grep: Other Options

 
 2.1.7 Other Options
 -------------------
 
 ‘--line-buffered’
      Use line buffering on output.  This can cause a performance
      penalty.
 
 ‘-U’
 ‘--binary’
      On platforms that distinguish between text and binary I/O, use the
      latter when reading and writing files other than the user’s
      terminal, so that all input bytes are read and written as-is.  This
      overrides the default behavior where ‘grep’ follows the operating
      system’s advice whether to use text or binary I/O.  On MS-Windows
      when ‘grep’ uses text I/O it reads a carriage return–newline pair
      as a newline and a Control-Z as end-of-file, and it writes a
      newline as a carriage return–newline pair.
 
      When using text I/O ‘--byte-offset’ (‘-b’) counts and
      ‘--binary-files’ heuristics apply to input data after text-I/O
      processing.  Also, the ‘--binary-files’ heuristics need not agree
      with the ‘--binary’ option; that is, they may treat the data as
      text even if ‘--binary’ is given, or vice versa.  File and
      Directory Selection.
 
      This option has no effect on GNU and other POSIX-compatible
      platforms, which do not distinguish text from binary I/O.
 
 ‘-z’
 ‘--null-data’
      Treat input and output data as sequences of lines, each terminated
      by a zero byte (the ASCII NUL character) instead of a newline.
      Like the ‘-Z’ or ‘--null’ option, this option can be used with
      commands like ‘sort -z’ to process arbitrary file names.
