Some cool quick Linux command line tricks

Filed under
HowTos

If you’ve used Linux long enough, you know there are some seriously cool tricks you can pull from the command line. Some of these tricks are just for fun, but the vast majority of them actually serve a purpose. It is the latter type of trick I want to highlight here. The purpose they serve will all vary so you might only find one or two that are of use to you. But no matter if you find a command you can use immediately, you might be able to find one that you can modify to fit some need or other. With that said, let’s dig in.

Proposed: A Tainted Performance State For The Linux Kernel

Similar to the kernel states of having a tainted kernel for using binary blob kernel modules or unsigned modules, a new tainting method has been proposed for warning the user about potentially adverse kernel performance. Dave Hansen of Intel has proposed a new "TAINT_PERFORMANCE" for the kernel that would proactively print a warning message about not using the kernel for any performance measurements. Dave explained in his RFC announcement, "I have more than once myself been the victim of an accidentally-enabled kernel configuration option being mistaken for a true performance problem. I'm sure I've also taken profiles or performance measurements and assumed they were real-world when really I was measuring the performance with an option that nobody turns on in production. A warning like this late in boot will help remind folks when these kinds of things are enabled." Read more
