To connect to your account using PuTTY, follow these steps:

The default port for SSH is 22.

Basic SSH Commands:
In this step, we will go through the main/most commonly used shell commands that you should learn about!
ls – This command is used to list all files and directories. Another useful option is -a, this will also show all the other files as well, which includes hidden files/directories (dot files with a . in front of them, for example: .ssh directory).
cd – This command is used to “walk” between directories (cd stands for “change directory”). Enter the command cd home and you will instantly change your current location to “home”. You can try using ls again to see that the information which was outputted to the screen has changed.
mkdir – This command is used to create a new directory (stands for “make directory”). It simply creates a new directory with your chosen name, for example mkdir NewFolder will create a new directory with a name “NewFolder” in your currently active directory (where you are right now).
rm – This command is used to remove a chosen file/directory. For example, rm NewFile will remove the previously created file named “NewFile”. If you wish to remove a directory and all the directories inside of it, use rm -r NewFolder, this will delete the folder “NewFolder” and all the other folders inside of it.
cat – This command is used to display the contents of the file. For example, cat info.txt will bring the contents of the file to the screen.
pwd – This command shows your current location in the file system. For example, type in pwd, the output could be something like this: “home/user/public_html“.
cp – This command is used to copy files and folders.
mv – This command works the same way as cp, but instead, it moves the file instead of copying it. This command can also be used to rename the file.
find – Now this command is used to search folders for a file or files that meet given criteria (name, size, file type). For example: find . -name "*.html"
vi/nano – This command is used to enter a text editor.
history – This command is used to display the last used commands. For example: history 20 will show the last 20 entered commands in the Terminal.
clear – This command clears all the text from the Terminal screen.
wgetis used to download files from the internet. For example, to fetch a file from the internet and store it in your current directory. use command:
wget http://fileurl/filename.ext
