There is no status bar or other decoration initially; these are instead clients that can be run within the Wayland session. -If you would like to run a script or command automatically at startup, you can specify the command using the `-s` option. The argument to this option will be parsed as a shell command (using `sh -c`) and can serve a similar function to `.xinitrc`. Unlike `.xinitrc`, the display server will not shut down when this process terminates. Instead, as dwl is shutting down, it will send this process a SIGTERM and wait for it to terminate (if it hasn't already). This makes it ideal for execing into a user service manager like [s6](https://skarnet.org/software/s6/), [anopa](https://jjacky.com/anopa/), [runit](http://smarden.org/runit/faq.html#userservices), or [`systemd --user`](https://wiki.archlinux.org/title/Systemd/User). +If you would like to run a script or command automatically at startup, you can specify the command using the `-s` option.

If you need to set environment variables that affect the entire dwl session, these must be set prior to running dwl. For example, Wayland requires a valid `XDG_RUNTIME_DIR`, which is usually set up by a session manager such as `elogind` or `systemd-logind`.
