豆粑粑 macos sed -i not work

MacOS 用的是BSD的sed.Ubuntu 用的GNU的sed.
习惯了gnu的，BSD的总有些小问题。
于是，根据下面的帖子在MacOS上安装 gnu-sed

1. $ which sed              
   
2. /usr/bin/sed
   
3. 
   
4. $ brew install gnu-sed
   
5. 
   
6. 
   
7. $ brew info gnu-sed
   
8. ...
   
9. GNU "sed" has been installed as "gsed".
   
10. If you need to use it as "sed", you can add a "gnubin" directory
    
11. to your PATH from your bashrc like:
    
12. PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
    
13. ...
    
14. 
    
15. $ export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
    
16. 
    
17. $ which sed                                                         
    
18. /usr/local/opt/gnu-sed/libexec/gnubin/sed

复制代码

需要注意的是，在MacOS下，不是
vi ~/.bashrc
而是
vi ~/.bash_profile
编辑后
source ~/.bash_profile
