twistd - run Twisted applications (TACs, TAPs)


twistd [options]


Read a twisted.application.service.Application out of a file and run it.


-n, --nodaemon Don't daemonize (stay in foreground).

-q, --quiet
No-op for backwards compatibility.

-p, --profile <profile output>
Run the application under the profiler, dumping results to the specified file.

--profiler <profiler name>
Specify the profiler to use. Defaults to the 'hotshot' profiler.

Save the Stats object rather than the text output of the profiler.

-b, --debug
Run the application in the Python Debugger (implies --nodaemon option). Sending a
SIGINT or SIGUSR2 signal to the process will drop it into the debugger.

-e, --encrypted <file>
The specified tap/aos file is encrypted.

--euid Set only effective user-id rather than real user-id. This option has no effect
unless the server is running as root, in which case it means not to shed all
privileges after binding ports, retaining the option to regain privileges in cases
such as spawning processes. Use with caution.

-o, --no_save
Do not save shutdown state.

Behave as though the specified Application has no process name set, and run with
the standard process name (the Python binary in most cases).

-l, --logfile <logfile>
Log to a specified file, - for stdout (default: twistd.log). The log file will be
rotated on SIGUSR1.

-l, --logger <fully qualified python name>
A fully-qualified name to a log observer factory to use for the initial log
observer. Takes precedence over --logfile and --syslog.

--pidfile <pidfile>
Save pid in specified file (default: twistd.pid).

--chroot <directory>
Chroot to a supplied directory before running (default: don't chroot). Chrooting
is done before changing the current directory.

-d, --rundir <directory>
Change to a supplied directory before running (default: .).

-u, --uid <uid>
The uid to run as (default: don't change).

-g, --gid <gid>
The gid to run as (default: don't change).

--umask <mask>
The (octal) file creation mask to apply. (default: 0077 for daemons, no change

-r, --reactor <reactor>
Choose which reactor to use. See --help-reactors for a list of possibilities.

List the names of possibly available reactors.

--spew Write an extremely verbose log of everything that happens. Useful for debugging
freezes or locks in complex code.

-f, --file <tap file>
Read the given .tap file (default: twistd.tap).

-s, --source <tas file>
Load an Application from the given .tas (AOT Python source) file.

-y, --python <python file>
Use the variable "application" from the given Python file. This option overrides
-f. This option implies --no_save.

Log to syslog instead of a file.

Print version information and exit.

--prefix <prefix>
Use the specified prefix when logging to logfile. Default is "twisted".

Note that if twistd is run as root, the working directory is not searched for Python


A running twistd accepts SIGINT for a clean shutdown and SIGUSR1 to rotate log files.
