You also can use other tools for system monitoring but those are not installed by default on Linux.

#Less proc cpuinfo how to

In this guide you learned how to show get CPU information and the know about the CPU structure.

You can know about the CPU architecture using lscpu command. It will show output something like below: For instance, to show only processor name, type: grep -m 1 'model name' /proc/cpuinfo You also can filter the output using grep command.

model name – It shows the full name of the processor with the brand name.

processor – It’s the identification number for the each processor and starts from 0.

Now we will utilize the ‘grep’ and ‘cat’ command to only extract the information about the CPU speed from this file.

The /proc/cpuinfo file has all content related to the individual CPU cores.

Here, in this example, there are 4 cores processor so it will show list of all cores from 0 to 3. Wildcards are allowed.It will show the logical CPU with identification number. cat /proc/cpuinfo displays various information about your CPU. Append "| grep devtype" to look up specific devices, such as hard drives. Version - shows current version and distribution of your OSĭevices - shows a list of all attached devices (including system buses and available ports). Append "| grep Total" to see your total system RAM. Continue to view the /etc/sysconfig entries in this file. Press n (lowercase for next) to display the next instance of the string. While viewing the file using the less command, use the slash (/) key followed by etc/sysconfig to search for this string. Meminfo - shows information about your system memory (RAM). Search the contents of the sysconfig.txt file for /etc/sysconfig. Append "| grep model" to see your CPU's model number. Important /proc filesĬpuinfo - shows information about your CPU. "| grep total" will not work, but "| grep Total" will. Keep in mind that Linux is case-sensitive, so if you cannot find the line you need, but believe it should be there, capitalize the first letter. x86info x86info is a program which displays a range of information about the CPUs present in an x86 system. This is the closet tool to CPU-Z app on Linux. cpuid command Dump CPUID information for each CPU.

x86info command Show x86 CPU diagnostics. You can append | grep parameter at the end of your command to only display lines that contain your parameter. lscpu command Show information on CPU architecture. Or cat /proc/cpuinfo grep command to quickly find needed information Most files that hold system information can be found in /proc, such as /proc/mdstat.Įasiest way to read them is to use either the less, or cat command to to read them: less /proc/cpuinfo Find your system information in Linux through the command line.
