NAME
col - reverse line-feeds filter
SYNOPSIS
col [-bfpx]
DESCRIPTION
The col utility reads from the standard input and writes to the stan‐
dard output. It performs the line overlays implied by reverse line-
feeds, and by forward and reverse half-line-feeds. Unless -x is used,
all blank characters in the input will be converted to tab characters
wherever possible. col is particularly useful for filtering multi-col‐
umn output made with the .rt command of nroff(1) and output resulting
from use of the tbl(1) preprocessor.
The ASCII control characters SO and SI are assumed by col to start and
end text in an alternative character set. The character set to which
each input character belongs is remembered, and on output SI and SO
characters are generated as appropriate to ensure that each character
is written in the correct character set.
On input, the only control characters accepted are space, backspace,
tab, carriage-return and newline characters, SI, SO, VT, reverse
line-feed, forward half-line-feed and reverse half-line-feed. The VT
character is an alternative form of full reverse line-feed, included
for compatibility with some earlier programs of this type. The only
other characters to be copied to the output are those that are print‐
able.
The ASCII codes for the control functions and line-motion sequences
mentioned above are as given in the table below. ESC stands for the
ASCII escape character, with the octal code 033; ESC− means a sequence
of two characters, ESC followed by the character x.

OPTIONS
-b Assume that the output device in use is not capable of backspac‐
ing. In this case, if two or more characters are to appear in the
same place, only the last one read will be output.
-f Although col accepts half-line motions in its input, it normally
does not emit them on output. Instead, text that would appear
between lines is moved to the next lower full-line boundary. This
treatment can be suppressed by the -f (fine) option; in this
case, the output from col may contain forward half-line-feeds
(ESC-9), but will still never contain either kind of reverse line
motion.
-p Normally, col will ignore any escape sequences unknown to it that
are found in its input; the -p option may be used to cause col to
output these sequences as regular characters, subject to over‐
printing from reverse line motions. The use of this option is
highly discouraged unless the user is fully aware of the textual
position of the escape sequences.
-x Prevent col from converting blank characters to tab characters on
output wherever possible. Tab stops are considered to be at each
column position n such that n modulo 8 equals 1.
ENVIRONMENT VARIABLES

that affect the execution of col: LC_CTYPE, LC_MESSAGES, and NLSPATH.

NOTES
The input format accepted by col matches the output produced by nroff
with either the -T37 or -Tlp options. Use -T37 (and the -f option of
col) if the ultimate disposition of the output of col will be a device
that can interpret half-line motions, and -Tlp otherwise.
col cannot back up more than 128 lines or handle more than 800 charac‐
ters per line.
Local vertical motions that would result in backing up over the first
line of the document are ignored. As a result, the first line must not
have any superscripts.
