搞定mac的bashrc

1、根据这篇文章：
http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html

简单的说就是：
.bash_profile is executed for login shells, while .bashrc is executed for interactive non-login shells.

Mac OS X — an exception

An exception to the terminal window guidelines is Mac OS X’s Terminal.app, which runs a login shell by default for each new terminal window, calling .bash_profile instead of .bashrc. Other GUI terminal emulators may do the same, but most tend not to.

而糟糕的是，MAC是一个例外，它会执行bash_profile，但不会去管.bashrc

===============================
2、好了，解决方案是

编辑一下.bash_profile:

if [ -f ~/.bashrc ]; then
   source ~/.bashrc
fi
===============================

3、加上最需要的两个命令
alias ll='ls -lG'
alias ls='ls -G'
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

export PATH="/usr/local/share/npm/bin:$PATH"
export NODE_PATH=/usr/local/share/npm/lib/node_modules
export PYTHONPATH=/usr/local/lib/python3.3/site-packages

一个是ll，因为用习惯了centos所以ll很好用，ls也加上color。剩下的是两个PATH

===============================

4、总得来说就是，你需要在bash_profile里写入
CLICOLOR=1
LSCOLORS=gxfxcxdxbxegedabagacad
export PS1='[33[01;32m]u@h[33[00m]:[33[01;36m]w[33[00m]$ '
#enables colorfor iTerm
export TERM=xterm-color

if [ -f ~/.bashrc ]; then
   source ~/.bashrc
fi

-----------------------------
然后在bashrc里写入

alias ll='ls -lG'
alias ls='ls -G'
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
