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      :  issue  warnings  about
       comparing bytearray with unicode

              (-bb: issue errors)

       -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.
