You can use the following command to find information about the CPU on a Red Hat Linux (RHEL) system:
lscpu
This command provides a detailed report of the CPU architecture, including the number of processors, cores, and threads, clock speed, cache size, and other information.
You can also use the /proc/cpuinfo file to get information about the CPU:
cat /proc/cpuinfo
This file provides similar information as the lscpu command but may be more difficult to read and interpret.
Note that the exact output of these commands may vary depending on the specific hardware and configuration of the system.
