Public bug reported:
*** SORRY FOR MY BAD ENGLISH ***
*** I was doing my daily exercise on the topic of timestamps.
--> How the timestamps of the particular file gets changed, when
we do some changes in that particular file.
1)--> ex:- cat
Access time is changed.
2)--> ex:- vi
If some modification is made in that particular file with
the help of vi editor.
then how the access,modification,change time of the
particular gets changed.
3)--> ex:- chmod
If we do chmod to a particular file only the change time of
that file gets changed.
4)-->ex:- touch
If we touch a file, then all the timestamp get changed.
*** I was using stat tool to check all the timestamps ***
*************************************************************************************************
HERE IS THE PROBLEM WHICH I AM FACING EVERYTIME,WHEN I DO STAT TO THAT
PARTICULAR FILE.
*************************************************************************************************
--> The inode number of that file gets changed, as I do any modification to
that file.

*************************************************************************************************
-> When I touched file named test & did stat on that file, the inode number was
56640.
-> But as I edit the same file and add something to it, its inode number
changed again to 56643.
-> Inode number should not change. then how come it gets changed !!!
