This email sent to site_archiver@lists.apple.com Yes, but we were discussing the fragility of parsing tool output. OK, well, that's an easy discussion: Don't do that. popen of lsof will work, assuming you use the output format specifiers to prevent it from changing output format on you, or simply look at the found/not fond return value. The point of forcing you to write wrappers around standard tools instead of doing what the tool does is to ensure you that when the system is updated, you are guaranteed that the tools are updated at the same time that the kernel and other system components are updated, so your code will continue working, even if we change the system interface used by the tool. Jordan, unless I'm mistaken, you're saying don't do what Terry said to do. smime.p7s
