Get hardware information from /proc filesytem in Linux

Question

I use execv to run lshw command to get the CPU, disk, and memory in C code. But I would like to search another solution to get these information fr

Answer 1

1: To get the CPU load use this command :

top -bn1 | grep load

this will give you output like :

top - 12:26:20 up 35 min,  2 users,  load average: 0.02, 0.01, 0.00

now parse the load average from above string. 2: To get memory info use this command :

free -m

This will give you:

total       used       free     shared    buffers     cached
Mem:         15926        308      15617          6         15        122
-/+ buffers/cache:        171      15755
Swap:            0          0          0

To get the disk info , use this :

df -H /home/test

This will give you :

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       102G  5.4G   91G   6% /

Now from above result parse the content what you want.
