"hello world" launchd plist not working

Question

I have the following plist file at ~/Library/LaunchAgents: ``` Label com.yogapo.test_launchd Program . /Users/luke/dev/data_yogapo/script/test_launchd.sh StartInterval 10 RunAtLoad ``` And the test_launchd.sh file is contains the following: ``` #! /bin/bash echo "hello world from test_launchd.sh" >> /Users/luke/dev/data_yogapo/log/development.log ``` When I run test_launchd.sh manually with `. /Users/luke/dev/data_yogapo/script/test_launchd.sh` the results are as expected: the line appears at the end of `development.log` But when I load up this plist file, nothing happens: ``` $ cd ~/Library/LaunchAgents $ launchctl load com.yogapo.test_launchd.plist $ launchctl list | grep yogapo - 1 com.yogapo.t…

Accepted Answer

You are asking `launchd` to run progam called ``` ". /Users/luke/dev/data_yogapo/script/test_launchd.sh" ``` It will take the entire value of the `Program` key as the first argument to `execvp`(see man execvp(3) for more details) If you were to examine the `system` log, you would see something like: May 22 21:17:38 dented com.apple.launchd.peruser.501[202] (com.yogapo.test_launchd[32986]): posix_spawn(". /Users/luke/dev/data_yogapo/script/test_launchd.sh", ...): No such file or directory May 22 21:17:38 dented com.apple.launchd.peruser.501[202] (com.yogapo.test_launchd[32986]): Exited with exit code: 1 `launchd` is not a shell. However, it can interpret hash-bang character sequences to identify which program to use to interpret your script. Therefore, simply specify your script as the program to run: ``` Program /Users/luke/dev/data_yogapo/script/test_launchd.sh ``` Note: Should you need to pass arguments to your script, use the `ProgramArguments` key instead and put the whole command line there. For example: ``` ProgramArguments /Users/luke/dev/data_yogapo/script/test_launchd.sh arg1 arg2 arg3 ```
