如何使用 plutil 获取值?
how to use plutil to get a value?
我需要获取“ProductVersion”的值并输出:“15.1”
我有 plutil 的版本,但无法获取值
plutil -key ProductVersion myfile //不工作
这是我的文件内容:
<?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>
plutil 的帮助:
-help Print this message
-full Print an exhaustive list of options
-verbose Show verbose output
-show Show property list data
-keys List top level dictionary keys
-create Create a new empty property list
-key keyname Recover value for key. Multiple uses builds keypath
-value value Set value for keypath
-remove Remove value at keypath
-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
您的 plist 文件格式不正确;结束 </dict>
标签重复。这需要修复。
macOS 12.3 附带的 plutil
没有 -key
选项(不再),但您可以使用 PlistBuddy
:
/usr/libexec/PlistBuddy -c "Print :ProductVersion" myfile
这是在 Mac OS 12.3.
上使用 plutil 从 plist 文件获取值的方法
plutil -extract "ProductVersion" raw myfile
如果你需要知道值的类型,你可以先做:
plutil -type "ProductVersion" my file
