✨ NAME ✨

/proc/pid/auxv — exec(3) information

okay bestie, welcome to the proc_pid_auxv(5) page 💖 it's giving File Formats Manual, and it's a tiny little legend. no cap.

🦋 DESCRIPTION 🦋

okay so /proc/pid/auxv (since Linux 2.6.0) is the moment. This contains the contents of the ELF interpreter information passed to the process at exec time. literally the receipts from exec, bestie. ✨

The format is one unsigned long ID plus one unsigned long value for each entry. The last entry contains two zeros. See also getauxval(3). 🫶

🚨 permission check, bestie! Permission to access this file is governed by a ptrace access mode PTRACE_MODE_READ_FSCREDS check; see ptrace(2). Don't skip the vibe check. 💅
