What's the error?
Some systems have a too-small limit (like 16 or 32) on the number of
characters that can be used in the name of the command.
One workaround is to create a symbolic link or shell script somewhere
else in the filesystem that will allow you to bypass the limit.
Another is to put Octave in your PATH and use something like
#! /usr/bin/env octave
except then you probably won't be able to pass options in addition to
the command name. If you need to do that, then you can use a wrapper
shell script that calls Octave with the options.
BTW, I don't think Octave can fix any of these problems. They are all
limitations of the OS.
