To determine the number of CPUs on a Linux system using the command line, you can use the nproc command.
To display the number of CPUs on the system, you can simply run the nproc command without any options:
nproc
This will output the number of CPUs on the system.
You can also use the grep command to retrieve the number of CPUs from the /proc/cpuinfo file. To do this, you can run the following command:
grep -c ^processor /proc/cpuinfo
This will count the number of lines in the /proc/cpuinfo file that begin with the string processor, which represents the number of CPUs on the system.
You can also use the lscpu command to display detailed information about the CPUs on the system, including the number of CPUs, the CPU architecture, and the CPU model. To use the lscpu command, you can run the following command:
lscpu
