i know but i've been able to run somewhat similar batch files on my mac os x but this one isnt working strangely, it must be a different version or something because for the other batch files in the code i typed "-Xmx500m" in part of it but in text edit opening this one up i saw it says "-Xmx800m", so i tried replacing 500m with 800m in the code, but it didn't work. and following the xmx500m was "EGUI" but when i typed in the whole code into the terminal, it said "EGUI" command could not be found. For other batch files with variations i could just switch the information into the code for example for "/Versions/1.6.0/" if in text edit it said something other than versions 1.6.0, i would replace it with that and it would work. thanks for the post, every post is appreciated.
