I heard that that was possible also, but none of my systems gives
this. I should change it. I was also thinking about posix systems, but
the Linux ps does more as others, so I did not do that.
I amended the code to work with linux and linux2:
========================================================================
accepted_params = {
'pcpu',
'rss',
'size',
'time',
'vsize',
}
accepted_platforms = {
'linux',
'linux2',
}
current_platform = sys.platform
max_line_length = 200
no_of_lines = 8 # One extra for the heading
is_good_platform = False
for platform in accepted_platforms:
if platform == current_platform:
is_good_platform = True
break
if not is_good_platform:
raise Exception('Got an incompatiple platform: {0}'.
format(current_platform))
========================================================================
