NAME
      into - copy into a file without destroying it

 SYNOPSIS
      into [ -f ] outfile

 DESCRIPTION
      Into copies its standard input into the
      specified outfile, but doesn't actually
      modify the file until it gets EOF.  This is
      useful in a pipeline for putting stuff back
      in the "same place." The outfile is not
      overwritten if that would make it zero
      length, unless the -f option is given.  That
      option also forces overwriting of the outfile
      even if it is not directly writable (as long
      as the directory is writable).

 SEE ALSO
      pipe(2)

 BUGS
      For efficiency reasons, the directory
      containing the outfile must be writable by
      the invoker.
      The original outfile's owner is not
      preserved.
