aliasの簡潔な設定方法

目的

毎回alias追加しようとしたときに忘れるので、簡潔に備忘録としてまとめて書く。
個人的にはclipy使うより2文字ぐらいのaliasでパパッと書くほうが早い気がするのでaliasはよく使ってます。

設定の流れ

1 . vi ~/.bashrcで下記のようにエイリアスを設定して、保存する。

# alias <設定したいalias>='<元のコマンド>'
alias dc='docker-compose'
alias ch='git checkout'
alias br='git branch'

2 . vi ~/.bash_profile実行後、下記のように設定を追加し、保存する。

# .bash_profile はターミナル起動時に読み込まれるファイルなので、 .bashrc をここから読み込むように設定しておく
source ~/.bashrc

3. source ~/.bash_profile実行で.bashrcの編集内容を読み込む。

terminalを再起動してもOK

alias追加時は1, 3のみでOK

以上。
