Ubuntu version how to

Ubuntu version

1. lsb_release -a ▸ exact release name, version etc.
2. cat /etc/issue ▸ formal release name
3. cat /etc/issue.net ▸ cleaner version of previous one
4. cat /etc/debian_version ▸ will give you the Debian code name
5. cat /proc/version ▸ will give you quite a lot of info about your kernel, when was it compiled, which gcc version has been used etc.
6. uname -a ▸ will tell you about your kernel info, plus arch (i386 ▸ 32 bit, x86_64 ▸ 64 bit)

If you like GUI more than command line, the System page on "System Monitor" gnome-system-monitor application should give you more than enough info. Release name, architecture variant, cores in the system, RAM available, and the space available on the root file system.
