TWISTD(1)                                                                                          TWISTD(1)



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 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.

       --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 --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 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. 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.

       --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 rotate log files.
