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.   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 over‐
       striking is destructive. The colcrt command changes  underline  charac‐
       ters to dashes and places them and half-line characters on new lines in
       between the normal output lines.

NOTES
       colcrt cannot back up more than 102  lines.   General  overstriking  is
       lost;  as  a special case a | (vertical bar) overstruck with a - (dash)
       or _ (underline) becomes a + (plus sign).  Lines	 are  trimmed  to  132
       bytes.

EXAMPLES
       The  following  command	line  illustrates a typical use of colcrt: tbl
       exum2.n | nroff -ms | colcrt - | more
