GNU Screen
GNU Screen is a terminal multiplexer, a software application that can be used to multiplex several virtual consoles, allowing a user to access multiple separate login sessions inside a single terminal window, or detach and reattach sessions from a terminal. It is useful for dealing with multiple programs from a command line interface, and for separating programs from the session of the Unix shell that started the program, particularly so a remote process continues running even when the user is disconnected. Released under the terms of version 3 or later of the GNU General Public License, GNU Screen is free software. Features GNU Screen can be thought of as a text version of graphical window managers, or as a way of putting virtual terminals into any login session. It is a wrapper that allows multiple text programs to run at the same time, and provides features that allow the user to use the programs within a single interface productively. This enables the following features: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Project
The GNU Project () is a free software, mass collaboration project announced by Richard Stallman on September 27, 1983. Its goal is to give computer users freedom and control in their use of their computers and computing devices by collaboratively developing and publishing software that gives everyone the rights to freely run the software, copy and distribute it, study it, and modify it. GNU software grants these rights in its license. In order to ensure that the ''entire'' software of a computer grants its users all freedom rights (use, share, study, modify), even the most fundamental and important part, the operating system (including all its numerous utility programs) needed to be free software. According to its manifesto, the founding goal of the project was to build a free operating system, and if possible, "everything useful that normally comes with a Unix system so that one could get along without any software that is not free." Stallman decided to call this operating sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIGHUP
On POSIX-compliant platforms, SIGHUP ("signal hang up") is a signal sent to a process when its controlling terminal is closed. It was originally designed to notify the process of a serial line drop. SIGHUP is a symbolic constant defined in the header file signal.h. History Access to computer systems for many years consisted of connecting a terminal to a mainframe system via a serial line and the RS-232 protocol. When a system of software interrupts, called signals, was being developed, one of those signals was designated for use on hangup. SIGHUP would be sent to programs when the serial line was dropped, often because the connected user terminated the connection by hanging up the modem. The system would detect the line was dropped via the lost Data Carrier Detect (DCD) signal. Signals have always been a convenient method of inter-process communication (IPC), but in early implementations there were no user-definable signals (such as the later additions of SIGUSR1 and SIGUSR2) t ...

Freshmeat
Freecode, formerly Freshmeat, is a website owned by BIZX, Inc., hosting mainly open-source software for programmers and developers. Among other things, the site also hosted user reviews and discussions. While a majority of the software covered is open source for Unix-like systems, Freecode also covered releases of closed-source, commercial and cross-platform software on and handhelds. Freecode was notable for its age, having started in 1997 as the first web-based aggregator of software releases. The site was renamed from "Freshmeat" to "Freecode" on October 29, 2011, and in September 2012, Dice Holdings acquired the website from Geeknet. Purportedly as a result of low traffic levels, the site is no longer being updated as of June 18, 2014. Because many of the linked software projects are otherwise difficult to find, the site contents have been kept online. After Open Source Initiative co-founder Eric S. Raymond called for a replacement, freshcode.club was created and is accep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISC License
The ISC license is a permissive free software license published by the Internet Software Consortium, now called Internet Systems Consortium (ISC). It is functionally equivalent to the simplified BSD and MIT licenses, but without language deemed unnecessary following the Berne Convention. Originally used for ISC software such as BIND and dig, it has become the preferred license for contributions to OpenBSD and the default license for npm packages. The ISC license is also used for Linux wireless drivers contributed by Qualcomm Atheros. License terms When initially released, the license did not include the term " and/or", which was changed from "and" by ISC in 2007. Paul Vixie stated on the BIND mailing list that the ISC license started using the term "and/or" to avoid controversy similar to the events surrounding the University of Washington's refusal to allow distribution of the Pine email software. OpenBSD license The OpenBSD project began using the ISC license in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tmux
tmux is an open-source terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window. It is useful for running more than one command-line program at the same time. It can also be used to detach processes from their controlling terminals, allowing remote sessions to remain active without being visible. Features tmux includes most features of GNU Screen. It allows users to start a terminal session with clients that are not bound to a specific physical or virtual console; multiple terminal sessions can be created within a single terminal session and then freely rebound from one virtual console to another, and each session can have several connected clients. Some notable tmux features are: * Menus for interactive selection of running sessions, windows or clients * Window can be linked to an arbitrary number of sessions * vi-like or Emacs command mode (with auto completion) for managing tmux * Lack of ...

Byobu (software)
Byobu is an enhancement for the GNU Screen terminal multiplexer or tmux used with the Linux computer operating system that can be used to provide on-screen notification or status, and tabbed multi-window management. It is intended to improve terminal sessions when users connect to remote servers. History Version 1.0, under the name Screen Profiles, came out of discussions at the 2008 Ubuntu Developer Summit about how to simplify the on screen notification of an administrator connected to a server. The project was renamed to Byobu for its 2.0 release, from the Japanese ''byōbu'' folding screen. Byobu 3.0 reworked the build system to use automake and allow for porting to other Unix-like operating systems. Byobu 4.0 introduced screen splitting, reworked the status notification system, and added support for tmux profiles. The most significant change that Byobu 5.0 introduces is a shift from GNU Screen to tmux as the default backend. Originally written for Ubuntu, it has since be ...

X Window System
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interfacethis is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person using a ...

Xpra
xpra, abbreviated from X Persistent Remote Applications, is a set of software utilities that run X clients, typically on a remote host, and direct their display to the local machine without the X clients closing or losing any state in case the network connection between the local machine and the remote host is lost. Xpra differs from standard ''X forwarding'' primarily in allowing disconnection and reconnection without disrupting the forwarded application. It also differs from VNC and similar remote display technologies in being ''rootless'', so applications forwarded by Xpra appear on the local desktop as normal windows managed by the local window manager, rather than being all "trapped in a box together". Xpra also uses a custom protocol that is self-tuning and relatively latency-insensitive, and thus is usable over worse links than standard X. The original inspiration for making Xpra came from the original author's experience of attempting to use various setups based on NX te ...

Screen Sharing
In computing, the term remote desktop refers to a software- or operating system feature that allows a personal computer's desktop environment to be run remotely off of one system (usually a PC, but the concept applies equally to a server or a smartphone), while being displayed on a separate client device. Remote desktop applications have varying features. Some allow attaching to an existing user's session and "remote controlling", either displaying the remote control session or blanking the screen. Taking over a desktop remotely is a form of remote administration. Overview Remote access can also be explained as the remote control of a computer by using another device connected via the internet or another network. This is widely used by many computer manufacturers and large businesses help desks for technical troubleshooting of their customer's problems. Remote desktop software captures the mouse and keyboard inputs from the local computer (client) and sends them to the rem ...

Copy-and-paste
In human–computer interaction and user interface design, cut, copy, and paste are related commands that offer an interprocess communication technique for transferring data through a computer's user interface. The ''cut'' command removes the selected data from its original position, while the ''copy'' command creates a duplicate; in both cases the selected data is kept in temporary storage (the clipboard). The data from the clipboard is later inserted wherever a ''paste'' command is issued. The data remains available to any application supporting the feature, thus allowing easy data transfer between applications. The command names are an interface metaphor based on the physical procedure used in manuscript editing to create a page layout. This interaction technique has close associations with related techniques in graphical user interfaces (GUIs) that use pointing devices such as a computer mouse (by drag and drop, for example). Typically, clipboard support is provided by an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
