COLCRT(1) User Commands COLCRT(1) NAME
colcrt - filter nroff output for CRT previewing SYNOPSIS
colcrt [options] [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. 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 invisible. -V, --version Output version information and exit. -h, --help Output help and exit. 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. AVAILABILITY
The colcrt command is part of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils/util- linux/>. util-linux September 2011 COLCRT(1)
