Hardinfo also performs a few benchmark tests taking a few minutes before the report is displayed. The report can also be written to a text file. The cpu information is towards the beginning of the report. It would produce a large report about many hardware parts, by reading files from the /proc directory. But it can also run from the command line only if there is no gui display available. Hardinfo is a gtk based gui tool that generates reports about various hardware components. It would simply print the cpu hardware details in a user-friendly format. Lscpu is a small and quick command that does not need any options. This indicates that there are 4 actual cores. To get the actual number of cores, check the core id for unique values $ cat /proc/cpuinfo | grep 'core id' For example a processor with 2 cores and hyperthreading would be reported as a processor with 4 cores. To count the number of processing units use grep with wc $ cat /proc/cpuinfo | grep processor | wc -lĤ The number of processors shown by /proc/cpuinfo might not be the actual number of cores on the processor.

The /proc/cpuinfo file contains details about individual cpu cores. There are quite a few commands on linux to get those details about the cpu hardware, and here is a brief about some of the commands. The cpu information includes details about the processor, like the architecture, vendor name, model, number of cores, speed of each core etc.
