✨ NAME ✨

function::ns_pid — returns the ID of a target process as seen in a pid namespace 🦋

like, the ID of a target process as seen in a pid namespace. that's the whole vibe. no cap.

---

✨ SYNOPSIS ✨

ns_pid:long()

she takes nothing, she returns a long. iconic behavior honestly 💅

---

✨ ARGUMENTS ✨

None.

literally zero. no args, no drama, no nothing. she simply does not need your input 🙈

✨ DESCRIPTION ✨

This function returns the ID of a target process as seen in the target pid namespace.

so, real talk: a process can have a whole different ID depending on which pid namespace you're looking at it from — ns_pid hands you the one from the target pid namespace, not whatever the host is seeing. it's giving "same process, different era" ✨
