Question

What will happen when create a hard link and delete the text file?

Answer 1

Explanation:

In Unix all normal files are Hardlinks. Hardlinks in a Unix (and most (all?)) filesystems are references to what's called an inode. The inode has a reference counter, when you have one "link" to the file (which is the normal modus operandi) the counter is 1. When you create a second, third, fourth, etc link, the counter is incremented (increased) each time by one. When you delete (rm) a link the counter is decremented (reduced) by one. If the link counter reaches 0 the filesystem removes the inode and marks the space as available for use.

In short, as long as you do not delete the last link the file will remain.
