COLCRT(1) BSD General Commands Manual COLCRT(1)NAME
colcrt -- filter nroff output for CRT previewing
SYNOPSIS
colcrt [-] [-2] [file ...]
DESCRIPTION
Colcrt 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.
Available options:
- Suppress all underlining. This option is especially useful for previewing allboxed tables from tbl(1).
-2 Causes 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.
EXAMPLES
A typical use of colcrt would be
tbl exum2.n | nroff -ms | colcrt - | more
SEE ALSO nroff(1), troff(1), col(1), more(1), ul(1)BUGS
Should fold underlines onto blanks even with the '-' option so that a true underline character would show.
Can't back up more than 102 lines.
General overstriking is lost; as a special case '|' overstruck with '-' or underline becomes '+'.
Lines are trimmed to 132 characters.
Some provision should be made for processing superscripts and subscripts in documents which are already double-spaced.
HISTORY
The colcrt command appeared in 3.0BSD.
