PROGRAM:

NAME


colcrt — filter nroff output for CRT previewing

SYNOPSIS


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

DESCRIPTION


The colcrt utility provides virtual half-line and reverse line feed sequences for terminals
without such capability, and on which overstriking is destructive. Half-line characters and
underlining (changed to dashing `-') are placed on new lines in between the normal output
lines.

The following options are available:

- Suppress all underlining. This option is especially useful for previewing allboxed
tables from tbl(1).

-2 Cause all half-lines to be printed, effectively double spacing the output.
Normally, a minimal space output format is used which will suppress empty lines.
The program never suppresses two consecutive empty lines, however. The -2 option is
useful for sending output to the line printer when the output contains superscripts
and subscripts which would otherwise be invisible.

ENVIRONMENT


The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colcrt as
described in environ(7).

EXIT STATUS


The colcrt utility exits 0 on success, and >0 if an error occurs.

EXAMPLES


A typical use of colcrt would be

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