doupdates.sh is an easy to deploy BASH script shell for RPM-based Linux derives.

There are two important points to be considered:

1. With Linux realm, performing other jobs on the system while installing updates is a bless.
2. If you were Windows evangelist, Seriousley! Ther are times when rebooting after installation updates is a good idea. Linux does not do that for you automatically, thanks to god!

• Performing updates specially for couple servers requires you to babysitting them while waiting to enter next command when the previous one complete without chaos
• This would take a great deal of your time to moniter each computer as it went through update procedures.

1. A Linux RPM based systems.
2. Superuser privileges to run the script
3. Turn on the execution bit of the file as shown:

   [user@host]$ su -
    Password:
   [root@host]# chmod 700 doupdates.sh
   

4. A smile on your face :)

• Determine whether any updates are available.
• Determine whether a package that requires a reboot is being updated such as:
  • kernel
  • glibc
  • systemd
• Install those updates.
• If reboot is required, update man pages before hand; if this is not done, new and replacement man pages won't be accessible and old ones that have been removed will appear to be there even though they are not.
• Rebuild the GRUB bootloader configuration files so that it includes recovery options for each installed kernel.
• Finally do the reboot if it should.
