How to check OS version using Linux command line
Most folks recall to mind Linux as an operating machine however it’s actually a kernel; A kernel is a bridge between the software and {hardware} of a pc. Linux-based working methods are in truth known as Linux distributions which generally come with the Linux kernel in conjunction with instrument package deal managers, instrument, and graphical person interface.

sudo apt set up lsb-release
The apt is the package deal supervisor in Debian-based methods.
If you simplest need the model quantity as an alternative of the entire LSB knowledge then use the next command:
lsb_release -d
Check Linux model from the /and so forth/factor
record
The /and so forth/factor is a straightforward textual content record that has the identity knowledge of the machine. This knowledge is imprinted on the display sooner than the login suggested. Use the below-given command to show the contents of the record at the command line interface:
cat /and so forth/factor
Check Linux OS model from the /and so forth/os-release
record
