Again, assuming the connection is approve and the login is successful, the remote file will download from the target server to the localhost. Using ssh for remote file downloads like this is most appropriate for secure transfers which require authentication.
Sure you can also downloading files with curl or wget from remote servers, but files accessible with curl and wget tend to be accessible from the outside world as well, whereas ssh and scp requires authentication or a key, and uses 3DES encryption, making it considerably more secure.

I was to send a file from 1 remote system, to another remote system without downloading the file.
The problem is i want to have the 2nd remote system forward not download that file to a 3rd remote session. Finally, if there are multiple files with similar naming patterns such as file extensions, wildcards work well:. Name required. Mail will not be published required. Secondly, you should accurately specify the relative path to your download file location on the remote server and the relative path to the download file storage location on your desktop computer.
You can achieve successful file downloads from a remote Linux server environment to a Linux desktop environment through three techniques.
Before we reference the three SCP file download techniques, let us first have some files on our server that we wish to download.
If these files already exist on your end, you are good to go. In reference to the above syntax rule, we can download our first file with the following approach from your desktop environment. In this example, curl detects that the output is being redirected to a file and that it is safe to generate the progress information.
Double-clicking that file will open your default browser so that it displays the retrieved web page. Note that the address in the browser address bar is a local file on this computer, not a remote website. We can create a file by using the -o output option, and telling curl to create the file. To have the text-based download information replaced by a simple progress bar, use the - progress bar option. It is easy to restart a download that has been terminated or interrupted.
To restart the download, use the -C continue at option. This causes curl to restart the download at a specified point or offset within the target file.
If you use a hyphen - as the offset, curl will look at the already downloaded portion of the file and determine the correct offset to use for itself. Using xargs we can download multiple URLs at once. Perhaps we want to download a series of web pages that make up a single article or tutorial. This is the command we need to use to have xargs pass these URLs to curl one at a time:. The -n 1 option tells xargs to treat each line of the text file as a single parameter.
Checking in the file browser shows the multiple files have been downloaded. Each one bears the name it had on the remote server.
Using curl with a File Transfer Protocol FTP server is easy, even if you have to authenticate with a username and password. This is a free-for-testing FTP server hosted by Rebex. Use the same command as a moment ago, with the filename appended to it:. In almost all cases, it is going to be more convenient to have the retrieved file saved to disk for us, rather than displayed in the terminal window.
Once more we can use the -O remote file output command to have the file saved to disk, with the same filename that it has on the remote server. The file is retrieved and saved to disk. We can use ls to check the file details. It has the same name as the file on the FTP server, and it is the same length, bytes.
Some remote servers will accept parameters in requests that are sent to them. The parameters might be used to format the returned data, for example, or they may be used to select the exact data that the user wishes to retrieve.
