"root" is a elevated privileged account that can do anything to any file at any time.

... except execute it. In order to be recognized as executable, a file needs to have at least one of the "execute" permission bits set. That's because most files simply don't contain anything that is executable, and accidentally trying to execute one of them could have bizarre or unfortunate results.

ganesh99999 you are aware that redhat dose NOT support 6.1 any longer .It is MISSING a few YEARS!!!! of security updates .

upgrade to the current older 6 ASAP
RHEL 6.7

normally one dose NOT login as root , but as a normal NON root user

for making system changes become root from your normal user account using " su - "

this is one of the reasons that linux servers tend to be more secure than Microsoft ones
