Long: upload-file Short: T Arg: Help: Transfer local FILE to destination --- This transfers the specified local file to the remote URL. If there is no file part in the specified URL, curl will append the local file name. NOTE that you must use a trailing / on the last directory to really prove to Curl that there is no file name or curl will think that your last directory name is the remote file name to use. That will most likely cause the upload operation to fail. If this is used on an HTTP(S) server, the PUT command will be used. Use the file name "-" (a single dash) to use stdin instead of a given file. Alternately, the file name "." (a single period) may be specified instead of "-" to use stdin in non-blocking mode to allow reading server output while stdin is being uploaded. You can specify one --upload-file for each URL on the command line. Each --upload-file + URL pair specifies what to upload and to where. curl also supports "globbing" of the --upload-file argument, meaning that you can upload multiple files to a single URL by using the same URL globbing style supported in the URL, like this: curl --upload-file "{file1,file2}" http://www.example.com or even curl -T "img[1-1000].png" ftp://ftp.example.com/upload/ When uploading to an SMTP server: the uploaded data is assumed to be RFC 5322 formatted. It has to feature the necessary set of headers and mail body formatted correctly by the user as curl will not transcode nor encode it further in any way.
