I think you are getting confused. "touch" does not change inode number,
it changes inode data essentially modification and access time date
stamps by default. vi (like some editors and some other utilities),
makes a copy of the current file and then removes the file when the
user saves the file, the copy is "re-saved" to the original position and
hence the inode is changed. If you want to cross check, make a hard link
to the file and then edit the file using vi and you will find the inode
will not be changed.

No.I know 'touch' shouldn't change the inode value.Thats what the whole
issue is.I do a 'touch' on a particular file and then if I use 'stat' I see
a different inode value.
