File - determine file type
File tests each argument in an attempt to classify it. There are three sets of tests, performed in this order: filesystem tests, magic number tests, and language tests. The first test that succeeds causes the file type to be printed. For information on Mach-O binaries, it is suggested that one uses the command `otool -fv`.
To install file, paste this in macOS terminal after installing MacPorts
sudo port install file
