The modern Linux kernel does the job of running applications amongst different CPU's in a multi-core architecture quite efficiently. However, if you are setting an appliance running Linux (routers, set-top boxes and so on), where services/applications are pre-determined, it might be useful to choose the CPU for given tasks/programs manually based on their resource access patterns.
In this video, you will learn how to manage CPU affinity for a process on Linux command-line.

While this is okay for legacy shells (like bourne shell), all modern shells that include bash, ksh and zsh support a for-loop syntax that somewhat resembles the C syntax. In this video, you learn how to improvize the for-loop using the modern shell syntax.

One of the standard requirements in Linux shell scripts is to get files in a directory or information about files like size, permissions, ownership, and timestamps - and the typical way to achieve this is by using 'ls' command and capturing the output. But this approach can get clumsy and error-prone as the output of ls command is not always consistent and script-friendly.
In this video, you will learn 3 alternative script-friendly approaches to get file stat, a list of files, and other details for use in shell scripts that can scale better.
