Version of UNIX/BSD I am using - uname tutorial

To find out which version of OS we are using, we will use UNIX uname command, alone, or with additional options:

This is result on my system:

#uname
OpenBSD

More info about system you will get with "uname -a":

#uname -a OpenBSD swordfish 4.8 GENERIC#136 i386

Machine type,  "uname -m":

#uname -m i386

Machine nodename (network name),  "uname -n":

#uname -n swordfish

Some details on processor, "uname -p":

#uname -p Intel(R) Pentium(R) 4 Mobile CPU 1.70 GHz ("GenuineIntel" 686-class)

Release with "uname -r":

#uname -r 4.8

System version, "uname -v":

#uname -v GENERIC#136

All in all, except "uname -p" for info on CPU, all you need is "uname -a".

Check your man uname page.
