NAME
col – column alignment
SYNOPSIS
col
[
-bfx
]
DESCRIPTION
Col
overlays lines to expunge reverse line feeds
(ESC-7)
and half line feeds (ESC-9 and ESC-8)
as produced by
nroff
for .2C in
ms(6)
or
man(6)
and for
tbl(1).
Col
is a pure filter.
It normally emits only full line feeds;
option
-f
(fine) allows half line feeds too.
Option
-b
removes backspaces, printing just one of each pile of overstruck
characters.
Col
normally converts white space to tabs;
option
-x
overrides this feature.
Other escaped characters and non-printing characters are ignored.
EXAMPLES
tbl file | nroff -ms | col | p
Format some tables for printing on typewriters;
use
col
to remove reverse line feeds, and
paginate the output.

BUGS
Col
can’t back up more than 128 lines or
handle more than 800 characters per line,
and understands
VT
(013) as reverse line feed.
