NAME
twistd - run Twisted applications (TACs, TAPs)
SYNOPSIS
twistd [options]
DESCRIPTION
Read a twisted.application.service.Application out of a file and run
it.
OPTIONS
-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.
--savestats
Save the Stats object rather than the text output of the pro-
filer.
-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.
--originalname
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 --sys-
log.
--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 direc-
tory.
-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 dae-
mons, no change otherwise).
-r, --reactor <reactor>
Choose which reactor to use. See --help-reactors for a list of
possibilities.
--help-reactors
List the names of possibly available reactors.
--spew Write an extremely verbose log of everything that happens. Use-
ful 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.
--syslog
Log to syslog instead of a file.
--version
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 modules.
SIGNALS
A running twistd accepts SIGINT for a clean shutdown and SIGUSR1 to ro-
tate log files.
