NAME

       fail2ban-python - a helper for Fail2Ban to assure that the same Python is used

DESCRIPTION

       usage:  fail2ban-python  [option]  ... [-c cmd | -m mod | file | -] [arg] ...  Options and
       arguments (and corresponding environment variables): -B     : don't write .py[co] files on
       import;  also  PYTHONDONTWRITEBYTECODE=x  -c cmd : program passed in as string (terminates
       option list) -d     : debug output from parser; also PYTHONDEBUG=x -E     : ignore PYTHON*
       environment variables (such as PYTHONPATH) -h     : print this help message and exit (also
       --help) -i     : inspect interactively after running script; forces a prompt even

              if stdin does not appear to be a terminal; also PYTHONINSPECT=x

       -m mod : run library module as  a  script  (terminates  option  list)  -O      :  optimize
       generated bytecode slightly; also PYTHONOPTIMIZE=x -OO    : remove doc-strings in addition
       to the -O optimizations -R     : use a pseudo-random salt to make hash() values of various
       types be

              unpredictable between separate invocations of the interpreter, as a defense against
              denial-of-service attacks

       -Q arg : division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew -s      :  don't  add
       user  site directory to sys.path; also PYTHONNOUSERSITE -S     : don't imply 'import site'
       on initialization -t     : issue warnings about inconsistent tab usage (-tt: issue errors)
       -u     : unbuffered binary stdout and stderr; also PYTHONUNBUFFERED=x

              see man page for details on internal buffering relating to '-u'

       -v     : verbose (trace import statements); also PYTHONVERBOSE=x

              can be supplied multiple times to increase verbosity

       -V      :  print  the  Python  version  number  and exit (also --version) -W arg : warning
       control; arg is action:message:category:module:lineno

              also PYTHONWARNINGS=arg

       -x     : skip first line of source, allowing use of non-Unix forms of #!cmd -3     :  warn
       about  Python  3.x  incompatibilities that 2to3 cannot trivially fix file   : program read
       from script file -      : program read from stdin (default; interactive mode if a tty) arg
       ...: arguments passed to program in sys.argv[1:]

       Other  environment  variables:  PYTHONSTARTUP:  file  executed  on interactive startup (no
       default) PYTHONPATH   : ':'-separated list of directories prefixed to the

       default module search path.
              The result is sys.path.

       PYTHONHOME   : alternate <prefix> directory (or <prefix>:<exec_prefix>).

              The default module search path uses <prefix>/pythonX.X.

       PYTHONCASEOK  :  ignore  case  in  'import'   statements   (Windows).    PYTHONIOENCODING:
       Encoding[:errors]  used  for stdin/stdout/stderr.  PYTHONHASHSEED: if this variable is set
       to 'random', the effect is the same

              as specifying the -R option: a random value is used to  seed  the  hashes  of  str,
              bytes  and  datetime  objects.   It  can  also  be  set  to an integer in the range
              [0,4294967295] to get hash values with a predictable seed.
