Here, [options] represent additional flags that modify the behavior of the download process, [url] is the URL of the file you want to download, and [output_file] is the name of the file you want to save the downloaded content as.

For example, to download a file named “example.zip” from a given URL and save it as “downloaded_file.zip,” you can use the following command:

$ curl -o downloaded_file.zip https://example.com/example.zip

Curl also provides options to resume interrupted downloads, just like wget. You can use the -C – flag to resume a previously interrupted download:

$ curl -C - -o downloaded_file.zip https://example.com/example.zip

In addition to basic file downloads, curl offers various features, such as downloading multiple files in parallel, handling authentication, and sending custom headers. It also supports post-processing of downloaded files directly from the command line.

Furthermore, curl supports the use of cookies, which can be useful when downloading files that require authentication or session tracking. You can store and reuse cookies across multiple requests using the -c and -b options, respectively.

Similar to wget, curl provides a wide range of options to tailor the download process to your specific needs. You can refer to the curl documentation or use the –help flag to explore these options:

$ curl --help

Whether you need to download a single file, transfer data with different protocols, or customize your download requests, curl is a powerful tool that offers flexibility and reliability for file downloading in Linux.

 

Using the FTP Protocol to Download Files

When it comes to downloading files in Linux, the File Transfer Protocol (FTP) is a commonly used protocol. FTP allows you to transfer files between a local machine and a remote server using dedicated commands.

To initiate an FTP connection, you can use the ftp command followed by the hostname or IP address of the FTP server:

$ ftp [hostname/IP]

Once connected, you can navigate through the remote server’s directory structure using commands such as ls (list), cd (change directory), and pwd (print working directory).

To download a file from the remote server, you can use the get command followed by the filename:

ftp> get [filename]

The downloaded file will be saved in the local directory where you initiated the FTP connection.

FTP also provides options for resuming interrupted downloads. If a download is interrupted, you can use the reget command followed by the filename to resume the download:

ftp> reget [filename]

In addition to basic file downloads, FTP also supports transferring directories and downloading multiple files in a single command. You can use the mget command followed by the wildcard pattern or filenames to download multiple files:

ftp> mget [pattern/filenames]

It’s worth noting that FTP connections are often unencrypted by default. To establish a secure FTP connection, you can use the sftp command, which implements the Secure Shell (SSH) protocol for secure file transfers.

Similar to other methods, FTP provides various options and commands to customize your download process, manage remote files, and control the transfer mode. You can refer to the FTP documentation or use the help command within the FTP session to explore these options.

Using the FTP protocol is an efficient and reliable way to download files in Linux, providing you with the ability to transfer files between machines securely and with ease.

 

Using the SCP Command to Download Files

Another method for downloading files in Linux is through the secure file copying utility, SCP. SCP utilizes the Secure Shell (SSH) protocol to securely transfer files between hosts.

The basic syntax for using SCP is:

$ scp [options] [username@]host:source_path destination_path

Here, [options] represent additional flags that modify the behavior of the SCP command, [username@]host refers to the remote host and optional username, source_path is the path of the file you want to download on the remote host, and destination_path is the directory where the downloaded file will be saved on your local machine.
