- Connect to remote sftp server
- Navigation in file system
- Upload files to SFTP server
- Download files from SFTP server
- Close SFTP connection
Connect to Remote SFTP Server
Use sftp command-line utility to connect remote sftp system. You need the sftp user and hostname or IP address of the remote host.
sftp [email protected]
Enter sftpuser account password to connect:
[email protected]'s password: sftp>
Navigate and View Files
Navigation in directories on SFTP is as simple as the local system. Use ‘pwd’ command to check the current working directory.
pwd
Remote working directory: /
Then use the ‘ls’ command to list all files and directories in the current directory.
ls
To navigate to other directories use ‘cd’ command followed by destination directory.
cd uploads
Use ‘cd ..’ to navigate to the parent directory.
cd ..
Upload files to SFTP
Now, I need to upload some files under uploads directory. Use the ‘put’ command to upload README.md from the local system to the remote sftp directory.
put README.md
You can also provide the absolute path of the local file and remote directory without navigating directories.
put /var/www/README.md /uploads/20191115/
Download Files from SFTP
To download files from the remote sftp directory use the ‘get’ command. For example to download REMOTE_FILE.md from the remote system to the current local directory.
get REMOTE_FILE.md
Similarly, you can provide an absolute path to download files.
get /uploads/REMOTE_FILE.md /var/www/
Quit the SFTP Connection
Simply say bye to your remote SFTP server. This will disconnect the SFTP connection and return to your local shell.
bye
Alternatively, you can also use quit or exit commands to close the SFTP session.
Conclusion
