Question

Been following instructions for editing sudoers file  made changes but the instructions say to exit using ctrl x - this just gives me a capital X and a caret  Have tried ctrl x ctrl Q Esc   Not using nano or any other gui  just putty terminal   the change I am trying to save is to set nano as default editor   I just need to know which keys do I press and in which order   Also as a side question are there any  good  linux tutorial sites  I seem to trawl for hours trying to find the simplest answers   Good  as in explained well and without omitting vital info  like which gui you are using

The tutorial you saw was telling you how to exit nano editor. By typing Ctrl+X nano exits and if your file needs change you will be prompted to save the changes in which case to save you should press Y and then enter to save changes in the same file you open.

If you are not using any gui and you just want to leave the shell the command is Ctrl+D.

Regarding tutorial, The Linux Documentation Project would be a good place to start. If you like books I would recommend by far any book you want from O'Reilly. They have nice cd bookshelfs with good compilation for any linux sysadmin, and without much effort you can find many places where those html bookshelfs are available to read online.

To make changes to sudo from putty bash    Type visudo and press enter  Navigate to the place you wish to edit using the up and down arrow keys  Press insert to go into editing mode  Make your changes - for example  user    ALL  ALL  ALL  Note - it matters whether you use tabs or spaces when making changes  Once your changes are done press esc to exit editing mode  Now type  wq to save and press enter  You should now be back at bash  Now you can press ctrl   D to exit the session if you wish

Be careful to type exactly   wq as Wouter Verleur said at step 7  After type enter  you will save the changes and exit the visudo editor to bash
