The full syntax is <tt>sudo nano -B Path_file_name</tt> where the '''-B''' means it will create a backup of how the file was before (this can be enabled while in the editor by pressing the control key down and typing B). Alternatively use '''-C''' which stores each version in a back-up directory. If you want to edit from a particular line and column you can use '''+line.column''', and also optionally use '''-l''' (lower-case "L") to display line numbers which might be useful when trying to correct a problem with a log file like [[dayfile.txt]]. If you don't specify a file name, then nano will create a new file and you will need to specify where to save it before exit. | The full syntax is <tt>sudo nano -B Path_file_name</tt> where the '''-B''' means it will create a backup of how the file was before (this can be enabled while in the editor by pressing the control key down and typing B).

You will probably find it useful to type <tt>sudo nano /etc/nanorc</tt> as this puts you into the configuration file for nano where you can set back-up, line-numbering, and other options | |||
After typing the nano command you need to specify a filename (it might include a path, see earlier sub-section for use of '''/''' and '''~''') and there are examples later in this article, but if you decide to ''host a web site on your Pi'' then you might want to edit its home page with (.html or .php) name like <tt>sudo nano /var/www/html/index.php</tt>. After you have made an alteration to the current contents of the file, various options are shown at the bottom.
