+== NAME
+
+col - filter reverse line feeds from input
+
+== SYNOPSIS
+
+*col* _options_
+
+== DESCRIPTION
+
+*col* filters out reverse (and half-reverse) line feeds so the output is in the correct order, with only forward and half-forward line feeds. It also replaces any whitespace characters with tabs where possible. This can be useful in processing the output of *nroff*(1) and *tbl*(1).
+
+*col* reads from standard input and writes to standard output.
+
+== OPTIONS
+
+*-b*, *--no-backspaces*::
+Do not output any backspaces, printing only the last character written to each column position.
+
+*-f*, *--fine*::
+Permit half-forward line feeds. Normally characters destined for a half-line boundary are printed on the following line.
+
+*-h*, *--tabs*::
+Output tabs instead of multiple spaces.
+
+*-l*, *--lines* _number_::
+Buffer at least _number_ lines in memory. By default, 128 lines are buffered.
+
+*-p*, *--pass*::
+Force unknown control sequences to be passed through unchanged. Normally *col* will filter out any control sequences other than those recognized and interpreted by itself, which are listed below.
+
+*-x*, *--spaces*::
+Output multiple spaces instead of tabs.
+
+*-H*, *--help*::
+Display help text and exit.
+
+*-V*, *--version*::
+Print version and exit.
+
+== CONFORMING TO
+
+The *col* utility conforms to the Single UNIX Specification, Version 2. The *-l* option is an extension to the standard.
+
+== NOTES
+
+The control sequences for carriage motion that *col* understands and their decimal values are listed in the following table:
+
+*ESC-7*::
+reverse line feed (escape then 7)
+*ESC-8*::
+half reverse line feed (escape then 8)
+*ESC-9*::
+half forward line feed (escape then 9)
+*backspace*::
+moves back one column (8); ignored in the first column
+*newline*::
+forward line feed (10); also does carriage return
+*carriage return*::
+(13)
+*shift in*::
+shift to normal character set (15)
+*shift out*::
+shift to alternate character set (14)
+*space*::
+moves forward one column (32)
+*tab*::
+moves forward to next tab stop (9)
+*vertical tab*::
+reverse line feed (11)
+
+All unrecognized control characters and escape sequences are discarded.
+
+*col* keeps track of the character set as characters are read and makes sure the character set is correct when they are output.
+
+If the input attempts to back up to the last flushed line, *col* will display a warning message.
+
+== HISTORY
+
+A *col* command appeared in Version 6 AT&T UNIX.
