descriptionRunit service manager CLI
Dave Eddy (bahamas10)



vsv - Void Service Manager

Manage and view runit services.

Note: This is a rewrite in Rust of vsv which was originally written in Bash.

vsv was inspired by vpm. vsv is to sv as vpm is to the xbps-* commands.


Using crates

cargo install vsv

Compile yourself

git clone git@github.com:bahamas10/rust-vsv.git
cd rust-vsv
cargo build


Run vsv without any arguments to get process status. This is equivalent to running vsv status:


Note: sudo or escalated privileges are required to determine service state because of the strict permissions on each service's supervise directory.

vsv scans the /var/service directory by default, which can be overridden by setting the $SVDIR environmental variable or passing in a -d <dir> argument. Any service that has been in a state for less than 5 seconds will be marked in red and any less than 30 seconds will be marked in yellow, making new or failing services easy to spot:


We can isolate the service by passing it as a "filter" to status.


A string can be passed as the first argument after status to filter for services that contain that string in their name. Also, -t can be supplied to status to print the process tree of the pid for that process:


Any command other than status will be passed directly to the sv command. Restarting a service is as easy as vsv restart <svc>:


To stop a service, vsv down <svc> or vsv stop <svc> can be used:


A full service tree can be generated with vsv -t. This command is equivalent to running vsv status -t:


-l can be specified to view log services for each service as well. This command is equivalent to running vsv status -l virt:


-t can be specified with -l to view log services as a tree for each service as well as normal services. This command is equivalent to running vsv status -tl virt:



Quick Examples:

  • vsv - show all services
  • vsv status - same as above
  • vsv stop <svc> - stop a service
  • vsv start <svc> - start a service
  • vsv restart <svc> - restart a service
  • vsv enable <svc> - enable a service (autostart at boot)
  • vsv disable <svc> - disable a service (no autostart at boot)
  • vsv hup <svc> - refresh a service (SIGHUP)


The status subcommand has the following fields:

  • SERVICE - the service (directory) name.
  • STATE - the service state: output from .../$service/supervise/stat.
  • ENABLED - if the service is enabled (lacks the .../$service/down file).
  • PID - the pid of the process being monitored.
  • COMMAND - arg0 from the pid being monitored (first field of /proc/$pid/cmdline.
  • TIME - time the service has been in whatever state it is in.

Command Usage:

$ vsv -h

vsv 2.0.0
Runit service manager CLI


    -c, --color <yes|no|auto>    Enable or disable color output
    -d, --dir <dir>              Directory to look into, defaults to env SVDIR or /var/service if
    -h, --help                   Print help information
    -l, --log                    Show log processes, this is a shortcut for `status -l`
    -t, --tree                   Tree view, this is a shortcut for `status -t`
    -u, --user                   User mode, this is a shortcut for `-d ~/runit/service`
    -v, --verbose                Increase Verbosity
    -V, --version                Print version information

    disable    Disable service(s)
    enable     Enable service(s)
    help       Print this message or the help of the given subcommand(s)
    status     Show process status

Any other subcommand gets passed directly to the 'sv' command, see sv(1) for
the full list of subcommands and information about what each does specifically.
Common subcommands:

    start <service>           Start the service
    stop <service>            Stop the service
    restart <service>         Restart the service
    reload <service>          Reload the service (send SIGHUP)

Environmental Variables:

  • SVDIR: The directory to use, passed to the sv command, can be overridden with -d <dir>.
  • PROC_DIR: A Linux procfs directory to use for command name lookups, defaults to /proc.
  • SV_PROG: The command to use for any "external" subcommand given to vsv, defaults to sv.
  • PSTREE_PROG: The command to use to get a process tree for a given pid, defaults to pstree.
  • NO_COLOR: Set this environmental variable to disable color output.
