As you begin to write programs and build files, you will eventually need help in finding your files and folders. This is where the Linux “find” command comes in. In this video we explore use of the find command and demonstrate how use of find with wildcards and pipes creates a powerful combination.
We saw in earlier lessons how we can use Linux pipes to send the output from a command or program to another command or program. In this lesson we learn to use “tees” to send the output to multiple places.
Just as pipes are used in the real world to connect one tank to another, in Linux we can use pipes to connect one command to another. With a pipe, we can take the output of one command and “pipe” it to become the input of another command. Pipes are one of the really powerful techniques that can be used in Linux, and this video shows you how to use them.
A key to becoming an expert in Linux is mastering the technique of creating good path names to your files and folders. This lesson reviews material from earlier lessons, plus looks at some additional techniques for quickly getting to the file or folder you are looking for.
The standard boot configuration of the Raspberry pi can lead to some characters not working properly on US keyboards. In particular, the shift-number characters like !,~,# can not be where you expect them. The easiest way to fix this is to edit the nano /etc/default/keyboard file. The following should fix things for you.
$ sudo nano /etc/default/keyboard
Then on the line for XKBLAYOUT change it to:
That should make your pi work properly with most US keyboards.
