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 ...

Bourne Shell
The Bourne shell (sh) is a Shell (computing), shell Command-line interface#Command-line interpreter, command-line interpreter for computer operating systems. The Bourne shell was the default Unix shell, shell for Version 7 Unix. Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell—even when other shells are used by most users. Developed by Stephen R. Bourne, Stephen Bourne at Bell Labs, it was a replacement for the Thompson shell, whose executable file had the same name—sh. It was released in 1979 in the Version 7 Unix release distributed to colleges and universities. Although it is used as an interactive command interpreter, it was also intended as a scripting language and contains most of the features that are commonly considered to produce structured programs. It gained popularity with the publication of ''The Unix Programming Environment'' by Brian Kernighan and Rob Pike—the first commercial ...

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run multipl ...

Command-line Interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables. Such access was first provided by computer terminals starting in the mid-1960s. This provided an interactive environment not available with punched cards or other input methods. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and use a command line. Alternatives to the command-line interface include text-based user interface menus (for example, IBM AIX SMIT), keyboard shortcuts, and various desktop metaphors centered on the pointer (usual ...

GPLv3
The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses that guarantee end users the four freedoms to run, study, share, and modify the software. The license was the first copyleft for general use and was originally written by the founder of the Free Software Foundation (FSF), Richard Stallman, for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. These GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the Lesser General Public License and even further distinct from the more widely used permissive software licenses BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software domain. Prominent free software programs licensed under the GPL include the Linux kernel an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Terminal Multiplexer
A terminal multiplexer is a software application that can be used to multiplex several separate pseudoterminal-based login sessions inside a single terminal display, terminal emulator window, PC/workstation system console, or remote login session, or to 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. Features A terminal multiplexer can be thought of as a text version of graphical window managers, or as a way of putting attach virtual terminals to 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. ; Persistence: Similar to Virtual Network Computing, many terminal multiplexers allow the us ...

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 ...

Computer Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and th ...

Byōbu
are Japanese folding screens made from several joined panels, bearing decorative painting and calligraphy, used to separate interiors and enclose private spaces, among other uses. History are thought to have originated in Han dynasty China and are thought to have been imported to Japan in the 7th or 8th century (Nara period). The oldest surviving produced in Japan, the , produced in the 8th century, is kept in the Shōsōin Treasure Repository. Nara-period retained their original form of a single, free-standing, legged panel. In the 8th century, multi-paneled made their appearance, and were used as furnishings in the imperial court, mainly in important ceremonies. The six-paneled were the most common in the Nara period, and were covered in silk and connected with leather or silk cords. The painting on each panel was framed by a silk brocade, and the panel was bound with a wood frame. By the Heian period (794–1185), particularly by the 9th century, were indispens ...

Automake
In software development, GNU Automake is a programming tool to automate parts of the compilation process. It eases usual compilation problems. For example, it points to needed dependencies. It automatically generates one or more ''Makefile.in'' from files called ''Makefile.am''. Each ''Makefile.am'' contains, among other things, useful variable definitions for the compiled software, such as compiler and linker flags, dependencies and their versions, etc. The generated "''Makefile.in''"s are portable and compliant with the Makefile conventions in the GNU Coding Standards, and may be used by configure scripts to generate a working Makefile. The Free Software Foundation maintains as one of the GNU programs, and as part of the GNU build system. It is used to build several GNU applications and libraries, such as GTK, as well as non-GNU software such as XCircuit. Process Automake aims to allow the programmer to write a makefile in a higher-level language, rather than having t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
