System Manager's Manual 💖 svc(8) — bestie, this is the little command that tells your services what to do. 👑

---

🌸 NAME 🌸

svc — controls services monitored by supervise(8). 💅

---

🎀 SYNOPSIS 🎀

svc [ -udopchaitkx ] services

---

🦋 DESCRIPTION 🦋

okay so services is literally just any number of arguments, and each argument names a directory used by supervise(8). that's it, that's the whole vibe. ✨

and svc applies all the options to each service in turn — like, every single service gets the same treatment, no favorites. 🫶

---

💖 OPTIONS 💖

• -u — Up. if the service isn't running, start it. and if the service stops? restart it. keep it alive, main character energy. 🔥
• -d — Down. if the service is running, send it a TERM signal and then a CONT signal. after it stops, do not restart it. it's over, periodt. 💀
• -o — Once. if the service isn't running, start it. do not restart it if it stops. one and done, no encore. 🎀
• -p — Pause. send the service a STOP signal. ✋
• -c — Continue. send the service a CONT signal. okay keep going bestie 💖
• -h — Hangup. send the service a HUP signal. 📞
• -a — Alarm. send the service an ALRM signal. ⏰
• -i — Interrupt. send the service an INT signal. 🙈
• -t — Terminate. send the service a TERM signal. 🛑
• -k — Kill. send the service a KILL signal. no cap, this one does not play. 💀
• -q — Quit. send the service a QUIT signal. 🚪
• -1 — send the service a USR1 signal. 1️⃣
• -2 — send the service a USR2 signal. 2️⃣
• -x — Exit. supervise(8) will exit as soon as the service is down.

🚨 okay real talk about -x: if you use this option on a stable system, you're doing something wrong. supervise(8) is designed to run forever. it's giving "why would you do that" energy. 😭
