how to use plutil to get a value?-CodePudding

I need get value of "ProductVersion" and output: "15.1" I have versions of plutil, but can't get the value

plutil -key ProductVersion myfile //not working

here is the myfile content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
      <key>ProductVersion</key>
        <string>15.1</string>
        <key>SystemImageID</key>
        <string>3DD7870B-96BB-4BA1-9C54-306734147FFE</string>
        <key>Version</key>
        <string>Version</string>
    </dict>
</dict>
</plist>

-type typeid            Type to use while setting key. Valid types are int,
                        float, bool, json, and string (default). Use json to
                        define arrays and dictionaries
-convert format         Convert each property list file to selected format.
                        Formats are xml1 and binary1 and json. Note that json
                        files are saved to filename.json

CodePudding user response：

Your plist file is malformed; the closing </dict> tag is duplicated. This needs to be fixed.

plutil as shipped with macOS 12.3 does not have a -key option (anymore), but you can use PlistBuddy:

/usr/libexec/PlistBuddy -c "Print :ProductVersion" myfile
