To display information about the CPUs on a Linux system, you can use the "lscpu" command. This command will display a variety of information about the CPUs, including the number of CPUs, the CPU architecture, the CPU speed, and the number of cores and threads per CPU.
For example, to display the number of CPUs and their speeds, you can use the following command:
lscpu | grep "CPU(s):" -A1 | grep "Model name:"
This will display output like this:
CPU(s): 2 Model name: Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz
This shows that the system has 2 CPUs, and each CPU has a model name of "Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz". The speed of the CPUs is shown as "2.30GHz".
You can also use other commands to display information about the CPUs, such as "cat /proc/cpuinfo" or "grep -m1 'cpu MHz' /proc/cpuinfo".
