Mac OS X: Octave and Gnuplot> sh: gnuplot: command not found

alias
gnuplot="/Applications/gnuplot/Gnuplot.app/Contents/Resources/bin/gnuplot"
alias
octave="/Applications/gnuplot/Octave.app/Contents/Resources/bin/octave"
Gnuplot plots very nicely. Octave runs and does all non-graphical things I

The alias command sets up a variable that applies only in your shell.
It won't help octave find gnuplot. You probably need to set up a symbolic
link to gnuplot in some directory on your path. Try:

ln -s /Applications/gnuplot/Gnuplot.app/Contents/Resources/bin/gnuplot \
/usr/local/bin/gnuplot

If this complains about permission precede this with a sudo and enter your
password when prompted.

Or, add the directory containing gnuplot to your PATH before starting
Octave. In your .profile:

PATH=$PATH:/Applications/gnuplot/Gnuplot.app/Contents/Resources/bin

Or, use

gnuplot_binary ("/Applications/gnuplot/Gnuplot.app/Contents/Resources/bin/gnuplot");

in Octave. But probably setting PATH is better because then you can
also start Octave from the shell.

Ahem, sorry but the very best idea is to move Gnuplot.app into the /Applications
folder and not into a /Applications/gnuplot folder and let do Octave.app all the
rest for you that is necessary (ie. you don't set a alias, a path or
gnuplot_binary). BTW, all that (how to set up Gnuplot.app into a directory other
then /Applications if really necessary) is explained in the README.html file of
the octave-X.X.X-i386.dmg and octave-X.X.X-ppc.dmg virtual disc images... Please
have a look at it...

THANKS a lot- i had totally forgotten about the link in /usr/local/bin. That
works splendidly!
Cheers,
