colcrt(1)
NAME
  colcrt - Filters text processor output for screen previewing

SYNOPSIS
  colcrt [- -2] [file...]

  The colcrt command filters output from text processors such as nroff so
  that it can be previewed on a cathode ray tube (CRT).

OPTIONS
  -   Suppresses underlining; this is useful for previewing boxed tables from
      tbl.

  -2  Causes all half-lines to be printed, effectively doublespacing the
      output.  This is useful when printing output with subscripts and
      superscripts on a line printer, where half-lines do not normally
      appear.

DESCRIPTION
  The colcrt command provides virtual half-linefeed and reverse linefeed
  sequences for terminals without such capability, and on which overstriking
  is destructive. The colcrt command changes underline characters to dashes
  and places them and half-line characters on new lines in between the normal
  output lines.

NOTES
   1.  colcrt cannot back up more than 102 lines.

   2.  General overstriking is lost; as a special case a | (vertical bar)
       overstruck with a - (dash) or _ (underline) becomes a + (plus sign).

   3.  Lines are trimmed to 132 bytes.

EXAMPLES
  The following command line illustrates a typical use of colcrt:

       tbl exum2.n | nroff -ms | colcrt - | more
