You probably know that modern Linux distributions have many things in common. Well, one of the reasons for this is LSB – Linux Standard Base. LSB is a joint project by a number of Linux vendors to standardize the OS environment.
The goal of the LSB is to develop and promote a set of standards that will increase compatibility among Linux distributions and enable software applications to run on any compliant system. In addition, the LSB will help coordinate efforts to recruit software vendors to port and write products for Linux.
One of the immediate benefits of LSB compliancy is ability to confirm the exact information about your Linux release using the lsb_release command. By exact information I mean the release version, vendor name and most interestingly the codename of your current Linux release.
