我正在尝试将top -n1写入python中的文件。它给出了缓冲区大小错误。我是python的新手,对它不了解,因为它看起来很简单。
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()
错误:
p = subprocess.Popen(“ top”,“ n1”,stdout = subprocess.PIPE,shell = False)
文件 “ /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py”, 第659行, init 引发TypeError(“ bufsize必须为整数”)TypeError:bufsize必须为整数
将buffsize添加为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()
错误:
p = subprocess.Popen(“ top”,“ n1”,stdout = subprocess.PIPE,shell = False, bufsize = 1)TypeError: init ()获得了多个关键字值 参数'bufsize'
答案 0 :(得分:1)
尝试一下。
import subprocess
p = subprocess.Popen(["top", "n1", "b"], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
output, err = p.communicate()
代表批量模式的"b"
解决了top: failed tty get
错误。
