COLCRT(1) User Commands COLCRT(1)
colcrt - filter nroff output for CRT previewing
colcrt [options] [file...]
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.
-, --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
Display version information and exit.
-h, --help
Display help text and exit.
A typical use of colcrt would be:
tbl exum2.n | nroff -ms | colcrt - | more
col(1), more(1), nroff(1), troff(1), ul(1)
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.
The colcrt command appeared in 3.0BSD.
