How to use Beyond Compare in the Terminal

At the command line, the usual way to run Beyond Compare is

in Windows: bcomp.exe @nameofmyscript.bc somefile.txt otherfile.txt

in Linux or Mac: bcomp @nameofmyscript.bc somefile.txt otherfile.txt

Here is a five line script, followed by the syntax for running it in Linux.
