Understanding File Transfer Commands
File transfer commands are vital for copying files between computers, whether on the same network or across the internet. Below are some of the most commonly used file transfer commands in Linux, complete with syntax and practical examples.
1. scp [source] [user]@[host]:[destination]
Description: scp (Secure Copy Protocol) is used to securely transfer files between hosts on a network. It uses SSH for data transfer, ensuring security.
Syntax:
scp [source] [user]@[host]:[destination]Example:
$ scp myfile.txt user@example.com:/home/user/This command copies myfile.txt to the specified directory on example.com.
2. rsync -avz [source] [user]@[host]:[destination]
Description: rsync is a powerful tool for synchronizing files and directories between two locations. The -a option preserves permissions, -v enables verbose mode, and -z compresses file data during the transfer.
Syntax:
rsync -avz [source] [user]@[host]:[destination]Example:
$ rsync -avz myfolder/ user@example.com:/home/user/This command synchronizes the contents of myfolder with the specified directory on example.com.
3. ftp [host]
Description: ftp (File Transfer Protocol) is a standard network protocol used for transferring files. It’s often used for accessing and transferring files to and from servers.
Syntax:
ftp [host]Example:
$ ftp example.comThis command connects to the FTP server at example.com. After connection, you can use commands like get, put, and ls to manage files.
4. sftp [user]@[host]
Description: sftp (Secure File Transfer Protocol) provides a secure way to transfer files over SSH. It offers an interactive interface similar to ftp.
Syntax:
sftp [user]@[host]Example:
$ sftp user@example.comThis command initiates an SFTP session, allowing you to securely transfer files.
5. wget [url]
Description: wget is a command-line utility for downloading files from the web. It supports HTTP, HTTPS, and FTP protocols.
Syntax:
wget [url]Example:
$ wget https://example.com/myfile.zipThis command downloads myfile.zip from the specified URL.
6. curl -O [url]
Description: curl is a versatile tool for transferring data from or to a server using various protocols. The -O option saves the downloaded file with the same name as in the URL.
Syntax:
curl -O [url]Example:
$ curl -O https://example.com/myfile.zipThis command downloads myfile.zip from the specified URL.
