S6-SVDT(8)

💅 S6-SVDT(8) — your service’s death tally, served cute 💅

okay so bestie, we’re in the S6-SVDT(8) page of the System Manager’s Manual, and this one is all about the recorded death tally of a service: the list of times the process died, with the cause of death. 💀✨

🎀 NAME 🎀

s6-svdt — prints a service’s recorded death tally: the list of times the process died, with the cause of death. 🫶

🌸 SYNOPSIS 🌸

s6-svdt [-S | -s] [-n maxlines] servicedir

💖 DESCRIPTION 💖

s6-svdt prints the contents of the recorded death tally of the service being currently supervised at the servicedir s6-service-directory(7), then exits 0. No cap, it just dumps it and dips. 💅

For each recorded death, s6-svdt prints one line. That line has these fields, separated with spaces:

• A TAI64N[1] timestamp ⏰
• The word signal if the death was caused by a signal, or the word exitcode if the death was a normal exit.
• The name of the signal that caused the death, or the exit code of the process.

Want human-readable local time or GMT time instead of TAI64N timestamps? literally just pipe s6-svdt’s output into s6-tai64nlocal(8) and watch it slay. ✨

Process deaths are recorded up to a default maximum of 100. This default can be modified via the max-death-tally file in the s6-service-directory(7). 🍓

✨ OPTIONS ✨

• -S — Print signal names. This is the default. 👑
• -s — Print signal numbers. The numerical value of the signal will be printed instead of the signal name. 🔢
• -n maxlines — Limit the output to at most the latest maxlines deaths. 🎀

😭 EXIT STATUS 😭

• 0 — Success. 💖
• 100 — Wrong usage. 🙈
• 111 — System call failed. 💀
