正在将应用程序日志文本文件解析为数组

Question

好的，这就是问题所在。我正在尝试获取一系列已安装的应用程序和版本。

到目前为止，我发现我可以运行以下命令：

system_profiler SPApplicationsDataType > log.txt

这将给我一个如下格式的txt文件：

我希望能够获得应用程序名称和版本号，并以某种方式将它们存储在数组中。我不知道从哪里开始，因为所有的条目在我看来都一样？我也需要忽略没有版本号的条目。

Answer 1

这里有一个Awk脚本，它将为您提供您提到的输出格式：

/^ {4}.+:$/ {
    sub(/^ {4}/, "", $0)
    last_application = $0
}
/^ +Version:/ {
    sub(/^ +Version: /, "", $0)
    print last_application " " $0
}

如果您将其保存为script.awk，则可以运行

awk -f script.awk log.txt

以获得类似的输出

MacTubes: 3.1.5
Boom: 1.6
World of Goo: 1.30
VZAccess Manager: 4.3.0

这已经用OSX10.09.0的CCD_ 2进行了测试。
