NAME
colcrt
- filter nroff output for CRT previewing
SYNOPSIS
[-
]
[-2
]
[file ...
]
DESCRIPTION
The
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.
EXAMPLES
A typical use of
would be
tbl exum2.n | nroff -ms | colcrt - | more
SEE ALSO
col(1),
more(1),
nroff(1),
troff(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.
