colcrt1

Usage

Overview

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.

Options

-, --no-underlining

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

-2, --half-lines

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 partially invisible.

-h, --help

Display help text and exit.

-V, --version

Display version and exit.
