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，我发现可以运行以下命令：
system_profiler SPApplicationsDataType > log.txt
这将给我一个具有以下格式的txt文件：

我希望能够获取应用程序名称和版本号，并最好以某种方式将它们存储在数组中。我不确定从哪里开始，因为所有条目对我来说都是一样的？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
MacTubes: 3.1.5
Boom: 1.6
World of Goo: 1.30
VZAccess Manager: 4.3.0
已经使用/usr/bin/awkOS X 10.9.0进行了测试。
