I wouldn't expect any specific behavior from cat'ing a file to the screen, unless it had been formatted. That's what a pager is for - to define the behavior for unformatted text. (if grep needs an option to produce formatted text, it should take into account the destination). -- Thomas E. Dickey http://invisible-island.net ftp://invisible-island.net
