atftp (1)

atftp [options] [host [port]]

atftp can be used interactively or in batch mode to retrieve files from TFTP servers. When used interactively, a summary of the commands can be printed by typing 'help'. This TFTP client support all basic features from RFC1350, RFC2347, RFC2348 and RFC2349. It also support multicast implementation of RFC2090 and mtftp as defined in the PXE specification.

This program supports both the usual GNU command line syntax, with long options starting with two dashes ('--') as well as short options. Some options are usable in batch mode only, they have no meaning when atftp is use interactively. A description of the options is shown below.

-g, --get

-p, --put
