Question

mkdir

Answer 1

making a folder, which just involves using the mkdir command and again providing the name that we want to assign to the directory. For example, creating the directory "mydirectory" using mkdir mydirectory. ex: tryhackme@linux2:~$ mkdir mydirectory tryhackme@linux2:~$ ls folder1 mydirectory note

Answer 2

Determining File Type ex: tryhackme@linux2:~$ file note note: ASCII text

Answer 3

To create or edit a file using nano, we simply use nano filename -- replacing "filename" with the name of the file you wish to edit. ex: tryhackme@linux3:/tmp# nano myfile Once we press enter to execute the command, nano will launch! Where we can just begin to start entering or modifying our text. You can navigate each line using the "up" and "down" arrow keys or start a new line using the "Enter" key on your keyboard. Nano has a few features that are easy to remember & covers the most general things you would want out of a text editor, including: Searching for text Copying and Pasting Jumping to a line number Finding out what line number you are on You can use these features of nano by pressing the "Ctrl" key (which is represented as an ^ on Linux) and a corresponding letter. For example, to exit, we would want to press "Ctrl" and "X" to exit Nano.

Answer 4

This command allows us to download files from the web via HTTP -- as if you were accessing the file in your browser. We simply need to provide the address of the resource that we wish to download. For example, if I wanted to download a file named "myfile.txt" onto my machine, assuming I knew the web address it -- it would look something like this: ex: wget https://assets.tryhackme.com/additional/linux-fundamentals/part3/myfile.txt

Answer 5

Secure copy, or SCP, is just that -- a means of securely copying files. Unlike the regular cp command, this command allows you to transfer files between two computers using the SSH protocol to provide both authentication and encryption ex: Copy files & directories from your current system to a remote system Variable Value The IP address of the remote system 192.168.1.30 User on the remote system ubuntu Name of the file on the local system important.txt Name that we wish to store the file as on the remote system transferred.txt -With this information, let's craft our scp command (remembering that the format of SCP is just SOURCE and DESTINATION) command: scp important.txt ubuntu@192.168.1.30:/home/ubuntu/transferred.txt -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- And now let's reverse this and layout the syntax for using scp to copy a file from a remote computer that we're not logged into: ex: Variable Value IP address of the remote system 192.168.1.30 User on the remote system ubuntu Name of the file on the remote system documents.txt Name that we wish to store the file as on our system notes.txt The command will now look like the following: command: scp ubuntu@192.168.1.30:/home/ubuntu/documents.txt notes.txt
