file modification time
<posted & mailed>
I have noticed that a user can change a file, if he belongs to
the same group, to which rw privileges have been set, but he cannot
change its date, using 'touch'.
Is that resul expected?
E.g. User vi-opened a file not owned by him, but belonging to its group,
with permissions: 100664, succesfully exiting with wq.
I have checked that modification date had changed.
As i try 'touch -m 12302007' i get: 'Operation not permitted'
What is wrong?
thank you for you seggestions
