Less normally allows you to change command-line options from within a less session (just type "-" followed by the option...). However, they seem to have intentionally disabled this feature with the "-X" option. I think the reason probably is that once you're inside the less session, it's too late to change -- the "terminal init" command has already been sent (or not sent), and if a program has sent the "terminal init" command, technically it _has_ to send the "terminal deinit" command when it exits, otherwise the terminal will be left in a potentially screwed up state. [E.g., at least one 'terminal init" I've seen (in the past -- I don't know if xterm works this way) moved the display window to the beginning of the scrollback buffer; "terminal deinit" would then move the display window back to the end of the scrollback buffer. If deinit isn't sent, things would be weird once the terminal starts scrolling again -- not only would new output overwrite the scrollback buffer from the beginning, but new lines that appeared at the bottom when the terminal scrolled would not be blank!] For this reason, probably a "x" command _is_ impossible (or at least, would often yield screwy results when you used it). -Miles -- Occam's razor split hairs so well, I bought the whole argument! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
