I wanted to get an idea about UNIX file transfer protocols. It would be of great help if you could say about mput in UNIX.

mput is used to copy multiple or many files from the local machine to the remote machine. It is done by using the following syntax namely
ftp> mput filenames

Here each time the command prompt or in other words the user is prompted with yes or no answer before the process of transferring of each file takes place.
