Skip Password Prompts for Sudo commands

When administrating a development machine or server you may find yourself needlessly entering sudo password. On a production machine this is something you’d want but for a local or develpment machine not so much. 

 Here’s how you can bypass the password: 

 Open the  /etc/sudoers  file (as  root , of course!) by running: 

 sudo visudo 

 Note you should  never  edit  /etc/sudoers  with a regular text editor, such as  Vim  or  nano , because they do not validate the syntax like the  visudo  editor. 

 At the  end  of the  /etc/sudoers  file add this line replacing username with your actual username: 

 username ALL=(ALL) NOPASSWD:ALL 

 Save the file and exit with  <ESC>wq . If you have any sort of syntax problem,  visudo  will warn you and you can abort the change or open the file for editing again.It is important to add this line at the  end  of the file, so that the other permissions do not override this directive, since they are processed in order. 

   

 Note that for mac the save steps are a little different because mac uses vim for visudo edits.  Press the Escape key. Then, type  :wq  and press enter. This saves the file and quits vim. 

 Finally, open a new terminal window and run a command that requires  root  privileges, such as  sudo apt-get update . You should not be prompted for your password!
