Sorry to all Technical person for mistake of Question.
Now i am post currect question
Why copied file permission is changed in destination. When i
give all permission i.e 777 to file and copy that to other
location in destination the permission is 755. But if give
permission 555 in destination that file permission is 555
and if give permission 444 to file after copy in destination
the file permission is 444. These all are happening in
normal user. How the umask value is calculate here really i
am not understand. Please write the proper answer. Thanks
Suppose you have a scheduling chain where the process 1 is
a predecessor of the process 2 and both of them are
scheduled every Monday at 8.00pm. Will I find execution log
of process 1 every Tuesday morning? And what about the
other one? Why?
