在控制台或文件中写入 Xamarin 版本信息

问题描述：

目前，要获取 Xamarin 版本信息，我们需要执行以下操作:Xamarin 工作室Xamarin Studio > 关于 Xamarin Studio > 显示详细信息 > 复制信息 [按钮]

Currently, to get Xamarin version information we need to do the following: Xamarin Studio Xamarin Studio > About Xamarin Studio > Show Details > Copy Information [button]

我需要将这些信息保存在文件中或将它们写入控制台.我们有执行此操作的命令吗?

I need to have these information in a file or writing them in a console. Do we have a command to do this?

谢谢.

获取 Visual Studio for Mac 版本:

To get Visual Studio for Mac version:

/usr/libexec/PlistBuddy -c 'print :CFBundleVersion' /Applications/Visual\ Studio.app/Contents/Info.plist

获取当前使用的 Mono 版本:

To get currently used Mono version:

mono --version

或者您可以查看当前版本链接到的内容:

or you can look at what current version links to with:

la /Library/Frameworks/Mono.framework/Versions/Current

类似于 Xamarin.iOS 和 Xamarin.Android 框架:

Similar for Xamarin.iOS and Xamarin.Android frameworks:

la /Library/Frameworks/Xamarin.Android.framework/Versions/Current
la /Library/Frameworks/Xamarin.iOS.framework/Versions/Current

如果您只想要 la 命令的版本，您可以使用 | 对命令进行后缀.sed 's/^.*->//g'.这将替换 -> 之前的所有内容，包括该箭头，因此它只会显示版本号.所以像:

If you only want the version from the la commands you can postfix the commands with | sed 's/^.*-> //g'. This will replace everything before the -> including that arrow with nothing, so it will only display the version number. So something like:

la /Library/Frameworks/Xamarin.iOS.framework/Versions/Current | sed 's/^.*-> //g'

会给 11.4.0.93.

对于 Mono.framework 来说，它是一个绝对路径，因此您可以再次通过管道传递到 sed 's!.*/!!' 以获取文件名":

For the Mono.framework one, it is an absolute path, so you can pipe again to sed 's!.*/!!' to just get the "filename":

la /Library/Frameworks/Mono.framework/Versions/Current | sed 's/^.*-> //g' | sed 's!.*/!!'

将所有这些添加到脚本中:

Add all this to a script:

#!/usr/bin/env bash

mono_version=$(ls -n /Library/Frameworks/Mono.framework/Versions/Current | sed 's/^.*-> //g' | sed 's!.*/!!')
vs_version=$(/usr/libexec/PlistBuddy -c 'print :CFBundleVersion' /Applications/Visual\ Studio.app/Contents/Info.plist)
ios_version=$(ls -n /Library/Frameworks/Xamarin.iOS.framework/Versions/Current | sed 's/^.*-> //g')
android_version=$(ls -n /Library/Frameworks/Xamarin.Android.framework/Versions/Current | sed 's/^.*-> //g')
echo "mono:" $mono_version
echo "vs version:" $vs_version
echo "ios version:" $ios_version
echo "android version:" $android_version

记得在 .sh 文件上运行 chmod +x.然后你可以用 sh version.sh 运行它，它会吐出来:

Remember to run chmod +x on the .sh file. Then you can run this with sh version.sh and it will spit out:

mono: 5.4.1
vs version: 7.3.0.708
ios version: 11.4.0.93
android version: 8.1.0-21
