Downloading a large file using curl

To download a large file using curl, use the following command:

Example of downloading a large file using curl

curl -O [URL]

Replace [URL] with the URL of the file you want to download. For example:

curl -O http://example.com/large_file.zip

This will download the file and save it to the current working directory with the same name as the file on the server.

You can also specify a different name for the file using the -o option:

curl -o my_file.zip http://example.com/large_file.zip

To download a file from a password-protected server, use the -u option followed by your username and password:

curl -u username:password -O http://example.com/protected_file.zip

If you want to download a file from a server that uses a self-signed SSL certificate, you can use the -k option to disable certificate verification:

curl -k -O https://example.com/large_file.zip

You can also use the --progress-bar option to display a progress bar while the file is being downloaded:

curl --progress-bar -O http://example.com/large_file.zip

Finally, you can use the --limit-rate option to limit the download speed to a specified number of bytes per second. For example, to limit the download speed to 1000 bytes per second, use the following command:

curl --limit-rate 1000 -O http://example.com/large_file.zip

To run this command from a PHP script, wrap it in exec() or shell_exec().
