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，我发现我可以运行这个命令：

system_profiler SPApplicationsDataType > log.txt

这会给我一个txt文件，格式如下：

Applications:

AppleTalk:

我希望能够获取应用程序名称和版本号，并以某种方式最好将它们存储在一个数组中。我不知道从哪里开始，因为所有条目对我来说都一样？我也需要忽略没有版本号的条目。

这是一个 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可以运行

awk -f script.awk log.txt

得到像这样的输出

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

这已经通过/usr/bin/awkOS X 10.9.0 的测试。
