File Transfer Protocol FTP is a network protocol used for transferring files between a client and a server on a computer network. Linux Operating Systems ships with built-in FTP clients that you can easily access by entering the ftp command in your terminal. Also, when using FTP for transferring files between computers, the connection is not secure and the data is not encrypted. LFTP is a free and open source command-line utility designed for several file transfer protocols e.
It features bookmarks, job control, support for the readline library, a built-in mirror command, and support for multiple file transfers in parallel. Its features include host redialing, background processing, auto-resume downloads, filename completion, progress meters, support for other utility programs such as ncftpput and ncftpget. NcFTP is available to install from the default repositories using package manager as shown. It typically works in the command line but you can run it in a semi-GUI using ncurses.
Its features include an internal viewer that supports multiple encodings, skip-listing, remote commands for UDP call commands such as race, download, fxp, raw, idle, etc. Yafc is available to install from the default repositories using package manager as shown.

For example, the venerable vi editor ran in plain-text terminals long before the first GUI. The vi editor is one example of a screen-oriented program that draws in "text" mode, using a library called curseswhich provides a set of programming interfaces to manipulate the terminal screen. Creating programs that use curses is actually quite simple. In this article, I show an example program that leverages curses to draw to the terminal screen. One simple way to demonstrate a few curses functions is by generating Sierpinski's Triangle.
If you aren't familiar with this method to generate Sierpinski's Triangle, here are the rules:. So with those instructions, I wrote this program to draw Sierpinski's Triangle to the terminal screen using the curses functions:. Let me walk through that program by way of explanation. Otherwise, you should be able to identify the code lines that initialize and then iterate Sierpinski's Triangle, based on the above rules. Aside from that, let's look at the curses functions I used to draw the triangle on a terminal.
Most curses programs will start with these four instructions. The cbreak function disables line buffering and sets curses to take one character at a time. The noecho function tells curses not to echo the input back to the screen, and the clear function clears the screen:. The program then sets a few variables to define the three points that define a triangle.
These values tell the program how many lines and columns exist on the terminal. Screen coordinates start at zero, so the top-left of the screen is row 0, column 0. To make this easy to remember, my program sets these values in the variables maxlines and maxcolsrespectively. Two simple methods to draw text on the screen are the addch and addstr functions.
To put text at a specific screen location, use the related mvaddch and mvaddstr functions. My program uses these functions in several places.
I have seen a few programs that use simple GUI-like interfaces made out of text. A good example would be links see screenshots below. Are there any C libraries for creating this sort of thing out there?
I would ideally like mouse support but that is not strictly necessary. Screenshots of the kind of thing I want:. You could have a look at CDK-- project home page. This is a set of widgets for Menus, pulldowns etc.

Unfortunately, the only tutorial I can find is in french! Can you direct me to a good one? Google "CDK and vexus" -- they are the original authors and may have some samples etc. Try ncurses - this is a library which with you may create such GUI environments under console.

CursesSharp (C# NCurses) Updated
Visit chat. Related Hot Network Questions.It is a toolkit for developing " GUI -like" application software that runs under a terminal emulator. It also optimizes screen changes, in order to reduce the latency experienced when using remote shells. As the new version, ncurses is a free-software emulation of the System V Release 4.
The first curses library was developed at the University of California at Berkeley, for a BSD operating system, around to support Roguea text-based adventure game. It originally used the termcap library, which was used in other programs, such as the vi editor. This library was more powerful and instead of using termcap, it used terminfo. AroundPavel Curtis started work on a freeware clone of the Bell Labs curses, named pcurseswhich was maintained by various people through The pcurses library was further improved when Zeyd Ben-Halim took over the development effort in late Subsequent work, through version 1.
Raymondwho added the form and menu libraries written by Juergen Pfeifer. Most ncurses calls can be easily ported to the old curses. System V curses implementations can support BSD curses programs with just a recompilation.
Ncurses can use either terminfo with extensible data or termcap. Other implementations of curses generally use terminfo ; a minority use termcap. Few mytinfo was an older exception  use both. Ncurses is a part of the GNU Project. When the agreement was made to pass on the rights to the FSF, there was a clause that stated: . The Foundation promises that all distribution of the Package, or of any work "based on the Package", that takes place under the control of the Foundation or its agents or assignees, shall be on terms that explicitly and perpetually permit anyone possessing a copy of the work to which the terms apply, and possessing accurate notice of these terms, to redistribute copies of the work to anyone on the same terms.
According to the maintainer Thomas E. Dickey, this precludes relicensing to the GPL in any version, since it would place restrictions on the programs that will be able to link to the libraries. There are hundreds of programs which use ncurses. From Wikipedia, the free encyclopedia. Main article: Curses programming library.
Free and open-source software portal. Retrieved July 9, Raymond September Linux Journal. Dickey December Weinstein April The curses and ncurses new curses libraries go back to 's and 90's and provide an API to create textual user interfaces TUI. If you write a command-line application, you should consider using curses to implement functionality you could not otherwise do with standard console output.
The text editor nano is a good example of a ncurses application. We will look at how to use this library in Python. Read more about curses programming from one of the ncurses authors, Thomas E. Dickey, who also worked on xterm and lynx among other things.
Another author of ncurses was Eric S. There are lots of useful functions in the full API that are not covered here. I strongly encourage you to browse the full documentation.

This tutorial will serve as an introduction to common tasks. If you want to check out a simple finished project that uses Python curses, check out the issh DevDungeon project which creates a menu for choosing SSH connections.
The curses package comes with the Python standard library. In Linux and Mac, the curses dependencies should already be installed so there is no extra steps needed. On Windows, you need to install one special Python package, windows-curses available on PyPI to add support. You can verify everything works by running a Python interpreter and attempting to import curses.
If you do not get any errors, you are in good shape. There are a few important concepts to understand before digging in to the advanced concepts. Some primary things you will need to understand are:. These primary topics will be covered first before we look in to some more common tasks like modifying terminal properties to turn off the cursor, listening for key presses, centering text, and more.
Now that we are confident the curses import worked, we can try to initialize it. When you initialize curses, it creates a new window and clears the screen, displaying your new window. This example will show how to initialize curses and obtain a window to work with. We will call the main window screen. After running this example, you might be surprised by the behavior. It will display a blank screen for one second, and then you will see all of your print statements at the end when you return to the terminal.

The Overflow Bugs vs. Upcoming Events.They abstract away the ANSI escape codes and low level control like tput. They all come with basic terminal control, and some widgets and window managing to create terminal based GUI applications. JCurses seems to be the oldest, and possibly unmaintained. It requires ncurses to be installed, and also a native library. It is available through the Maven Central repository, however, make sure to set up the path for access to the libjcurses.
Charva is also ncurses based and requires a native lib. It seems unlikely that that will work well for all but the simplest UIs, however, at least it offers an easy transition path. Finally, Lanterna seems to be the best maintained, and clearly documented project of the three. It is unique in that is handles all terminal details itself, and does not require external libraries. Furthermore, if launched from an X or similar GUI based environment instead of a terminal, it will create its own GUI window into which it will render the terminal.
The drawback with Lanterna is its rather verbose and involved API. The follow renders a text label with a border:. Lanterna is available through Maven Centralso the following gradle. BLACK ; gui. Show file.Use curses, don't swear
