How can I add arguments to OSX launchd plist to pipe output to a log file?

Question

I have tried many different variation on this but just can\'t get it to work.

I have a plist file:

Answer 1

The standard out and error keys are very useful, I redirected mine to the first terminal/shell as follows:

StandardOutPath
/dev/ttys000
StandardErrorPath
/dev/ttys000

You can change ttys000 to another number (ttys001..2) if you have multiple terminals. You can find the terminal id by typing in the shell:

tty

This helped me to find out why I was getting console errors in OS X, I needed to have the full path for every command and full paths for directories I was CD'ing to in scripts.

for instance grep is:

/usr/bin/grep

and commands installed by macports use other paths also, like:

/opt/local/bin/lynx

I also tried to chown root:wheel the plist, but this doesn't seem to be necessary, but probably not a bad idea to prevent someone from editing it to whatever...

edit:changed mine back to normal user after I got some permission errors which turned out to be because the script was trying to make files in / without permission, needed to add full paths to output files too, which is weird as it worked the previous day.
