Do you like to see processor model name only:

#  grep -i 'model name' /proc/cpuinfo | uniq

model name      : Intel(R) Core(TM) i3-3110M CPU @ 2.40GHz


Find number of core in processor :

#  lscpu

CPU(s):                4


(or)

# lshw -C processor


Check Operating System Version:

#  cat /etc/lsb-release



DISTRIB_ID=Ubuntu

DISTRIB_RELEASE=13.10

DISTRIB_CODENAME=saucy

DISTRIB_DESCRIPTION="Ubuntu 13.10"

(or)

# lsb_release -a


(or)

# lsb_release -r

Release:        13.10

(or)

# cat /etc/issue

Ubuntu 13.10 \n \l

(or)

cat /etc/issue.net

Ubuntu 13.10



Whether my system is 32 bit o 64 bit?
