# A small utility to wrap up a PyWBEM session in a Python interactive
23
# console.
24
#
25
# Usage:
26
#
27
# wbemcli.py HOSTNAME [-u USERNAME -p PASSWORD] [-n namespace] [--no-ssl] \
28
# [--port PORT]
29
#
30
# CIM operations can be executed by using the PyWBEM connection object
31
# called 'cli' in the global scope. There are two sets of aliases
32
# available for usage in the interpreter. For example the following
33
# three commands are equivalent:
34
#
35
# >>> cli.EnumerateInstanceNames('SMX_ComputerSystem')
36
# >>> EnumerateInstanceNames('SMX_ComputerSystem')
37
# >>> ein('SMX_ComputerSystem')
38
#
39
# Pretty-printing of results is also available using the 'pp'
40
# function. For example:
41
#
42
# >>> cs = ei('SMX_ComputerSystem')[0]
43
# >>> pp(cs.items())
44
# [(u'RequestedState', 12L),
45
# (u'Dedicated', [1L]),
46
# (u'StatusDescriptions', [u'System is Functional']),
47
# (u'IdentifyingNumber', u'6F880AA1-F4F5-11D5-8C45-C0116FBAE02A'),
