The Linux Kernel 3.18.6 is now available for the users, announced Linus Torvalds. This Linux Kernel version comes with plenty of fixes and improvements. The following BASH script, when executed, despite of the system architecture (valid only for i386, i686 and x86_64 based systems), installs Linux kernel 3.18.6 in your Linux systems.
NOTE: Above script worked perfectly on my i386 system. I need confirmation from i686 and x86_64 users, if it works fine for them. Please suggest any changes to be incorporated.
