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.
