Hi all,
I write a small script
status = os.popen('top').readlines()
print status
It calls the command line top and will print out the status.
But I have to press the keyboard q to quit top, then the status
will be printed, otherwise it just stands by with blank.
Question is. Do you know how to give q into my python script so that
top is automatically quit immediately or maybe after 1s (for
gathering information)
Why not run the actual 'top' command in batch mode with only one
iteration? It's in the man page. I'm referring to this:
status = os.popen('top -b -n 1').readlines()
Also, the following approach seems to display a nicer output:
-
#!/usr/bin/env python
import os
status=os.popen('top -b -n 1')
for i in status.readlines():
print i
-
Or how about the following?
-
#!/usr/bin/env python
import commands
status=commands.getoutput('top -b -n 1')
print status
-
Mind you, I'm just suggesting different approaches. I'm new to Python
and don't necessarily know what I'm doing. Other more experienced
people may be able to suggest something better.
