  • It's a great answer, however, instead of all the information (-a option switch used in Web-E's answer) you can just get the specific numbers. This is much less confusing for a beginner - For this reason I prefer MrVaykadji and Hadi improvements.

Kernel version is:

uname -r

Ubuntu release version is:

lsb_release -r

All partition size of the HDD in Terminal

df -ht ext4

replace ext4 with your FS type if it's not so

With respect to the marked as answer post:
