There are also the xcodebuild and xcode-select files in /usr/bin I need to know if the command line tools is installed. Is there a command for it?

只需在命令行中输入gcc或make！ OSX将知道您没有命令行工具，并提示您安装它们！

Just enter in gcc or make on the command line! OSX will know that you do not have the command line tools and prompt you to install them!

要检查它们是否存在，xcode-select -p将打印目录.或者，如果返回值不存在，则返回值为2，如果不存在，则返回值为0.只需打印返回值(感谢@Andy ):

To check if they exist, xcode-select -p will print the directory. Alternatively, the return value will be 2 if they do NOT exist, and 0 if they do. To just print the return value (thanks @Andy):

xcode-select -p 1>/dev/null;echo $?

使用pkgutil --pkg-info=com.apple.pkg.CLTools_Executables

选项1: Rob Napier 建议使用pkgutil --pkg-info=com.apple.pkg.DeveloperToolsCLI，即可能更干净.

Option 1: Rob Napier suggested to use pkgutil --pkg-info=com.apple.pkg.DeveloperToolsCLI, which is probably cleaner.

选项2:.在/var/db/receipts/com.apple.pkg.DeveloperToolsCLI.plist内部检查对com.apple.pkg.DeveloperToolsCLI的引用，它将列出版本4.5.0.

Option 2: Check inside /var/db/receipts/com.apple.pkg.DeveloperToolsCLI.plist for a reference to com.apple.pkg.DeveloperToolsCLI and it will list the version 4.5.0.

    InstallDate = "2012-12-26 22:45:54 +0000";
    InstallPrefixPath = "/";
    InstallProcessName = Xcode;
    PackageFileName = "DeveloperToolsCLI.pkg";
    PackageGroups =     (

        "com.apple.DevToolsBoth.pkg-group",
        "com.apple.DevToolsNonRelocatableShared.pkg-group"
    );
    PackageIdentifier = "com.apple.pkg.DeveloperToolsCLI";
    PackageVersion = "4.5.0.0.1.1249367152";

        System = "!#acl 1\\ngroup:ABCDEFAB-CDEF-ABCD-EFAB-CDEF0000000C:everyone:12:deny:delete\\n";
