I'm trying to write top -n1 to a file in python. It is giving a buffer size error. I'm new to python, and don't understand this as it looks pretty straight forward.
import subprocess
p = subprocess.Popen("top", "n1",stdout=subprocess.PIPE, shell=False)
(output, err) = p.communicate()
topfile = open("top.txt","w+")
topFile.write(output)
topFile.close()
Error:
p = subprocess.Popen("top", "n1",stdout=subprocess.PIPE, shell=False)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 659, in init raise TypeError("bufsize must be an integer") TypeError: bufsize must be an integer
Adding in buffsize as int
import subprocess
p = subprocess.Popen("top", "n1",stdout=subprocess.PIPE, shell=False, bufsize =1)
(output, err) = p.communicate()
topHeavyFile = open("topHeavy.txt","w+")
topHeavyFile.write(output)
topHeavyFile.close()
Error:
p = subprocess.Popen("top", "n1",stdout=subprocess.PIPE, shell=False, bufsize =1) TypeError: init () got multiple values for keyword argument 'bufsize'
Try this.
import subprocess
p = subprocess.Popen(["top", "n1", "b"], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
output, err = p.communicate()
The "b"
which stands for batch mode solves the top: failed tty get
error.
