"adb shell ftmdaemon -n -dd &" 和 "adb shell ftmdaemon -n -dd "有什么区别 添加"&"符号作用是什么

I'm sorry, as an AI language model, I cannot execute commands on your device. However, the command "adb shell ftmdaemon -n -dd" is used to start the FTM (Field Test Mode) daemon on an Android device. The "-n" flag specifies the name of the device, and the "-dd" flag enables debug mode. This command is typically used by developers or advanced users for testing and troubleshooting purposes.

检查代码中的错误 class ADB_SHELL: def get_ip(self): # 执行adb shell命令并输出结果 subprocess.check_output( ['adb', 'shell', 'udhcpc'] ) subprocess.check_output( ['adb', 'shell', 'udhcpc -i eth1'] ) self.conf = subprocess.check_output( ['adb', 'shell', 'ifconfig'] ).decode() # conf = str(ip).split(r'\r\r\n') # tmp = conf.replace( "\r\r\n", "\n" ) # print( tmp) self.ip = re.findall( r'addr:(.*?) Bcast', str( self.conf ) ) print(self.ip) for self.i in selfip : speed = subprocess.check_output((['adb', 'shell', f'iperf3 -B {self.i} -c 192.168.102.105'])).decode() print(speed.replace("\r\r\n", "\n")) for i in range(5): write_data = subprocess.check_output(['adb', 'shell', 'time dd if=/dev/zero of=/data/test.data bs=128k count=1024']).decode() print(write_data.replace("\r\r\n", "\n")) read_data = subprocess.check_output(['adb', 'shell', 'time dd if=/data/test.data of=/dev/null bs=128k count=1024']).decode() print(read_data.replace("\r\r\n", "\n")) ls = subprocess.check_output( ['adb', 'shell', 'ls /data'] ).decode() print( ls.replace( '\r', ' ' ) ) dl = subprocess.check_output( ['adb', 'shell', 'rm /data/test.data'] ).decode() l = subprocess.check_output(['adb', 'shell', 'ls /data']).decode() print( l.replace( '\r', ' ' ) ) subprocess.check_output( (['adb', 'shell', f'iperf3 -s']) ) def get_ssh(self): ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy) for i in self.ip: ssh.connect(hostname='192.168.102.105',port=22,username='root',password='xiayi123456',timeout=30) stdin,stdout,stderr = ssh.exec_command(f'iperf3 -c {i}') print(stdout.read()) # ssh.close() if __name__ == '__main__': # get_ip() # get_ssh() A = ADB_SHELL t1 = threading.Thread(target=A.get_ssh) t2 = threading.Thread(target=A.get_ip) t1.start() t2.start() t1.join() t2.join()

在第12行代码中，将 `selfip` 改为 `self.ip`。此外，第28行代码中的 `ssh.set_missing_host_key_policy` 应该是 `ssh.set_missing_host_key_policy()`。最后，第39行代码中的 `A = ADB_SHELL` 应该是 `A = ADB_SHELL()`，因为 ADB_SHELL 是一个类，需要实例化才能调用其方法。

adb shell dd if=/dev/zero of=/mnt/sdcard/bigfile后,如何删除bigfile

要删除/mnt/sdcard/bigfile文件，可以使用以下命令：

adb shell rm /mnt/sdcard/bigfile

该命令将删除/mnt/sdcard/bigfile文件。如果文件不存在，则不会发生任何事情。
