How to obtain the number of CPUs/cores in Linux from the command line?

Question

I have this script, but I do not know how to get the last element in the printout: cat /proc/cpuinfo | awk '/^processor/{print $3}' The last element should be the number of CPUs, minus 1.

Answer 1

You can use tail to read the last line

cat /proc/cpuinfo | awk '/^processor/{print $3}' | tail -1
