Often we end up “google”-ing the┬ámost silliest commands. Because its tough and rather impossible/unimportant to keep track of all weird commands.

Trust me today I ended up being silly and here is one time solution I thought of and picked commonly used commands that correspond to both DOS as well as UNIX/BASH users.

I picked some really good list from one of the site and hope this will be helpful to you all.

Please bookmark and forget to google every time.
