find /usr/share/nano/ -iname "*.nanorc" -exec echo include {} ; >> ~/.nanorc
The -iname flag tells it to only look for files with a name that ends with .nanorc.
The -exec flags defines a command to execute on each file found.
The {} gets replaced with the file name.
; is used to signify the end of the command to execute to the find command.
Lastly, >> ~/.nanorc causes the output to be appended to your ~/.nanorc file.
