NAME
     unexpand - change spaces to tabs

SYNOPSIS
     unexpand [ -a ] [ filename ... ]

DESCRIPTION
     Unexpand puts tabs back into the data from the standard
     input or the named files and writes the result on the
     standard output.  By default, only leading blanks and tabs
     are reconverted to maximal strings of tabs.

OPTIONS

        resultant file by replacing two or more characters.

EXAMPLES
     The following example copies the data in the file text to
     the file text.t, replacing spaces with tabs wherever they
     would save space:

          unexpand -a text > text.t

RETURN VALUE
     [NO_ERRS]      Command completed without error.

     [USAGE]        Incorrect command line syntax. Execution
                    terminated.

     [P_ERR]        A system error occurred. Execution
