First of all please forgive me for my ignorance. I'm not sure if this is possible.

I might be playing around and installed a lot of software, tools, databases or servers or services such as macports, php, etc. Over a period of time I might forget what I've put in and there maybe a lot of stuff I dosen't need anymore. Is there any way or Terminal command that allow me to check what is there?

It's pretty much impossible, since you can place applications just about anywhere you like. Additionally, what constitutes an "application" might be debatable — does a two-line shell script count?


Regular applications are usually located in /Applications, ~/Applications (for every user).

Widgets are in ~/Library/Widgets (every user) or /Library/Widgets(unusual, system-wide).

Preference Panes are in /Library/PreferencePanes(all users) or ~/Library/PreferencePanes (every user)

These are basically the things you'd install manually.


If you installed something using a regular installer, this has been logged to /Library/Receipts(installer Receipts and the InstallHistory.plist log file).


If you're using Homebrew, Fink, or MacPorts Unix package managers, they keep track of what they installed. Look up their documentation.


If you installed something manually (QuickLook plugins come to mind), or compiled something yourself, then you're basically out of luck.

Fear not!

man hier 

Will show you where things should be. And where they should not be, such as installed into /Users/Shared, eh Adobe?

To my knowledge, everything that is installed via the OS X package installed (.pkg or .mpkg) is tracked in /Library/Receipts/InstallHistory.plist. As far as drag and drop installs, you would have to trawl through the file system to look for those.

You could issue a command such as find / -type d -name MacOS which would indicated some sort of bundle in OS X, but the risk there is that you identify frameworks and system files and such.

Understood! Thanks guys. –  Jeno Jun 14 '11 at 18:56
    
Can I edit the InstallHistory.plist manually to remove stuff that I dosen't want anymore? –  Jeno Jul 12 '11 at 9:26
    
I'm not sure what you would hope to accomplish. The .plist file is simply a list of what was installed -- a registry of sorts. Editing it will not remove any software. –  Kirk Jul 19 '11 at 13:52
