Why is the system call to delete a file called unlink () instead of delete ()?
What will be an ideal response?
The name unlink is based on what the operation is doing. When you delete a file from a directory,
Linux doesn’t actually delete the data, it merely removes the link in the specified directory that
points to the data blocks that make up the data in the file. Linux keeps a link count for each file to
show how many different links point to a file’s data blocks. When the number of these links drops
to zero (i.e. there are no directory entries that point to data), then the data blocks are released for
reuse (i.e. the data is deleted).
