+.SH COL
+col - filter reverse line feeds from input
+.SH SYNOPSIS
+.B col
+[options]
+.SH DESCRIPTION
+.B 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, and replaces
+white-space characters with tabs where possible.  This can be useful in
+processing the output of
+.BR nroff (1)
+and
+.BR tbl (1).
+.PP
+.B col
+reads from standard input and writes to standard output.
+.SH OPTIONS
+.TP
+\fB\-b\fR, \fB\-\-no-backspaces\fR
+Do not output any backspaces, printing only the last character written to
+each column position.
+.TP
+\fB\-f\fR, \fB\-\-fine\fR
+Forward half line feeds are permitted
+.I fine
+mode.  Normally characters printed on a half-line boundary are printed on the
+following line.
+.TP
+\fB\-p\fR, \fB\-\-pass\fR
+Force unknown control sequences to be passed through unchanged.  Normally,
+.B col
+will filter out any control sequences from the input other than those
+recognized and interpreted by itself, which are listed below.
+.TP
+\fB\-h\fR, \fB\-\-tabs\fR
+Output tabs instead of multiple spaces.
+.TP
+\fB\-x\fR, \fB\-\-spaces\fR
+Output multiple spaces instead of tabs.
+.It Fl l, Fl Fl lines Ar num
+.TP
+\fB\-l\fR, \fB\-\-lines\fR \fInumber\fR
+Buffer at least
+.I number
+lines in memory.  By default, 128 lines are buffered.
+.It Fl V, Fl Fl version
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Output version information and exit.
+.TP
+\fB\-H\fR, \fB\-\-help\fR
+Output help and exit.
+.SH NOTES
+The control sequences for carriage motion that
+.B col
+understands and their decimal values are listed in the following table:
+.PP
+.RS
+.PD 0
+.TP 18
+.B ESC\-7
+reverse line feed (escape then 7)
+.TP
+.B ESC\-8
+half reverse line feed (escape then 8)
+.TP
+.B ESC\-9
+half forward line feed (escape then 9)
+.TP
+.B backspace
+moves back one column (8); ignored in the first column
+.TP
+.B newline
+forward line feed (10); also does carriage return
+.TP
+.B carriage return
+(13)
+.TP
+.B shift in
+shift to normal character set (15)
+.TP
+.B shift out
+shift to alternate character set (14)
+.TP
+.B space
+moves forward one column (32)
+.TP
+.B tab
+moves forward to next tab stop (9)
+.TP
+.B vertical tab
+reverse line feed (11)
+.PD
+.RE
+.PP
+All unrecognized control characters and escape sequences are discarded.
+.PP
+.B col
+keeps track of the character set as characters are read and makes sure the
+character set is correct when they are output.
+.PP
+If the input attempts to back up to the last flushed line,
+.B col
+will display a warning message.
+.SH SEE ALSO
+.BR expand (1),
+.BR nroff (1),
+.BR tbl (1)
+.SH STANDARDS
+The
+.B col
+utility conforms to the Single UNIX Specification, Version 2.  The
+.B \-l
+option is an extension to the standard.
+.SH HISTORY
+A
+.B col
+command appeared in Version 6 AT&T UNIX.
+.SH AVAILABILITY
+The col command is part of the util-linux package and is available from
+.UR ftp://\:ftp.kernel.org\:/pub\:/linux\:/utils\:/util-linux/
+Linux Kernel Archive
