8
10 usage: ../bin/fail2ban-python [option] ... [-c cmd | -m mod | file | -]
11 [arg] ... Options and arguments (and corresponding environment vari‐
12 ables): -B : don't write .py[co] files on import; also PYTHONDON‐
13 TWRITEBYTECODE=x -c cmd : program passed in as string (terminates
14 option list) -d : debug output from parser; also PYTHONDEBUG=x -E
15 : ignore PYTHON* environment variables (such as PYTHONPATH) -h :
16 print this help message and exit (also --help) -i : inspect inter‐
17 actively after running script; forces a prompt even
18
19 if stdin does not appear to be a terminal; also PYTHONINSPECT=x
20
21 -m mod : run library module as a script (terminates option list) -O
22 : optimize generated bytecode slightly; also PYTHONOPTIMIZE=x -OO :
23 remove doc-strings in addition to the -O optimizations -R : use a
24 pseudo-random salt to make hash() values of various types be
25
26 unpredictable between separate invocations of the interpreter,
27 as a defense against denial-of-service attacks
28
29 -Q arg : division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew -s
30 : don't add user site directory to sys.path; also PYTHONNOUSERSITE -S
31 : don't imply 'import site' on initialization -t : issue warnings
32 about inconsistent tab usage (-tt: issue errors) -u : unbuffered
33 binary stdout and stderr; also PYTHONUNBUFFERED=x
34
35 see man page for details on internal buffering relating to '-u'
36
37 -v : verbose (trace import statements); also PYTHONVERBOSE=x
38
39 can be supplied multiple times to increase verbosity
40
41 -V : print the Python version number and exit (also --version) -W
42 arg : warning control; arg is action:message:category:module:lineno
43
44 also PYTHONWARNINGS=arg
45
46 -x : skip first line of source, allowing use of non-Unix forms of
47 #!cmd -3 : warn about Python 3.x incompatibilities that 2to3 cannot
48 trivially fix file : program read from script file - : program
49 read from stdin (default; interactive mode if a tty) arg ...: arguments
50 passed to program in sys.argv[1:]
51
52 Other environment variables: PYTHONSTARTUP: file executed on interac‐
53 tive startup (no default) PYTHONPATH : ':'-separated list of directo‐
54 ries prefixed to the
55
56 default module search path.
57 The result is sys.path.
58
59 PYTHONHOME : alternate <prefix> directory (or <prefix>:<exec_pre‐
60 fix>).
61
62 The default module search path uses <prefix>/pythonX.X.
63
64 PYTHONCASEOK : ignore case in 'import' statements (Windows). PYTHO‐
65 NIOENCODING: Encoding[:errors] used for stdin/stdout/stderr. PYTHON‐
66 HASHSEED: if this variable is set to 'random', the effect is the same
67
68 as specifying the -R option: a random value is used to seed the
69 hashes of str, bytes and datetime objects. It can also be set
70 to an integer in the range [0,4294967295] to get hash values
71 with a predictable seed.
