How to hide folders or files
In linux you can see the hidden files by using the command
Which list all the files inside a folder.
We can hide all the files by naming the file with a dot(.) infront of the file name
now if you list the file by using ls -l or ls command you will not be able to see the file.
The hidden folders can also be created in the same manner
eg:: mkdir .dirname
mkdir is the make directory command and .dirname is your folder name.
