Feel free to also do this with a code editor, if you've used one already! |
For the sake of having demonstration, we'll also want to have another text file that's somewhat larger - we'll use the King James Bible, which you can store in a text file named james.txt
with the following command (don't worry, we'll cover this later as well):

Viewing Files
To view the text of a file in the terminal, the first command we can use is the cat
command (short for concatenate), which takes in as an argument the file we want to view the text of, and simply prints it all to the terminal:

The commands discussed in this section will have permanent, irreversible effects. Use them with caution and at your own risk. Unless you are certain that you will never need the files again, it is recommended that you instead move them to a temporary location (C2S2 will likely come up with a command to automatically do this, poke Aidan or the team lead if you want it sooner ) |

Addendum: Downloading Files from the Web
Alright; while we're at it, let's revisit our wget
command from before, which is installed on many systems, including the C2S2 server. wget
takes in a file that is located on the internet, and downloads the file to your current directory. For example, if we wanted to download the Bill of Rights, we might do so with the following command:
Code Block | ||||
---|---|---|---|---|
| ||||
wget http://www.textfiles.com/anarchy/billofrights.txt |
Note that this will store it as the original file name, billofrights.txt
. Previously, we used the O
flag, which specified that we wanted the new file name to be the next argument.
