Connect through abstract Unix socket instead through a network. Enable alt-svc parser. Example: curl --alt-svc svc. Append to the target file. Use AWS V4 signature authentication. Use HTTP basic authentication. Use the specified file for certificate verification. Example: curl --cacert CA-file. Use the specified directory to look for the certificates.
Verify the server certificate status. Specify the type of the provided certificate. Use the provided certificate file when working with a SSL-based protocol. Provide ciphers to be used in the connection. Enable built-in SSH compression. Request to receive a compressed response. Provide a text file with curl arguments, instead of writing them on the command line. Example: curl --config file. Specify maximum time a curl connection may last.
Provide a connection rule to direct requests at a specific server cluster node. Example: curl --connect-to example. Resume file transfer at the offset specified. Specify a file for storing cookies. Read cookies from a file. Create the local directories for the --output option.

If the specified directory does not exist, curl will attempt to create it.

If you want to download multiple files with a single command, you have to add the sizeof-r to the cURL. Side Projects: Yay or Nay?
