Symlinks in Mac ! Symbolic Links ..yeah, I know, it’s the same!

So, you are struggling with your boring Vi editor? or that default app that your mac provides for a functionality? Kill me if you are the guy with that beard who loves Linux n Vi, but this tutorial is meant for the rest of the world’s population. 

Simple Steps Ahead : 

  • ln -s  /usr/local/bin/
  • open ~/.bash_profile (if it exists, else touch ~/.bash_profile before this step)

  • source ~/.bash_profile to refresh the file bash_profile
  • type the app’s desired short name that you added in the first step.

The application should open!
