Linux上運行

Question

在python2.7二進制文件我用POPEN傳遞多個變量在python運行外部程序有問題：

#!/usr/bin/env python 
import sys 
import os 
import shlex, subprocess 

a = raw_input("Enter a number:") 
b = raw_input("Enter a file:") 
c = raw_input("Enter dir to search:") 

subprocess.Popen(['/bin/sh', "./catnum.bin", "-m", a, "--remove", "-o results.txt", b, c]) 

Answer 1

你可以使用電話來代替：

from subprocess import call 
call(["cactnum.bin", "-m",a, "--remove", "-o results.txt", b, c]) 

但是每JF塞巴斯蒂安

的評論真正的問題是invalid/unnecessary /bin/sh call b) "-o results.txt"應該寫成"-o", "results.txt"（2參數）即正確的調用是：subprocess.check_call(["./catnum.bin", "-m", a, "--remove", "-o", "results.txt", b, c]) if catnum.bin is executable
