Thanks scrptrx, it looks like those script files are extremely simple and just streamline some variables, but it's still executing: XNB-Nodes unpack/pack <from folder> <to folder> ...and that's what is failing. The error may be due to LZX compression as stated here: http://community.playstarbound.com/threads/solved-linux-beta-xnb-extracting.120317/#post-3029050 It seems the file format simply isn't standardized and stable enough so that stable tools can be created to read/write to that format, especially without the .NETFrameworkWindowsMicrosoft software stack. I know Mono exists as an attempt to implement .NET on Linux, and I think Microsoft even officially supports it now, but even if that were enough to make it work, you'd still need the Linux version of XNB-Nodes in order to utilize it. Given how popular Microsoft software is on Linux, I'm not too surprised there isn't something in place yet. Although now with Visual Studio, Moonlight, Mono, etc, being on Linux, you'd think there would be something somewhere, but I guess it's still all too new. Oh well, I'll leave Stardew modding to other modders for now then.
