On my Linux box with the default-for-here ksh:

    $ trap 'echo SIGWINCH' SIGWINCH
    sh: trap: bad signal SIGWINCH

On my Linux box after starting bash:

    bash-2.05b$ trap 'echo SIGWINCH' SIGWINCH
    bash-2.05b$ SIGWINCH
    bash-2.05b$ SIGWINCH
    bash-2.05b$ SIGWINCH

Nice!  Further, bash appears to update the values of LINES and 
COLUMNS after resizes by itself, so the user trap isn't even 
necessary.

On my SunOS box:

    $ trap 'echo SIGWINCH' SIGWINCH

but I don't see anything when I resize the xterm window.

On my HP-UX box:

    $ trap 'echo SIGWINCH' SIGWINCH
    $
    SIGWINCH

    SIGWINCH
    $

but I get only one "SIGWINCH" for every roughly 12 window resizings.

So I guess the answer is to run bash everywhere.

Gary
