I'm reading a file output by the system utility WMIC in windows (so I can track
CPU usage by process ID) and the text file WMIC outputs seems to have extra
characters in I've not seen before.
I use os.system('WMIC /OUTPUT:c:\cpu.txt PROCESS GET ProcessId') to output the
file and parse file c:\cpu.txt
The first few lines of the file look like this in notepad
ProcessId
0
4
568
624
648
I input the data with the lines
infile = open('c:\cpu.txt','r')
infile.readline()
infile.readline()
infile.readline()
the readline()s yield the following output
'\xff\xfeP\x00r\x00o\x00c\x00e\x00s\x00s\x00I\x00d\x00 \x00 \x00\r\x00\n'
'\x000\x00 \x00 \x00 \x00 \x00 \x00 \x00 \x00 \x00 \x00\r\x00\n'
'\x004\x00 \x00 \x00 \x00 \x00 \x00 \x00 \x00 \x00 \x00 \x00\r\x00\n'
Now for the first line the title 'ProcessId' is in this string but the
individual characters are separated by '\x00' and at least for the first line
of the file there is an extra '\xff\xfe'. For subsequent its just '\x00. Now I
can just replace the '\x**' with '' but that seems a bit inelegant. I've tried
various options on the open 'rU' and 'rb' but no effect.
Does anybody know what the rubbish characters are and what has caused the. I'm
using the latest Enthought python if that matters.
