lscpu -e


The lscpu command also has an -x option, which can display extended information about the CPU. This option displays a wide range of information about the CPU, including the CPU’s model name, the CPU’s microarchitecture, and the CPU’s flags. The -x option can be used as follows:

lscpu -x


In addition to the options mentioned above, the lscpu command has many other options that can be used to obtain specific pieces of information about the CPU. For a complete list of options and more detailed information about using the lscpu command, you can type man lscpu at the command prompt to view the lscpu man page.
