Ubuntu - How to View or Show Hidden Files in Nautilus or Terminal - Linux
By default, Ubuntu hides hidden files and folders. If you want to view them, you can do it from the file browser Nautilus or from the command line terminal. Here is how:
File Browser Nautilus:
While you have the file browser open, just hit "Ctrl + h". That will allow you to view the hidden files and folders.
The "ls" command will only display files and directories that aren't hidden unless you supply the -a switch. "ls -a" will show you all files and directories, including hidden ones.
