Data Cannot run UNIX executable !

I have installed the Darwin Calendar Server on my Mac and got it working.

To start the server I open a Finder window on my mac and click the UNIX executable called RUN.

In order to start the server automatically on bootup I used LINGON to add a startup Daemon to call "RUN -d". When I reboot the server does not start.

The daemon does exist in /Library/LaunchDaemons and the startup string is correctly described, i.e. right path and command. Looking at the logs I find that MAC OS has tried to start the daemon but come up with "command not found".

If I open a Terminal window, navigate to the correct directory and then type "run" I get exactly the same error... "command not found" although an ls shows it IS there. I have tried logging on as ROOT, (sudo tcsh), but still have the same problem so it is not an authority issue it seems.

Can somebody please help.... a) Why can I not run my UNIX executable from Terminal. (There is another UNIX executable that does seem to run). b) if I can get it to run then my startup daemon should run too !?

Many thanks in advance....

Hi Alex,

Since you have the run command in ur path. The problem might be in assigning the path variable. There are 2 ways.

1. Run the command by giving the full path like

/../.../run -d

2. You have to set path variable in PATH of your profile by


Run the profile and execute the command

Thanks for your suggestions...

I did check the path variable and it looks like this:


...which I think has everything I need !?

I also try running the command using the full path "/mydir/another/run -d" and I get the error "No such file or directory". In fact this is exactly how the daemon specifies the command i.e. with the full path string. It is this daemon that is failing to start.

Any other suggestions ? I tried a simple "Hello World" BASH script and it comes up with "command not found" when called from the directory in which it lives. I have made it executable and Mac OS X recognizes as a UNIX executable !?

Does command "run" is a unix executable file ,

Try this ....export PATH
and execute the . profile by . ./.profile

and then try to execute the command.

Can u just ls -ltr of the directory in which run command sits and output here so that we can see it....

Thanks for your suggestions...

I could not find .profile on my Mac. There is /etc/profile which looks like this:

# System-wide .profile for sh(1)

if [ -x /usr/libexec/path_helper ]; then
eval `/usr/libexec/path_helper -s`

if [ "${BASH-no}" != "no" ]; then
[ -r /etc/bashrc ] && . /etc/bashrc

If you can tell me where to find it or what the equivalent is on the Mac that would be useful. The path looks to be OK so the shell seems to be inheriting the correct settings but from where I don't know !?

The direcrtory listing "ls -ltr" looks like this:

MacTwo:calendarserver alex$ ls -ltr

Incidentally, does anyone know what the significance is of the "@" in the output of "ls" ?

Thanks for your reply....

Yes I did check to make sure the executable bit was correctly set. The program is called "run" and as far as I am aware I did chmod it correctly as the listing above shows !?

I really need to crack this one so any other ideas would be gratefully received !
