number of apps ext attrib

Valued Contributor II

Anyone have a way to run an extension attribute that returns # of applications installed?

The info is available under details in inventory lookup. It would be helpful for me if this was a searchable inventory field.

Thanks in advance.

Are you interested in all apps everywhere or just in particular places?

If you want anything from Applications (and all subfolders), then

find /Applications/ -name "*.app" | wc -l,

but is pretty slow.

If you want all and you have configured the OS to 'locate' files, then you could do

locate *.app | grep ".app$" | wc -l

If you just want apps on the system disk:

locate *.app | grep ".app$" | grep -v "^/Volumes" | wc -l

You could then further limit your hits by removing applications in the /Systems directory

locate *.app | grep ".app$" | egrep -v "^/Volumes|^/System" | wc -l

Just keep piping in the egrep to remove more lines, for example to get rid of all the lines starting /Library as well

locate *.app | grep ".app$" | egrep -v "^/Volumes|^/System|^/Library" | wc -l

Hopefully you get the idea.

As for having a searchable list, you already have one in the JSS. Advanced search > Criteria > Software Information

If you really feel for some reason that you want all of the Applications that are in /Applications listed in an EA, then you can run

ls -1 /Applications

Note, that is a number 'one' not a lower case letter L!

If you want to see all things that are called *.app in useful places like
/Applications use find etc. But if for example you want to count everything
in System Profiler this will work.

awk '/:$/ { n = NR } END { print n-1 }' < <(system_profiler

This just looks for all lines ending with a semicolon in the output
from system_profiler
SPApplicationsDataType and counts them up and then subtracts 1 for the top
where it will say "Applications:"

There are lots of ways to skin this cat based on exactly what you want.

Has anyone come up with a solution that reflects one-to-one what shows in Jamf Inventory? I talked with Jamf Support and they gave me the following:

echo "<result>ls -l /Applications/* | grep .app | grep -v "->" | wc -l</result>"

(I actually added the grep -v "->" because the results included a shortcut to Silverlight, adding the fake error filtered out that).

It does provide an app count that includes all the .apps in the /Applications folder as well as one folder deeper (i.e. /Applications/EndNoteX8/), but I found that Jamf Inventory finds a few items in folders even deeper than that (i.e. /Applications/EndNoteX8/Services/). If I change the above command too ls -l /Applications//, then it finds more than Jamf. So for one computer:

Jamf Inventory: 114 Applications

ls -l /Applications/* | grep .app | grep -v "->" | wc –l

: 106 Applications

ls -l /Applications/*/* | grep .app | grep -v "->" | wc –l

: 121 Applications

Was just wondering if anyone had cracked getting a one-to-one extension attribute to match what's in Jamf Inventory.

@el2493 Does the Mac you're running this on have Xcode installed? I found that there are embedded apps inside the path, like /Applications/ and /Applications/ and several others. These end up throwing off the totals since it looks like Jamf Pro doesn't consider these applications in it's results. From what I can tell it only looks in /Applications/ and plus one additional level deep, which includes /Applications/Utilities/ It doesn't appear to search any deeper than that.

I was able to match my own machine's results in Jamf Pro (108 installed apps) with the following 2 versions of code. First one is much shorter, but might take slightly longer to run than the mdfind one believe it or not.

find /Applications -maxdepth 2 -name *.app | awk -F'/' '{print $NF}' | sort -f

Alternately using mdfind:

mdfind -onlyin /Applications/ 'kMDItemKind == "Application"' | egrep -v "/Contents/Applications/|/Contents/Developer/" | awk -F'/' '{print $NF}' | sort -f

The egrep stuff there is necessary because unlike find, mdfind doesn't have a level limiting function, so it will drill down as many levels as it can go to find stuff.

To get the total, throw a wc -l or awk 'END{print NR}' at the end of either one.

Thanks @mm2270 , mdfind was the closest I've come to getting an exact match. Jamf Inventory shows 114 apps, mdfind shows 113 (and if I compare the 2 lists of apps, they're identical except for 1 missing app). The one app it's missing (that Jamf finds) is called, and I'm having a hard time finding where it's actually stored on the computer. It's part of the EndNote application, but a Finder search doesn't come up with anything and I've tried manually looking through the the /Applications/Endnote X8 folder as well as for EndNote and am not having any luck. I also tried searching ~/Library folder and didn't find anything.

Since this is a component of EndNote (and mdfind detects both EndNote and, which are also components of EndNote) I at least know that the app is installed and can assume this one missing .app is also installed. I think this this is probably the best I'm going to get, so thanks again!

The find command finds 111 items, so decent but not as close as mdfind.
