COL(1)			     BSD Reference Manual			COL(1)

NAME
     col - filter reverse line feeds from input

SYNOPSIS
     col [-bfhx] [-l num]

DESCRIPTION
     col filters out reverse (and half-reverse) line feeds so that the output
     is in the correct order with only forward and half-forward line feeds,
     and replaces whitespace characters with tabs where possible. This can be
     useful in processing the output of nroff(1) and tbl(1).

     col reads from the standard input and writes to the standard output.

     The options are as follows:

     -b	     Do not output any backspaces, printing only the last character
	     written to each column position.

     -f	     Forward half-line feeds are permitted ("fine" mode). Normally
	     characters printed on a half-line boundary are printed on the
	     following line.

     -h	     Compress spaces into tabs. This is the default behavior.

     -x	     Output multiple spaces instead of tabs.

     -l num  Buffer at least num lines in memory. By default, 256 lines are
	     buffered.

     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-10	      Half reverse line feed (escape then 10).
     ESC-11	      Half forward line feed (escape then 11).
     backspace	      Moves back one column (8); ignored in the first column.
     carriage return  Move back to first column (13).
     newline	      Forward line feed (10); also does carriage return.
     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 unrecognised 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.
