In the AWS EC2 Management Console, click on Instances in the left menu (1) under EC2 Dashboard. Click on the Connect button (2) to open the Connect To Your Instance window.; You will copy and paste information from this window to your Mac Terminal window later. Next, open a Terminal window on your Mac and navigate using the cd (change directory) command to the folder containing the private. I need to download a file from server to my desktop. (UBUNTU 10.04) I don't have a web access to the server, just ssh. If it helps, my OS is Mac OS X and iTerm 2 as a terminal.
You may not realize it, but your Mac already runs a variant of UNIX. You can easily access a terminal window to use your computer's built-in UNIX functionality with the 'Terminal' program (Applications/Utilities/Terminal.app). You may want to make a shortcut to this program in your Dock, since you'll be using it a lot from now on. Similarly, you can use your Mac directly to log into a UNIX server, and even to transfer files to/from a UNIX server.

Enabling X11-Forwarding (Popping up windows from the UNIX server)
Your Mac comes with another program that enables you to display graphics from programs running on a remote UNIX/Linux server, called 'XQuartz' (Applications/Utilities/XQuartz.app). On older OS X systems this program was called 'X11' and was located in essentially the same location. If neither of these programs are currently installed on your Mac, you can download XQuartz from the Mac App Store (free).
To enable forwarding, just run XQuartz/X11 before starting Terminal. If a xterm window pops up from XQuartz/X11, you may close that window before starting Terminal, since Terminal is more feature-rich than XTerm (my opinion). Once XQuartz/X11 is running, when you log into remote UNIX servers (as shown in the next section) you should be able to display remote graphics.
Logging into an UNIX server
The standard protocol for logging into a modern UNIX server is through using a Secure SHell (SSH) client. OS X has built-in SSH functionality, through the 'ssh' command in the Terminal.
To use ssh from the Terminal:
- Open Terminal.
- At the command line, type
ssh username@hostname -CY
orssh username@hostname -CX
(the Y vs X difference is minimal, and will not affect your user experience, just remember to use one of them). Here, username is your user name on the UNIX server, and hostname is the name of the UNIX server. For example, I could log into the UNIX server titan.smu.edu with the commandssh [email protected] -CY
For additional information on using ssh, type

man ssh
(short for manual) in the Terminal window.
Transferring files to and from a UNIX server (terminal)
You may copy files to and from a UNIX/Linux server in the Terminal window as well, using the 'scp' command. The syntax is either
scp file_to_copy_from username@hostname:file_to_copy_to
or
scp username@hostname:file_to_copy_from file_to_copy_to
depending on whether you want to copy the file to or from the UNIX server. For example, suppose I have a file named 'file1' in my home directory on titan, and I want to copy it to the current directory on my Mac (the one the terminal is in, type 'pwd' to see which directory you are in if unsure):
scp [email protected]:file1 .
or
scp [email protected]:file1 file1
would give the desired result. Suppose now that I have the file 'file2' in the current directory on my Mac that I want to copy to my home directory on titan:
scp file2 [email protected]:
![Mac Terminal Download File From Server Mac Terminal Download File From Server](/uploads/1/2/6/6/126694708/338701268.png)
or
scp file2 [email protected]:file2
would do the trick. For more information on the 'scp' command, type man scp in the terminal.
Transferring files to and from a UNIX server (graphical)
Fetch
One of the most popular graphical file transfer options in OS X is the program Fetch. This is not a free program.
To use Fetch, fill in the UNIX hostname (e.g. titan.smu.edu), your username on that host (e.g. reynolds), and your password on that host, then click 'Connect'. You will then see a display of your remote directory on the UNIX server. Transfer files by dragging them to and from the Finder.
FileZilla
A free alternative to Fetch that may be used from OS X, Windows and Linux is is FileZilla. To install FileZilla in OS X:
Mac Terminal Download File From Server Using Ssh
- Download the FileZilla client for Mac OS X from here.
- Open the FileZilla installation file to unpack the application.
- You may run Filezilla.app from the Desktop, or you can instead move it to your Applications folder.
To use FileZilla, fill in the fields for the host (e.g. titan.smu.edu), your username on that host (e.g. reynolds), your password, and the port (use 22 for SFTP), and hit [return]. You should notice two file browser windows open up, the browser on the left is on your computer, the browser on the right is from the UNIX host (e.g. titan). Transfer files by dragging them from one computer to the other with your mouse.

You can use FTP to transfer files from your Mac OS X Snow Leopard computer with an FTP server by using the command-line interface (CLI); to use the CLI, open a Terminal, or shell, session. To use a Terminal session, double-click the Terminal icon in the Utilities folder inside the Applications folder. When you open a Terminal session, you’re presented with a window that accepts text commands. You’ll see a prompt that consists of your computer’s name and the folder that you’re currently in, followed by your user ID. It’s at this prompt where you type various FTP commands.
After you’re in the Terminal session, you’ll use a series of commands to connect to another computer, move in and out of folders, and transfer files. Following is a list of the basic commands that you need to use FTP as well as a brief description of what each command does.
- ftp: This command starts the FTP command line interface session. You can tell that you’re in the FTP client application when you see ftp> as your command prompt. This is where you type all other FTP commands to do things.
- open:This command is used to start your connection to another computer. Type this command followed by the IP address of the FTP server that you want to connect to.
- ls: Use this command to see a listing of all files and folders in the current folder on the FTP server.
- cd:This command allows you to change the folder that you’re in. Type cd <folder> (where folder is a specific folder name) to move into a subfolder on the FTP server. Type cd .(that’s c, d, space, and two periods) to go back out a folder level.
- lcd: This command acts exactly like cd except that it changes the folder that you’re currently in on your local system, not the FTP server. Use this command to put yourself in the folder on the local drive that you want to transfer files to and from.
- bin: Type this command to get in binary mode to transfer files that aren’t plain-text files. (Always use binary mode unless you’re specifically transferring plain-text files.)
- ascii: This command puts you in ASCII mode for transferring text files.
- getormget: To retrieve a single file, use the get command followed by the filename of the file that you want to retrieve. https://greatbrown672.weebly.com/signblazer-elements-for-mac-free-download.html. If you want to get multiple files at one time, use the mget command followed by a filename, possibly containing * and/or ? as wildcards.
- putormput: To send a single file, use the put command followed by the filename to send a file to the FTP server. To send multiple files, use the mput command followed by a filename, possibly containing * and/or ? as wildcards.
- quit: Use the quit command to end your FTP session.
To end a Terminal session and exit Terminal at any time, press Command+Q. Terminal prompts you for confirmation if necessary.
Using these commands will enable you to exchange files with an FTP server. Here’s an example of how to use these commands within the Terminal window:
- Type ftp to get into FTP mode.
- Type open<ip address> (whereip address is the server’s network IP address)to open your connection to the FTP server.
- At this point, you’re asked for a username and password.For many FTP servers, using the username anonymous and your e-mail address as the password is enough to get you logged in. Some sites even allow you to log in without any username or password at all. On secure sites, however, you must use an assigned username and password provided by the administrator of that particular server.
- Type lcd<folder> (where folder is a specific folder name) to change into the folder on your local drive that you want files to come to or from.
- Type the ls and cd commands to place yourself into the desired folder on the FTP server.
- Type the ascii or bin command to set your file transfer mode to ASCII or binary, respectively.This is important because choosing the wrong type will likely cause the transfer to fail. Unless it’s a plain-text file, always use binary mode.
- Type the get, mget, put, and mput commands to send or receive the desired files.
- Type the quit command to close the connection and exit the FTP session.
