We have learned that you can use the following days commands to view information about the Linux kernel version and the Ubuntu release:
Uname-r
Uname-a
Cat/proc/version
Lsb-release-a
Wait a minute
You can see that the kernel version of the current ubuntu12.04.5lts is Linux 3.2.0-23-generic-pae, so what are the rules for version numbering?
What does generic and PAE mean?
First, the Linux kernel version number sequence
The kernel version number for Linux is typically:
The major version number. minor version number. Revision number
Major version: the main kernel version currently in use;
Minor version number: The minor version number is even, that is, the kernel version is stable version, the odd is the non-stable version;
Revision Number: indicates the number of revisions to the kernel version.
For example, here we have the kernel version number is 3.2.0-23-GENERIC-PAE, where the major version number is 3, the minor version number is 2, which is the stable version, the revision number is 0, and 23 is the 23rd fine-tuning patch for the current version.
Note the major and minor version numbers determine the series of cores.
