Why the umask permission of sar file is wrong if HISTORY is set greater that 28?

Solution Verified - Updated -


  • Set HISTORY greater than 28 in /etc/sysconfig/sysstat, the command /usr/lib64/sa/sa1 does not execute the command "umask 0022" until after the new output file is created, allowing it to have the wrong permissions if the root umask is not set 0022.
