Some interesting facts about Linux

Well, if you are a Linux user, you must be familiar with these points. These interesting facts about Linux may seem obvious to you but for beginner these must be known. 

• All files are case sensitive. In Linux unlike windows, all files are case sensitive. File, FILE, FiLe or file are completely different things in Linux. 
• etc/folder and etc/Folder are different too. Don't get messed with these case sensitive things. 

• Everything is a file. In Linux, everything is a file. A directory is a special kind of file which stores more files, but its still a file. Anything from a terminal windows to a hard disk partition, everything in Linux is represented as a file in file system. 

• file types. The file utility determines the file type. Linux doesn't care about the extension to determine the file types. The editor will treat a file of either a .doc or .txt extension as same and don't even care about it. As a system administrator, you can use the file command to determine the file type. 
• file pic33.png
• pic33.png: PNG image data, 3840 x 1200, 8-bit/color RGBA, non-interlaced
• file /etc/pass
• /etc/pass: ASCII text
