In Leopard, pkgutil doesn't have info on all installed packages; it tracks only the new Leopard flat packages. What you have to do is first check pkgutil:

pkgutil --pkg-info <pkgid>

If that turns up nothing, you'll need to loop through all the receipts in /Library/Receipts and examine the Info.plist files:

/Library/Receipts/PackageName.pkg/Contents/Info.plist

From the Info.plist, you'll need to look at CFBundleIdentifier and CFBundleShortVersionString. Some packages also have a version.plist at /Library/Receipts/ PackageName.pkg/Contents/version.plist, which has additional version info.

There's some Python code to do all of this in munki -- http://*code.google.com/p/munki

Hello, I'm looking at creating a script to see if a package has been installed. So I have been looking through the man pages on pkgutil and installer and I dont see a logical way to join the two.

If I run "installer -pkginfo -verbose" on a pkg I get some useful information but no package identifiers or package identifier version. So what is the best approach to query pkgutil for a package if you dont have a package identifier?

thanks, Charles
