.SH Description


The uftp is user interactive and non-interactive program to the ARPANET File Transfer Protocol (RFC959).
The uftp allows user to transfer files, group of files in foreground and background modes. uftp runs on the client host.


.SH Basic features



Auto retrying of connection to remote node until it is succeeded.
.PP
Automatic reconnection with continue to transfer if the connection was broken.
.PP
Several sessions (frames) at once. Dynamically switching between them. 
.PP
Setup commands, which are executed after "open" and "cd" commands. (aliases autologin & autocd )
.PP
Cleaning timeout on the remote server.
.PP
The user can setup any system parameters, like timeouts, reconnect delays, default port number,
automatic binary mode, automatic "hash" mode and interval to clean timeouts on FTP server.
.PP
User can setup the prompt with the descriptions of local and remote directories, full or short site name, 
time, frame number,
remote user's name, port number, timeout, process identification.
.PP
Several commands in one line.
.PP
Aliases with arguments, which may contain few commands separated by ';'.
.PP
Redirection input/output irrespective of context or/and command.
.PP
The local files are libftp-files, which split on local files, pipes and ftp-files. This particular file specification
can be used in any context, including for file names of redirection input/output streams.
.PP 
Any command may be executed in background mode, though the current frame is not droped out and user can continue
his work.
.PP
Creation of alias described the current frame, and save all exist aliases to personal 
automatic startup file, which is differ from startup file. This file user can make himself.


.SH Environment description



Command line mode supports all edit key bindings. (uftp using readline library). 
Before each command user can see the prompt with description of current frame.
If debug mode is enabled user see the protocol between uftp and ftp-daemon (ftpd).

.SH Libftp file specification

All local files interpret as libftp's files. Libftp responds to three types of files such
 as local file, ftp files and program
pipes. All files can be described as next syntax:

   |string - interprets string as shell command, which must be \
   executed with appropriate input/output for file. It depends where
   this file is specified.

   hostname:filename - interprets as file, which must be taken
   using ftp protocol with anonymous access

   user@hostname:filename - interprets as file accesses via ftp
   with password yourname@your_host.your_domain

   user/pass@hostname:filename - also ftp file.

   *STDIN*, *STDOUT*, *STDERR* or char '-' - opened streams.

   anything - local file name.

.SH String syntax

The strings starting from char '!' interpret as shell command.
The strings or aliases containing one or few char ';' will be executed as a chain commands.
The chains of characters between  " or ' interpret as one set without syntax resolving.
In any command string user can redirect input or/and output 
using char > and < . For the complex file name it must quoted by ' or ". 

Examples:

	dir >filename

	cat filename >'|mail -s "my files" fiend@hostname.domain' 

	dir -R etc bin >"|gzip >result.gz"

	cat filename > user/password@hostname:/dir/filename.ext

	put - < "|finger @hostname" newfile.finger
