When you are completely switched to Linux like me, there are many great free programs in Windows environment like Cpuz, CCleaner, …etc. There are many ways to view your desktop/laptop’s hardware in Linux. Most of the hardware information are in /proc, for example
To view CPU information
$ cat /proc/cpuinfo
or
$ lscpu
To view ram/memory information
$ cat /proc/meminfo
To view storage information
$ sudo smartctl -a /dev/sda
or
$ sudo smartctl -a /dev/nvme0
As you can see each cpuinfo, meminfo, smartctl show everything in detail about your system’s cpu, memory, storage but you have to look for each one seperately. Luckily I found out about lshw, which is a great tool to view all of the hardware’s details of your system. lshw can show cpu, ram, motherboard, network….etc (pretty much everything). Very similar to CPUz.
To run lshw, simply run lshw command in the terminal with super-user (root) root privileges.
$ sudo lshw

If lshw give you too much information, you can make lshw give shorter output and easier to read format by adding -short option after lshe command.
$ sudo lshw -short
and the output comes with bunchs of random H/W path with no device name nor description. Scroll down to the end, lshw -short gives you kind of summary what hardware you have in your system.
