如何使用plutil移除plist文件中的指定键？解决执行命令时的报错问题

Let's break down what's going wrong here and fix it step by step:

Why You're Seeing That Error #

Your plist file has a critical XML syntax mistake in the first line:

<?xmlversion="1.0"encoding="UTF-8"?>

This line is missing required spaces between XML attributes. The correct format should be:

<?xml version="1.0" encoding="UTF-8"?>

plutil is extremely strict about valid XML formatting for plist files, so this tiny syntax error causes it to fail parsing entirely, hence the "unknown tag" and JSON parsing errors (it falls back to JSON parsing when XML fails).

Step-by-Step Fix #

1. Repair the plist File's Syntax #

First, fix the broken first line of your plist. Open the file in any text editor and update the first line to:

<?xml version="1.0" encoding="UTF-8"?>

The rest of your plist content looks valid, so no other changes are needed here.

If you prefer a command-line fix, you can use sed to patch the first line automatically:

sed -i '' '1s/xmlversion/xml version/;1s/encoding/ encoding/' your-file-name.plist

2. Run the Correct plutil Remove Command #

With the plist file fixed, run this command to remove the WildcardTicketToRemove key and its associated value:

plutil -remove WildcardTicketToRemove your-file-name.plist

For older versions of plutil that require explicit format specification, add the -convert xml1 parameter to ensure it handles the XML plist correctly:

plutil -convert xml1 -remove WildcardTicketToRemove your-file-name.plist

3. Verify the Change #

Confirm the key was removed by printing the plist content:

plutil -p your-file-name.plist

You should see the output no longer includes the WildcardTicketToRemove key and its <data> value.
