Read data in /proc/ folder

t0msk

Hello,

I would like to get CPU model name and number of cores in Linux system. This informations are in /proc/cpuinfo file, for imagination cpuinfo folder looks like:

processor	: 0 
vendor_id	: GenuineIntel 
cpu family	: 15 
model		: 2 
model name	: Intel(R) Xeon(TM) CPU 2.40GHz 
stepping	: 7 cpu 
MHz		: 2392.371 
cache size	: 512 KB 
physical id	: 0 
siblings	: 2 
cpu cores       : 4
runqueue	: 0 
fdiv_bug	: no 
hlt_bug		: no 
f00f_bug	: no 
coma_bug	: no 
fpu		: yes 
fpu_exception	: yes 
cpuid level	: 2 
wp		: yes 
flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca  cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm 
bogomips	: 4771.02

So I want to get "model name" and "cpu cores". My idea is to read that file line by line and if line contains "model name" then I split that line by ":" and result is second string, same approach for "cpu cores". Is this approach good? Should I use contains or rather Regexp?

Thank you

Hi,

The search being not really complex, using contains should be just fine. Then you can split the line on the colon to get the value you are looking for.

ok, thank you :)

You can also use startsWith since you are looking at the start of the line content.
