Show List of Kernel Parameters on Linux Fedora using sysctl Command

 

   The step by step command example below use the sysctl command to list kernel parameters on Linux Fedora.  The sysctl command below is execute on Linux Fedora 9 to show the list of kernel parameters and then the sysctl command output is pipe to less command to make the kernel parameters list scrollable.

sysctl command example:   sysctl -a | less

[root@fedora ~]# sysctl -a | less

[root@fedora ~]# sysctl -a | less kernel.sched_min_granularity_ns = 4000000 kernel.sched_latency_ns = 20000000 kernel.sched_wakeup_granularity_ns = 5000000 kernel.sched_batch_wakeup_granularity_ns =
