Run command on startup / login (Mac OS X)

Question

I was not sure if this was for StackOverflow or here, I settled for here. I was wondering which file I should place this bash command in so it will be run on startup.

# Start the MongoDB server
/Applications/MongoDB/bin/mongod --dbpath /usr/local/mongo/data --fork --logpath /usr/local/mongo/log

I have been scouring the net and think it is between ~/.bashrc, ~/profile, /etc/bashrc, /etc/profile or ~/.bash_profile. Although I have tried these and they seem to run on terminal startup not Mac startup. Am I missing a file here?

Thanks for any help you can give.

Answer 1

Officially none of these. The Apple suggested wat is to use launchd a Gui to set this up is lingon

As for the files you mention the ones in the home directory ~/.bashrc, ~/profile, ~/.bash_profile are only started when you login via a terminal.

EDIT: The ones in /etc are run by the shell starting for all users before the one in home directory. bash manual

The Unix startup script involved /etc/rc* but for OSX just use the launchd stuff

You will have to look at how launchd and launchctl work on MacOS. You could start by reading the man pages for both the commands. You could then look inside /Library/LaunchAgents/ and /Library/LaunchDaemons/ for examples of how to set up applications to load at different times through the launchctl interface.

Here's an example I found on Stack Overflow that might help you further.

To run a command on start up on OS X, you need to use launchd.

If you don't want to use Lingon, you need to create a launchd Property List. This is an XML file, so you can do it with your favourite text editor or alternatively you can use the Property List Editor that's installed with the Mac OS X Dev Tools. Create the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>some.meaningful.name</string> <!-- org.mongodb.mongodb perhaps? -->

    <key>OnDemand</key>
    <false/>

    <key>UserName</key>
    <string>anAppropriateUser</string>

    <key>GroupName</key>
    <string>anAppropriateGroup</string>

    <key>ProgramArguments</key>
    <array>
            <string>/Applications/MongoDB/bin/mongod</string>
            <string>--dbpath</string>
            <string>/usr/local/mongo/data</string>
            <string>--fork</string>
            <string>--logpath</string>
            <string>/usr/local/mongo/log</string>
    </array>
</dict>
</plist>

Save this in /Library/LaunchAgents/some.meaningful.name.plist (you will need an administrator account and/or sudo), then open a terminal and do:

sudo launchctl load /Library/LaunchAgents/some.meaningful.name.plist

This will cause launchd to load the item which will cause it to start MongoDB on boot. As a bonus, launchd will monitor it and, if it exits for any reason, it will be re-started. To get rid of the item simply replace load in the above command with unload.
