**NAME**
**phd** - phabricator daemon launcher
**COMMAND REFERENCE**
**start**
Start the normal collection of daemons that Phabricator uses. This
is appropriate for most installs. If you want to customize what
is launched, you can use **launch** for fine-grained control.
**restart**
Stop all running daemons, then start a standard loadout.
**stop** [PID ...]
Stop all running daemons if no PIDs are given, or a particular
PID or set of PIDs, if they are supplied.
**launch** [__n__] __daemon__ [argv ...]
**debug** __daemon__ [argv ...]
Start a daemon (or n copies of a daemon).
With **debug**, do not daemonize. Use this if you're having trouble
getting daemons working.
**list**
List available daemons.
**status**
List running daemons. This command will exit with a non-zero exit
status if any daemons are not running.
**help**
Show this help.
- **repository-launch-master**
- DEPRECATED. Use 'phd start'.
-
- **repository-launch-readonly**
- DEPRECATED. Use 'phd launch pulllocal -- --no-discovery'.
