uname information.

[Kaushal Shriyan]

Hi,

I have the following information on my laptop.

kaushal at kaushal-laptop:~$ uname -v
#39-Ubuntu SMP Thu Jul 19 19:39:19 UTC 2012 -> what does this line mean?
kaushal at kaushal-laptop:~$ uname -r
3.0.0-23-generic-pae
kaushal at kaushal-laptop:~$ uname -m
i686
kaushal at kaushal-laptop:~$ uname -p
i686
kaushal at kaushal-laptop:~$ uname -i
i386
kaushal at kaushal-laptop:~$ uname -s
Linux
kaushal at kaushal-laptop:~$ uname -o
GNU/Linux
kaushal at kaushal-laptop:~$ uname -a
Linux kaushal-laptop 3.0.0-23-generic-pae #39-Ubuntu SMP Thu Jul 19
19:39:19 UTC 2012 i686 i686 i386 GNU/Linux
kaushal at kaushal-laptop:~$

Also not sure what is the difference between -p or -i or -m flags to
uname. Can someone please help me understand?
what is the basic difference between i386,i486 ,i586,i686?

Regards,

Kaushal
