ARGF.read([length [, outbuf]]) â string, outbuf, or nil
Instance Public methods
Reads _length_ bytes from ARGF. The files named on the command line
are concatenated and treated as a single file by this method, so when
called without arguments the contents of this pseudo file are returned in
their entirety.
_length_ must be a non-negative integer or nil. If it is a positive
integer, +read+ tries to read at most _length_ bytes. It returns nil
if an EOF was encountered before any
