nx_proc_ctl_cmdl.nx

nx_proc_ctl.nx -- canonical sovereign process control: kill by FULL /proc/<pid>/cmdline. THE one true copy that replaces (a) nx_proc_kill.nx's /proc/<pid>/comm match -- the 15-char-TRUNCATED field that silently matched nothing for long names = the 2026-06-29 gallery-login disaster -- and (b) the buried-in-nx_hostctl hc_kill_by_cmdline. IMPORTABLE (no main, no self-test). Matches "/"+name -> the binary PATH, never an arg mention (so it can't kill its own command line); signal is a parameter (9=SIGKILL, 15=SIGTERM); returns the HONEST killed count (0 => nothing matched => the op did nothing). Bounded reader (fixed reused buffers; no sys_read_file 4GiB-per-call leak). license_tier: ORIGINAL
