## How to Use SFTP to Securely Transfer Files with a Remote Server
This article is a quick tutorial on how to use Secure File Transfer Protocol (SFTP) to exchange files with a server. This is useful for programming, as it allows you to code and test locally, and then send your work to the server when you are done.

### Testing SSH
If you haven't already, test that you are able to SSH into the server. SFTP uses the Secure Shell (SSH) protocol, so if you are unable to SSH you probably won't be able to SFTP either.

```bash
ssh your_username@hostname_or_ip_address
```
### Start SFTP Session
This uses the same syntax as SSH and opens a session in which you can transfer files.
```bash
sftp your_username@hostname_or_ip_address
```
To list helpful commands:
```bash
help
```
### Transfer files and folders

To download a file:
```bash
get <filename>
```
To download a folder and its contents, use the "-r" flag (also works for uploading):
```bash
get -r <foldername>
```
To upload a file:
```bash
put <filename>
```

### Change folders
To change the local folder:
```bash
lcd <path/to/folder>
```
To change the remote folder:
```bash
cd <path/to/folder>
```

### Quit sftp.
Once done with file transfer you can exit SFTP prompt using `bye` command
`sftp> bye`

For more info on SFTP use 'man sftp' in linux terminal.
