Class Method Details

.binary?(file) ⇒ Boolean

Method taken from: github.com/djberg96/ptools –

Returns whether or not file is a binary file. Note that this is not guaranteed to be 100% accurate. It performs a “best guess” based on a simple test of the first File.blksize characters.

Example:

File.binary?(‘somefile.exe’) # => true File.binary?(‘somefile.txt’) # => false – Based on code originally provided by Ryan Davis (which, in turn, is based on Perl’s -B switch).

Returns:

  • (Boolean)
