getswill useKernel#gets, which first tries to read the contents of files passed in throughARGV. If there are no files inARGV, it will use standard input instead (at which point it’s the same asSTDIN.gets.Note: As echristopherson pointed out,
Kernel#getswill actually fall back to$stdin, notSTDIN. However, unless you assign$stdinto a different input stream, it will be identical toSTDINby default.http://www.ruby-doc.org/core-1.9.3/Kernel.html#method-i-gets
