proc_pid_cwd(5)

๐Ÿ’– proc_pid_cwd โ€” the group chat version ๐Ÿ’–

okay so this is proc_pid_cwd(5) from the File Formats Manual, and bestie, it's a short one but it's so useful. let's get into it ๐Ÿฆ‹


โœจ NAME โœจ

/proc/pid/cwd โ€” a symbolic link to the current working directory ๐Ÿ‘‘


๐ŸŒธ DESCRIPTION ๐ŸŒธ

  • /proc/pid/cwd โ€” this is a symbolic link to the current working directory of the process. that's it. that's the whole vibe. it's just a lil pointer to where that process is standing right now ๐ŸŽ€

so like, say you wanna know where process 20 is hanging out. you can literally just do this:

$ cd /proc/20/cwd; pwd -P

and boom, pwd -P tells you the real path, no symlink games. iconic. ๐Ÿ’…

โš ๏ธ okay important caveat for the multithreaded girlies: in a multithreaded process, the contents of this symbolic link are not available if the main thread has already terminated (typically by calling pthread_exit(3)). so if main thread dipped, this link is giving nothing. ๐Ÿ˜ญ

also, permission-wise: whether you're allowed to dereference or read (readlink(2)) this symbolic link is governed by a ptrace access mode PTRACE_MODE_READ_FSCREDS check. see ptrace(2). so it's not just your perms, it's the ptrace access mode rules. iykyk ๐Ÿ”ฅ
