     SYNOPSIS

     DESCRIPTION
          This documentation is no longer being maintained and may be
          inaccurate or incomplete.  The Texinfo documentation is now
          the authoritative source.

          This manual page documents the GNU version of expand.
          expand writes the contents of each given file, or the
          standard input if none are given or when a file named `-' is
          given, to the standard output, with tab characters converted
          to the appropriate number of spaces.  By default, expand
          converts all tabs to spaces.  It preserves backspace
          characters in the output; they decrement the column count
          for tab calculations.  The default action is equivalent to
          -8 (set tabs every 8 columns).

        OPTIONS
          -, -t, --tabs tab1[,tab2[,...]]
               If only one tab stop is given, set the tabs tab1 spaces
               apart instead of the default 8.  Otherwise, set the
               tabs at columns tab1, tab2, etc. (numbered from 0) and
               replace any tabs beyond the tabstops given with single
               spaces.  If the tabstops are specified with the -t or
               --tabs option, they can be separated by blanks as well
               as by commas.

          -i, --initial
               Only convert initial tabs (those that precede all non
               space or tab characters) on each line to spaces.

          --help
               Print a usage message and exit with a status code
               indicating success.

          --version
               Print version information on standard output then exit.
