This is normal. The "open" command is an Apple-specific gadget whose
interaction with the Unix side of OSX is rather obscure. In particular,
it knows nothing about command paths in the PATH environment variable.
If you use it as
open foo
then "foo" must either be a command that exists in the current directory
or the complete path to a command. You can say "open -a TextEdit" and it
will start TextEdit, wherever that application is installed, but not
"open perl", although "perl" alone works.
Since xinvaders needs a running X11, you are lucky that "open" sometimes
understands this and starts X11 before starting the application in
question.
A better launcher for X11 applications is "open-x11". This one knows
about PATH. So you would probably have succeeded with
open-x11 xinvaders
Martin-Gohlas-Computer:~ martin$ xinvaders
bash: xinvaders: command not found
This one is indeed strange. I would have expected the error message
Error: Can't open display: :0
Maybe you would just have needed to start a new shell, that is, open a
new Terminal window after the installation of xinvaders. But, in
principle, this should not be needed for the bash shell which you are
using. Type "printenv PATH" and look whether /sw/bin appears in the
list. You showed that the pathsetup script thinks it does.
Martin-Gohlas-Computer:/sw/bin martin$ open xinvaders
the program xinvaders is started properly.
If I give the command the output ist as follows:
Martin-Gohlas-Computer:/sw/bin martin$ xinvaders
bash: xinvaders: command not found
This is because the current directory is not in your PATH. You would
have had to type
./xinvaders
Did I understand right, that there isn't only a simple command, as for
instance typing only the filename xinvaders and the program will start.
(I know this from Windows years before, where you started the program
directly because it itself was executable.) I think, it is rather
complicated, if you have to type open-x11 ... every time. Isn't there a
way to get the program startet easier?
