File Transfer Protocol (FTP) was widely used protocol to transfer files or data remotely in unencrypted format which is not secure way to communicate. As we all know that File Transfer Protocol is not at all secure because all transmissions happens in clear text and the data can be readable by anyone during sniffing the packets on the network.

10 sftp command examples

So, basically FTP can be used in limited cases or on the networks that you trust. Over the period of time SCP and SSH addresses this security ambiguity and added an encrypted secure layer while transferring data between remote computers.

SFTP (Secure File Transfer Protocol) runs over SSH protocol on standard port 22 by default to establish a secure connection. SFTP has been integrated into many GUI tools (FileZilla, WinSCP, FireFTP etc.).

Security Warnings: Please don’t open SSH port (Secure SHell) globally as this would be a security breaches. You can only open for specific IP from where you are going to transfer or manage files on remote system or vice versa.

This article will guide you 10 sftp command examples to use it through interactive command-line interface.

1. How to Connect to SFTP

By default, same SSH protocol is used to authenticate and establish a SFTP connection. To start an SFTP session, enter the username and remote hostname or IP address at the command prompt. Once authentication successful, you will see a shell with an sftp> prompt.

[root@tecmint ~]# sftp tecmint@27.48.137.6

Connecting to 27.48.137.6...
tecmint@27.48.137.6's password:
sftp>

2. Getting Help

3. Check Present Working Directory

The command ‘lpwd‘ is used to check the Local present working directory, whereas ‘pwd‘ command is used to check Remote working directory.

sftp> lpwd
Local working directory: /
sftp> pwd
Remote working directory: /tecmint/
  1. lpwd – print the current directory on your system
  2. pwd – print the current directory on the ftp server

4. Listing Files

Listing files and directories in local as well as remote system.

On Remote
sftp> ls
On Local
sftp> lls

5. Upload File

Put single or multiple files in remote system.

sftp> put local.profile
Uploading local.profile to /tecmint/local.profile

6. Upload Mutiple Files

Putting multiple files on in remote system.

sftp> mput *.xls

6. Download Files

Getting single or multiple files in local system.

sftp> get SettlementReport_1-10th.xls
Fetching /tecmint/SettlementReport_1-10th.xls to SettlementReport_1-10th.xls

Get multiple files on a local system.

sftp> mget *.xls

Note: As we can see by default with get command download file in local system with same name. We can download remote file with different name specifying the name at the end. (This applies only while downloading single file).

7. Switching Directories

Switching from one directory to another directory in local and remote locations.

On Remote
sftp> cd test
sftp>
On Local
sftp> lcd Documents

8. Create Directories

Creating new directories on local and remote locations.

sftp> mkdir test
sftp> lmkdir Documents

9. Remove Directories

Remove directory or file in remote system.

sftp> rm Report.xls
sftp> rmdir sub1

Note: To remove/delete any directory from remote location, the directory must be empty.

10. Exist sFTP Shell

The ‘!‘ command drop us in local shell from where we can execute Linux commands. Type ‘exit‘ command where we can see sftp> prompt return.

sftp> !

[root@sftp ~]# exit
Shell exited with status 1
sftp>

The SFTP is a very useful tool for administrating servers and transferring files to and from (Local and Remote). We hope this tuts will help you to understand the usage of SFTP in some extent.

    Hi,

    Generally it will prompt to enter password if we enter SFTP command.
    Is it possible to enter the password into the SFTP command so that I do not see a prompt again asking for password.

    Could you please suggest the syntax,

    My SFTP command is like this, then it will ask for a password say ‘passboss’
    sftp -o StictHostKeyChecking=no -oProxyCommand=’/usr/bin/nc -abcdef.kk.lmmm:1080 %h %p’ user@kkkk.jjjjj.com 22

    Could you please add the password in the above syntax so that it will not prompt again.

    eagerly awaiting ur reponse.

    Regards,
    Kamal

    use sftp –password=”passboss”

  3. david says:

    sftp will not pass along a password as a parameter and you cannot script reading the password. You must either manually enter the password or use RSA keys to bypass using passwords. Search for “sftp rsa key password” and you will find many examples of how to do this. (This drove me crazy when I was first learning sftp, I was used to scripting the password for ftp).
