# ma-cli auto-completion自动补全命令
命令行自动补全是指用户可以在Terminal中输入命令前缀通过Tab键自动提示支持的ma-cli命令。ma-cli自动补全功能需要手动在Terminal中激活。执行**ma-cli auto-completion**命令，用户根据提示的补全命令，复制并在当前Terminal中执行，就可以自动补全ma-cli的命令。目前支持Bash、Fish及Zsh三种Shell，默认是Bash。
以Bash命令为例：在Terminal中执行**eval "$(_MA_CLI_COMPLETE=bash_source ma-cli)"** 激活自动补全功能。
```
eval "$(_MA_CLI_COMPLETE=bash_source ma-cli)"
```
此外，可以通过"ma-cli auto-completion Zsh"或"ma-cli auto-completion Fish"命令查看"Zsh"、"Fish"中的自动补全命令。
