KeyChain Security 命令行工具适用于 find-internet-passwords，但不适用于 find-generic-passwords
研究使用 KeyChain 的命令行工具。我可以通过安全来做很多事情；列出我的多个钥匙串，转储它们并设置默认值。 找到我的密码
阅读教程和其他帖子，我希望通过security find-generic-password test
，但我得到
安全：SecKeychainSearchCopyNext：在钥匙串中找不到指定的项目。
这在我的默认钥匙串或 login.keychain 中不起作用。但是，我可以使用 find-internet-password 命令找到列为“internet”的密码。谁能解释为什么或我做错了什么？我一直在阅读的网站是手册页和 http://blog.macromates.com/2006/钥匙串访问 shell/,
Looking into using the command line tool for KeyChain. I am able to do a lot of the things through security; listing my multiple keychains, dumping them and setting defaults. Reading through tutorials and other postings I expect to find my passwords with
security find-generic-password test
But I get
security: SecKeychainSearchCopyNext: The specified item could not be found in the keychain.
This won't work in my default keychain or login.keychain. However, I am able to find my passwords listed as 'internet' with find-internet-password command. Can anyone explain why or what I am doing wrong? Sites I've been reading is the man page and http://blog.macromates.com/2006/keychain-access-from-shell/,

通用密码由其服务和帐户属性标识。例如，要搜索“foo”服务的帐户“bar”的密码，请使用
-g选项在输出末尾显示密码值。服务和帐户的组合保证唯一地标识特定密码。其他查询（注释、标签等）也是可能的，但它们可能匹配多个密码。
find-generic-password仅显示第一个匹配项，这限制了它对于此类查询的有用性。Generic passwords are identified by their Service and Account attributes. For example, to search for a password for account "bar" of the "foo" service, use
The
-goption displays the value of the password at the end of the output.The combination of service and account is guaranteed to uniquely identify a particular password. Other queries (comment, label, etc.) are possible, but they may match multiple passwords.
find-generic-passworddisplays only the first single matching item, which limits its usefulness for such queries.如果您只需要密码，更准确和最新的答案是使用
-w而不是-g。我见过人们使用-g并使用 awk/perl 解析输出来获取密码字段，而这是不需要的（不再需要）。您需要做的就是：
您可以使用
find-internet-password而不是find-generic-password命令，具体取决于您的密码在钥匙串中的存储位置。A more accurate and up to date answer would be to use
-winstead of-gif you only need password. I've seen people using-gand parsing output using awk/perl to get the password field, which is not needed (anymore).All you need to do is:
You may use
find-internet-passwordinstead offind-generic-passwordcommand depending on where your password is stored in keychain.
