apt-get and red hat

I am new to linux (I'm solaris) and

I have been introduced to apt-get to check and upgrade packages.

I was told there is an option or form of the command to rebuild the kernel.

apt-get install kernel

Is this the form to upgrade the kernel, or you use

apt-get upgrade kernel

thanks

The kernel is a package just like any other. You can use 'apt-get install kernel-package-name' to install a specific package, or 'apt-get upgrade' to upgrade your currently installed packages -- that should include the kernel if there are updates available.
