colcrt
colcrt(1) General Commands Manual colcrt(1)Name
colcrt - filter nroff output for CRT previewing
Syntax
colcrt [-] [-2] [file...]
Description
The command 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.
Options
- Suppresses all underlining. It is especially useful for previewing allboxed tables from
-2 Causes half-lines to be printed, 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 would be:
tbl exum2.n | nroff -ms | colcrt - | more
Restrictions
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.
