我有一个 python 程序,它将 cat 一个文件,然后仅当在输出中找到单词“oranges”时才打印输出。我想知道如果在输出中找到“橙子”,我怎么能扭转这个并且让程序不输出任何东西?
#! /usr/bin/python
import commands, os, string
import sys
import fileinput
import subprocess
from subprocess import Popen, PIPE
import shlex
cmd = "cat /root/newfile.txt"
args = shlex.split(cmd)
p = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = p.communicate()
if out.find("oranges") > -1:
print out
