Linux 命令行别名非常适合帮助你提高工作效率。更好的是,在你安装的 Linux 发行版中默认就包含了一些别名。
|
||
|
||
这是 Fedora 27 中的命令别名的示例:

|
||
|
||
这个 `alias` 命令列出了已有的别名。设置别名也十分简单:
|
||
|
||
```
|
||
alias new_name="command"
|
||
```
|
||
|
||
这里有 15 个命令行别名,可以节省你的时间:
|
||
|
||

|
||
|
||
```
|
||
alias install="sudo yum install -y"
|
||
```
|
||
|
||
在这里,根据每个用户的偏好,`sudo` 和 `-y` 是可选的:
