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 doublespac-
       ing 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 characters 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
