我被教导如何通过 subprocess.call
的两种方法更改 mac 地址,而第一种方法成功但第二种方法给我错误,我无法理解
这是我的代码:
#! /usr/bin/python3.5
import subprocess
interface = input("Enter Interface of Your Choice: ")
mac_chg = input("Enter New Mac Address: ")
print("[+]Changing Mac ADDRESS of " + interface + " to " + mac_chg)
subprocess.call(["ifconfig", interface, "down"])
subprocess.call(["ifconfig", interface, "hw", "ether", mac_chg])
subprocess.call(["ifconfig", interface, "up"])
这是错误:
Traceback (most recent call last):
File "/home/kali/PycharmProjects/hello/main.py", line 7, in <module>
subprocess.call(["ifconfig", interface, "down"])
File "/usr/lib/python3.8/subprocess.py", line 340, in call
with Popen(*popenargs, **kwargs) as p:
File "/usr/lib/python3.8/subprocess.py", line 854, in __init__
self._execute_child(args, executable, preexec_fn, close_fds,
File "/usr/lib/python3.8/subprocess.py", line 1702, in _execute_child
raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'ifconfig'
Process finished with exit code 1
由于这个错误,我无法继续进行。
最佳答案
在 Linux 中,默认情况下 subprocess.call
不使用 shell 来运行我们的命令,因此您不能使用像 cd
这样的 shell 命令。
所以只需向 subprocess.call
添加一个参数即 shell=True
然后尝试执行。
例如:
subprocess.call(["ifconfig", interface, "down"], shell=True)
关于python - 找不到文件错误 : [Errno 2] No such file or directory: 'ifconfig' ,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/63805710/
