OK, "launch path not accessible" in the run log. I take back
everything I said. Obviously I need to rethink this. I would like
the user to be able to include a script file without having to make
it executable. Earlier, I had a look to see if there is a way to
determine whether is file is executable, but didn't find one. I
suppose there must be a way but didn't see it in NSFileManager or
NSWorkspace.
Ron,
Take a look at the shell's "source" command, which will load and
execute
commands from a text file with no other requirements:
source file.txt
This might give you an additional option. Perhaps you can check to
see if
the file is executable and/or if it includes the shebang. If not,
then
conclude it's merely a text file containing shell commands and pass
it along
to "source" to run.
But here's something interesting: according to a simple "hello
world" script
I just tested, source will even handle text files that have execute
permission set and contain a shebang (ie, real scripts). If that
turns out
to be true in general, then you can let the source command execute
anything
designated as a script by the user. I'd recommend testing it out.

Well that sounds pretty interesting. I don't have the energy to
investigate it right now (too much to do!), but I certainly will look
at "source" as a generic script runner. When you say "shell", which
one do you mean?
Ron
