如果在运行“control userpasswords2”命令时出现“bash: control: command not found”的错误提示,则说明该命令在Linux或MacOS系统上不可用。该命令只能在Windows系统上使用。
如果您在Linux或MacOS上需要更改管理员账户的密码,可以尝试使用其他方法,例如使用chpasswd命令。具体步骤如下:
1. 打开终端并以root权限登录。
2. 输入以下命令并按Enter键:
```
sudo chpasswd username
```
其中,username为需要更改密码的用户账户。
3. 接下来,您需要输入新密码并确认密码。
4. 更改成功后,您可以退出root权限并使用新密码登录该用户账户。
请注意,使用chpasswd命令更改密码时,请务必输入正确的命令和参数,以避免造成不必要的麻烦。

-bash: service: command not found
The error message "-bash: service: command not found" means that the "service" command is not recognized by the shell. This command is used to control system services on Unix-based systems.
There are a few possible reasons why this command may not be working or recognized:
1. The service command may not be installed on your system.
2. The PATH environment variable may not be set correctly.
3. Your user account may not have sufficient permissions to run the service command.
To fix this error, you can try the following solutions:
1. Install the service command: Depending on your operating system, you may need to install a package that includes the service command. For example, on Ubuntu, you can run "sudo apt-get install sysvinit-utils" to install the package that includes the service command.
2. Set the PATH environment variable: The service command may not be in your PATH environment variable. You can check your PATH by running "echo $PATH". If the service command is not listed, you can add it to your PATH by running "export PATH=$PATH:/sbin:/usr/sbin".
3. Use sudo: If you are not running the command as a privileged user, you may need to use the sudo command to run the service command with elevated permissions. For example, "sudo service apache2 restart".
Mac bash:command not found: adb
在Mac上出现"bash: command not found: adb"的错误是因为没有配置Android环境变量。你可以按照以下步骤来配置Android环境变量:
1. 打开终端(Terminal)应用程序。
2. 输入以下命令来编辑你的bash配置文件(如果你使用的是zsh,请将".bash_profile"替换为".zshrc"):
```shell
nano ~/.bash_profile
```
3. 在打开的文件中,添加以下两行代码:
```shell
export ANDROID_HOME=/Users/$USER/Library/Android/sdk
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
```
4. 按下"Control + X"键,然后按下"Y"键保存文件,最后按下"Enter"键退出编辑器。
5. 输入以下命令来使配置文件生效:
```shell
source ~/.bash_profile
```
6. 现在,你应该能够在终端中使用adb命令了。
