txt”, which contains goodExample.txt and badExample.txt. The EES-INSTALL.md in the same repo is not relevant in this context.

 

If anyone has an idea what could be the problem or how I could get it to work, I’d be very happy.

 

Best,

Silas
