Check/view status of runit services.

svs checks the statuses of runit services, directly reading binary data from supervise/status of each service (so it's not a wrapper around sv). The output format is inspired by vsv. Unlike vsv, the output is more compact and more informative about statuses (not just run/down). Also, it has a quiet mode (e.g., suitable for periodic checks with cron).

Without options, svs will pretty-print the status of all services from $SVDIR or, if not set, /var/service. Indicate custom directory with -d <dir>.

The status indicators are:

• ✔ - running normally (sv: run, no paused, no want down)
• ✘ - fails (sv: down, but want up)
• ■ - stopped (sv: down, no want up)
• ▽ - finalizing (sv: finish script running)
• ⏸ - paused (sv: run or finish, but paused)
• ▼ - stopping (sv: run or finish, but want down)
• ? - cannot be checked (dangling symlink or no read permission)

The same indicators are used for corresponding logging services (if present, otherwise -).

The A column indicates if the service autostarts on boot (+, "enabled") or not (-, "disabled"), i.e. if down file is absent or present in the service directory. For log services, no indicator is shown if log is "enabled", and - is shown near the main indicator if log is "disabled".

Similar to vsv, the time elapsed since the last state change is highlighted differently for <1m, <5m, <1h ago.

With -q option, svs will perform quietly in script-friendly mode and exit with the status code, in this order:

• 1 - if no entries in service directory
• 2 - if at least one service fails
• 3 - if at least one service cannot be checked
• 0 - otherwise (each service is running, paused, stopping, finalizing or stopped)

Or, if you are happy with your package manager being unaware of svs: make + sudo make install.
