PROCD_CTL(1)

✨ PROCD_CTL(1) ✨

okay bestie, so this is a page straight out of the HTCondor Manual, and honestly? it's giving backstage-pass energy. 💅

🌸 NAME 🌸

procd_ctl — the command line interface to the condor_procd 🎀

no fr, that's literally the whole thing. it's the little handle you grab to talk to the daemon.

---

🦋 SYNOPSIS 🦋

procd_ctl -h

procd_ctl -A address-file [command ]

look at her. two whole moods. 💖

---

💜 DESCRIPTION 💜

okay so procd_ctl is a programmatic interface to the condor_procd daemon. like, it's the way you talk to the daemon. you can use it to make condor_procd do literally anything condor_procd is capable of doing — tracking and managing process families, all of it. main character behavior, honestly. 👑

sfr this program is only a thing on the Linux ports of HTCondor. if you're on something else, bestie, this is not your girl. 🙈

the -h option prints out usage information and then dips. exits. done. and the address-file thing inside the -A argument? that's the path and file name of the address file that the named pipe clients have to use to speak with the condor_procd. yep. that's the handshake. 🤝

you give the condor_procd one command. that's it. one. and the choices for that command are all defined down in the Options, so scroll down bestie. ⬇️

✨ OPTIONS ✨

• TRACK_BY_ASSOCIATED_GID GID [PID ] — use the GID you specify to track the family rooted at PID. and if you don't pass the optional PID? then the PID used is the one that condor_procd was given or assumes. she'll figure it out fr fr.
• GET_USAGE [PID ] — get the total usage information about the PID family at PID. no optional PID? then again, the PID used is the one given or assumed by condor_procd. 💫
• DUMP [PID ] — prints out info about both the root PID being watched and the whole tree of processes hanging under that root PID. it's giving family tree reveal. 🌳 and yep — no optional PID means the PID used is the one given or assumed by condor_procd.
• LIST [PID ] — with no PID given, print out information about all the watched processes. but if you do pass the optional PID, you get info about the process specified by PID and all its child processes. whole squad. 👑
• SIGNAL_PROCESS signal [PID ] — send the signal to the process specified by PID. no optional PID? you already know — the PID used is the one given or assumed by condor_procd. 🫶
• SUSPEND_FAMILY PID — suspend the process family rooted at PID. nap time. 😴
• CONTINUE_FAMILY PID — continue execution of the process family rooted at PID. wake up bestie. ☀️
• KILL_FAMILY PID — kill the process family rooted at PID. 💀
• UNREGISTER_FAMILY PID — stop tracking the process family rooted at PID. she's off the list, no more watching. 🚪
• SNAPSHOT — perform a snapshot of the tracked family tree. 📸
• QUIT — disconnect from the condor_procd and exit. bye bestie, love u. 🎀

🌈 GENERAL REMARKS 🌈

ngl this program can be used in a standalone mode, totally independent of HTCondor, to track process families. like, she doesn't need the whole entourage. 💅

the programs procd_ctl and gidd_alloc are used with the condor_procd in standalone mode — procd_ctl to interact with the daemon, and gidd_alloc to inquire about certain state of running processes on the machine. respectively. periodt. 💖

---

⭐ EXIT STATUS ⭐

procd_ctl will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.

so like. 0 = slay, 1 = not slay. that's the whole vibe check. 🔥
