Mac 环境变量

vim ~/.bash_profile
source ~/.bash_profile

.bash_profile 内容如下

export RUBYOPT=-KU
export PATH=$PATH:/Users/xxx/Documents/platform-tools/
export PATH=${PATH}:/usr/local/mysql/bin/:/usr/local/opt/php56/bin

alias ll='ls -l'
alias gotosh='cd ~/sh'

但 .bash_profile 只在用户登录时加载一次，新开终端时不会再次加载
借助 iterms 的 Send text as start 实现新开终端加载

后来环境变量和其它分开放
.bash_profile

export RUBYOPT=-KU
export PATH=$PATH:/Users/xxx/Documents/platform-tools/
export PATH=${PATH}:/usr/local/mysql/bin/:/usr/local/opt/php56/bin

if test -f ~/.bashrc ; then
    source ~/.bashrc
fi

.bashrc

alias ll='ls -l'
alias gotosh='cd ~/sh'
