Taming The Terminal

This is the second part of a two-part installment describing the TCP/IP networking stack that allows our computers to talk to each other within our homes and offices, and to other computers and server around the world through the internet.

This is the first part of a two-part installment describing the TCP/IP networking stack that allows our computers to talk to each other within our homes and offices, and to other computers and server around the world through the internet.

In this installment we take a bit of a breather, and look at some simple tips and tricks for making like on the command line that little bit easier.

In this installment we learn how to search for files based on all sorts of criteria, including file name, file size, modified date, and more.

In this installment we learn how to use the results of a file search as the input to another command. This allows us to do things like set the file permissions on every file that ends in .php.

In this installment we look at how to use terminal commands and regular expressions to filter text, such as the output of terminal commands, and to search for files that contain a particular text pattern.

This is the second of a two-part installment where we dive deeper into Regular Expressions. This two-part installment is laying vital foundations for the up-coming installments on searching.

This is the first of a two-part installment where we dive deeper into Regular Expressions. This two-part installment is laying vital foundations for the up-coming installments on searching.

In this installment we introduce the concept of 'regular expressions' - a means of accurately describing arbitrary patterns. Regular expressions allow us to express complex search pattens in a way the computer can understand.

In this installment we continue our exploration of streams, looking at how we can use files as the source and destination for streams, and how we can combine two streams into one.

In this installment we introduce the concept of data streams, looking at the three system streams STDIN, STDOUT $ STDERR, and then look at how we can use the pipe operator connect the output of one command to the input of another.

In this installment we wrap up our look at the environment by describing command line aliases, and looking at how we can customize the prompt we see when working at the command line.

In this installment we continue to explore the environment, focusing on the very important environment variable PATH.

In this installment we introduce the rather nebulous concept of the Unix/Linux environment, and we look at environment variables and shell variables.

In this installment we look at how to read and edit text files from the command line.

Unix, Linux and OS X have a built-in manual describing how the various terminal commands work. In this installment we look at how to access this manual, and explain the special language used within.

In this installment we learn how to control processes - creating them, and ending them.

In this installment we explore the concept of Linux/Unix processes, and we introdue the ps command for viewing the running processes.

In this installment we look at file management from the commandline - creating, copying, moving, renaming, and deleting files and folders.

In this installment we’ll start by biting the bullet and dive into how to alter standard Unix File permissions. This could well turn out to be the most difficult segment in this entire series, regardless of how big n gets, but it is very important, so if you have trouble with it, please don’t give up.
