在Linux中，命令行补全是一种非常方便的功能，它可以帮助我们快速输入命令，而不需要记住每个命令的完整名称，本文将介绍如何在Linux中使用命令行补全，包括安装和配置补全工具、使用补全命令以及自定义补全规则等。

1. 安装和配置补全工具

在Linux系统中，常用的命令行补全工具有Bash、Zsh等，这里以Bash为例进行介绍，首先需要安装Bash,然后编辑~/.bashrc文件，添加以下内容：

if [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
fi

保存文件后，执行以下命令使配置生效：

source ~/.bashrc

2. 使用补全命令

在命令行中输入一个前缀，然后按下Tab键，就可以查看所有与该前缀匹配的命令，输入git并按下Tab键，可以看到如下输出：

git add        git commit         git diff            git status      git stash       git tag        git branch       git checkout       git merge       git reset         git clone       git pull
