使用bash-it重新规划bash配置

直接运行 bash-it 就能看到 bash-it 的使用方法了:

lujun9972:~/ $ bash-it
bash-it             Bash-it help and maintenance
parameters:
                    1: verb [one of: help | show | enable | disable | migrate | update | search | version | reload ]
                    2: component type [one of: alias(es) | completion(s) | plugin(s) ] or search term(s)
                    3: specific component [optional]
examples:
                    $ bash-it show plugins
                    $ bash-it help aliases
                    $ bash-it enable plugin git [tmux]...
                    $ bash-it disable alias hg [tmux]...
                    $ bash-it migrate
                    $ bash-it update
                    $ bash-it search [-|@]term1 [-|@]term2 ... [ -e/--enable ] [ -d/--disable ] [ -r/--refresh ] [ -c/--no-color ]
                    $ bash-it version
                    $ bash-it reload

从中我们可以看出 bash-it 的使用很直观，都是遵循着 bash-it 行动 组件类型 [具体组件] 的格式来设计的.

bash-it自带了大量的别名、补全和插件可供直接使用，这些脚本分别存放在 $BASH_IT/aliases/available, $BASH_IT/completion/available, $BASH_IT/plugins/available 目录中. 但是你没有必要直接跑到对应目录下查看有哪些脚本， bash-it 提供了 show 行动来帮你，比如你想查看 bash-it 自带的别名、补全脚本和插件，那么可以执行下面命令:

bash-it show alisas
bash-it show completions
bash-it show plugins

lujun9972:~/ $ bash-it show aliases 
Alias               Enabled?  Description
ag                    [ ]     the silver searcher (ag) aliases
ansible               [ ]     ansible abbreviations
apt                   [ ]     Apt and dpkg aliases for Ubuntu and Debian distros.
atom                  [ ]     Atom.io editor abbreviations
bolt                  [ ]     puppet bolt aliases
......
yarn                  [ ]     yarn package manager aliases

to enable an alias, do:
$ bash-it enable alias  <alias name> [alias name]... -or- $ bash-it enable alias all

to disable an alias, do:
$ bash-it disable alias <alias name> [alias name]... -or- $ bash-it disable alias all

lujun9972:~/ $ bash-it show completions 
Completion          Enabled?  Description
apm                   [ ]     
awless                [ ]     
awscli                [ ]     
bash-it               [x]     
.....
wpscan                [ ]     

to enable a completion, do:
$ bash-it enable completion  <completion name> [completion name]... -or- $ bash-it enable completion all

to disable a completion, do:
$ bash-it disable completion <completion name> [completion name]... -or- $ bash-it disable completion all

lujun9972:~/ $ bash-it show plugins 
Plugin              Enabled?  Description
alias-completion      [x]     Automatic completion of aliases
autojump              [ ]     Autojump configuration, see https://github.com/wting/autojump for more details
......
z                     [ ]     maintains a jump-list of the directories you actually use
                              z is DEPRECATED, use fasd instead

to enable a plugin, do:
$ bash-it enable plugin  <plugin name> [plugin name]... -or- $ bash-it enable plugin all

to disable a plugin, do:
$ bash-it disable plugin <plugin name> [plugin name]... -or- $ bash-it disable plugin all

你可以很清晰地看到bash-it上有哪些组件，哪些组件已经被启用，每个组件的说明描述，以及启用/禁止组件的方法。

bash-it enable 组件类型 组件列表...
bash-it disable 组件类型 组件列表...

启用/禁止新组件后，还需要让bash-it重新加载配置才行，运行下面命令:

bash-it reload

你还可以使用 help 行为来查看组件的详细信息，比如我想了解 ansible 这个alias中定义了哪些别名，可以运行

bash-it help alias ansible

lujun9972:~/ $   bash-it help alias ansible
ans=ansible'
ap=ansible-playbook'
