 3.2 `tac': Concatenate and write files in reverse
 =================================================
 
 `tac' copies each FILE (`-' means standard input), or standard input if
 none are given, to standard output, reversing the records (lines by
 default) in each separately.  Synopsis:
 
      tac [OPTION]... [FILE]...
 
    "Records" are separated by instances of a string (newline by
 default).  By default, this separator string is attached to the end of
 the record that it follows in the file.
 
    The program accepts the following options.  Also see  Common
 options.
 
 `-b'
 `--before'
      The separator is attached to the beginning of the record that it
      precedes in the file.
 
 `-r'
 `--regex'
      Treat the separator string as a regular expression.  Users of `tac'
      on MS-DOS/MS-Windows should note that, since `tac' reads files in
      binary mode, each line of a text file might end with a CR/LF pair
      instead of the Unix-style LF.
 
 `-s SEPARATOR'
 `--separator=SEPARATOR'
      Use SEPARATOR as the record separator, instead of newline.
 
 
    An exit status of zero indicates success, and a nonzero value
 indicates failure.
