Running on MacOS (solution)

[dsiher]

I was trying to run concat and ran into the same problems as #36 and #16 but found out the fix.

When downloading the file, if using Safari, the extension will sometimes be switched from no extension to a .dms file, so you have to remove the extension.

Once you get the file without an extension, you have to run chmod +x ./concat_mac in terminal to associate the file as a unix executable or else terminal won't allow you to run it.

After that you should be able to run the file using ./concat_mac from terminal and continue to use the functionality as stated in the README.

Thanks. I have updated the readme with your fix.
