编辑 /etc/make.conf 加入 bash-completion USE 标记。
然后重新编译系统里所有支持这个 USE 标记的软件包：
$ emerge -avuN world

安装 bash-completion 和 eselect
$ emerge -av bash-completion eselect

确保 ~/.bashrc 里有下面一行:
[[ -f /etc/profile.d/bash-completion ]] && source /etc/profile.d/bash-completion

最后source一下~/.bashrc：
$ source ~/.bashrc

为了给portage相关命令(比如emerge, equery, revdep-rebuild 等) 加上 tab 补齐功能，
需要安装 gentoo-bashcomp
$ emerge gentoo-bashcomp

启用gentoo-bashcomp
$ bashcomp-config enable gentoo
$ source ~/.bashrc

列出需要手工启用bash-completion的命令列表
$ bashcomp-config list

启用rar的bash-completion
$ bashcomp-config enable unrar
$ source ~/.bashrc


Bash Completion in Gentoo

In Gentoo, bash-completion is not enabled by default, so for each package compiled with bash-completion support, we need to manually enable it for completion. Here’re the relevant steps and tools to manage bash-completion.

$ emerge bash-completion eselect

Activate bash-completion in bashrc:

[[ -f /etc/profile.d/bash-completion ]] && source /etc/profile.d/bash-completion

Add to USE flag, so packages can be compiled with bash-completion support if available:

USE="bash-completion"

Use eselect to view and manage packages availabe for bash-completion:

$ eselect bashcomp list

Enable packages for completion globally, e.g.,

$ eselect bashcomp enable --globally eix eselect genlop gentoo subversion

Bash needs to be restarted before the changes will take effect.
