How to view Linux kernel parameters for currently booted system

To view the Linux kernel parameters for the currently booted system, you can use the sysctl command. For example:

sysctl -a

This will show a list of all the kernel parameters that are currently set on the system. The output will include the name of the parameter and its current value.

You can also use the sysctl command to view the value of a specific kernel parameter. For example:

sysctl kernel.ostype

This will show the value of the kernel.ostype parameter.

Keep in mind that some kernel parameters can only be set at boot time, and cannot be changed once the system is running. In this case, you will need to edit the kernel command line in the bootloader configuration to change the value of the parameter.

You can also view the kernel parameters by looking at the /proc/cmdline file. This file contains the kernel command line that was used to boot the system, and includes all of the kernel parameters that are currently set. You can view the contents of this file by using the cat command:

cat /proc/cmdline

This will show the kernel command line and all of the kernel parameters that are currently set on the system.
