In this post, I will cover the cli commands that can be used to get system information. I will also cover some GUI tools in my upcoming posts. Embedded systems do not have GUI capabilities & hence the following commands would be handy despite the availability of various GUI based tools.
CPU Info
How many processors does the system have?
Method1:
root@babu-VirtualBox:~# grep processor /proc/cpuinfo
processor : 0
processor : 1
root@babu-VirtualBox:~#
root@babu-VirtualBox:~# lscpu | grep "CPU(s):"
CPU(s): 2
root@babu-VirtualBox:~#
What processor make/vendor, speed?
Method1:
root@babu-VirtualBox:~# grep "model name" /proc/cpuinfo | unique <-- architecture specific, but works for intel processors
model name : Intel(R) Core(TM) i7-3540M CPU @ 3.00GHz
root@babu-VirtualBox:~#
Method2:
root@babu-VirtualBox:~# lscpu | grep Vendor
Vendor ID: GenuineIntel
root@babu-VirtualBox:~#
root@babu-VirtualBox:~# lscpu | grep MHz
CPU MHz: 2976.472
root@babu-VirtualBox:~#
What is processor type/architecture?
Method1:
root@babu-VirtualBox:~# uname -p
i686
root@babu-VirtualBox:~#
root@babu-VirtualBox:~# uname -m
i686
root@babu-VirtualBox:~#
Method2:
root@babu-VirtualBox:~# arch <-- is this installed kernel or processor type?
i686
root@babu-VirtualBox:~#
Method3:
root@babu-VirtualBox:~# lscpu | grep Architecture
Architecture: i686
root@babu-VirtualBox:~#
Is the processor 32-bit or 64-bit or both? (this is different from whether the running OS is 32-bit or 64-bit)
root@babu-VirtualBox:~# lscpu | grep "CPU
op"
CPU op-mode(s):
32-bit
root@babu-VirtualBox:~#
What is the endian-ness of the processor?
root@babu-VirtualBox:~# echo -n I | od -to2 | awk 'FNR==1{ print substr($2,6,1)}'
1
root@babu-VirtualBox:~#
<-- 0 if Big endian, 1 if little endian
root@babu-VirtualBox:~# lscpu | grep
"Byte"
Byte Order:
Little Endian
root@babu-VirtualBox:~#
RAM Info
What is the RAM size?
Method1:
root@babu-VirtualBox:~# cat /proc/meminfo | grep MemTotal
MemTotal:
1026276 kB
root@babu-VirtualBox:~#
Method2:
root@babu-VirtualBox:~# free -m
total used free shared buffers cached
Mem: 1002 732 269 0 43 431
-/+ buffers/cache: 257 744
Swap: 510 110 400
root@babu-VirtualBox:~#
Disk Info
What is the size of the disk?
root@babu-VirtualBox:~#
df | grep '^/dev/*' | awk '{s+=$2} END {print s/1048576}'
54.0081 <--- in GB
root@babu-VirtualBox:~#
root@babu-VirtualBox:~#
inxi -D
Drives:
HDD Total Size: 59.6GB (23.8% used) 1: id: /dev/sda model:
VBOX_HARDDISK size: 59.6GB
root@babu-VirtualBox:~#
Is the disk SSD or HDD?
root@babu-VirtualBox:~# cat /sys/block/sda/queue/rotational
1 <--- 1 for hard disks and 0 for an SSD
root@babu-VirtualBox:~#
OS Info
What is the OS distribution?
root@babu-VirtualBox:~# head -n1 /etc/issue
Ubuntu 13.10 \n \l
root@babu-VirtualBox:~#
root@babu-VirtualBox:~# cat /etc/*-release

root@babu-VirtualBox:~#
root@babu-VirtualBox:~# cat /proc/version

root@babu-VirtualBox:~#
Is the OS 32-bit or 64-bit?
root@babu-VirtualBox:~# uname -a

root@babu-VirtualBox:~# file /sbin/init (or any binary in /bin directory)

root@babu-VirtualBox:~#
<--- 32-bit above indicates 32 bit. 64 bit above indicates 64 bit.
root@babu-VirtualBox:~# getconf LONG_BIT
32 <----- 32, if OS is 32 bit - 64, if OS is 64 bit
