2. open command can let you open file and url in terminal

   open . # will open the current folder in finder
   open ./XXX.md # will open the markdown file with the default editor
   open http://www.baidu.com
   open -a dash # open a application of dash
   oepn *.png # open all the png images

   killall Finder

6. Configure bash and/or vim to execute source ~/.bashrc everytime I finish editing it

   The direct way to do it:

   vim ~/.bashrc && source $_
   

   You can make an alias:

   alias vimbashrc='vim ~/.bashrc && source $_'
   

   This works in bash or zsh. In other shell, you must explicit name .bashrc to source to make it work:

   alias vimbashrc='vim ~/.bashrc && source ~/.bashrc'
