> I started, as I usually do, by searching for the term “chdir” using the GitHub search bar. That's not bad, but I'd also suggest checking man pages for syscalls. `man 2 chdir` will give the some documentation on both Mac and Linux OSes and call out the specs that are relevant to the call. (Why `man 2`? That searches section 2 of the man pages which is dedicated to syscalls. How on earth would someone know that? `man man` of course. :-) ) On linux, an interesting thing is that you can inspect a process's current working directory (IE the last thing they chdir()ed to) by looking in /proc/<pid>/cwd/. It presents itself as a symlink to the actual current directory as stored in the kernel. |
