[ILUG-Cochin.org] File extensions

[Syam Kumar R.]

I don't think Linux judges file type from extensions. Applications and
Desktop environment recognises files in different ways. For example, Apache
recognises mime-type from file extension. But in Gnome, it is by file
content. You can rename a .txt file to .png or .jpg. It is still considered
a text file. Similarly, you can rename a png or jpg as a .txt file, it still
opens in your default image viewer. Just right click and open property
window, you can see that mime-type is listed correctly. The icon graphic
doesn't change either. If you create a .txt file or extensionless file with
some html or php code, it will open in your browser. Just adding
#!/usr/bin/sh in the beginning of a text file will make its icon change to a
shell script icon.
