Friendly Interactive Shell
fish is a Unix shell with a focus on interactivity and usability. Fish is designed to give the user features by default, rather than by configuration. Fish is considered an exotic shell since it does not rigorously adhere to POSIX shell standards, at the discretion of the maintainers. Highlights Fish has " search as you type" automatic suggestions based on history and current directory. This is essentially like Bash's history search, but because it is always on instead of being a separate mode, the user gets continuous feedback while writing the command line, and can select suggestions with the arrow keys, or as in Bash, press for a tab completion instead. Tab-completion is feature-rich, expanding file paths (with wildcards and brace expansion), variables, and many command specific completions. Command-specific completions, including options with descriptions, can to some extent be generated from the commands' man pages. Fish prefers features as commands rather than syntax ...

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 ...

Control Flow
In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an ''imperative programming'' language from a '' declarative programming'' language. Within an imperative programming language, a ''control flow statement'' is a statement that results in a choice being made as to which of two or more paths to follow. For non-strict functional languages, functions and language constructs exist to achieve the same result, but they are usually not termed control flow statements. A set of statements is in turn generally structured as a block, which in addition to grouping, also defines a lexical scope. Interrupts and signals are low-level mechanisms that can alter the flow of control in a way similar to a subroutine, but usually occur as a response to some external stimulus or event (that can occur asynchronously), ...

Gitorious
Gitorious was a free and open source web application for hosting collaborative free and open-source software development projects using Git revision control. Although it was freely available to be downloaded and installed, it was written primarily as the basis for the Gitorious shared web hosting service at ''gitorious.org'', until it was acquired by GitLab in 2015. According to the Git User's Survey, Gitorious was the second most popular hosting service for Git in 2011, with 11.7% of respondents indicating they used it, behind 87.5% using GitHub. On 3 March 2015, Gitorious was acquired by GitLab, who announced service through gitorious.org would be discontinued on 1 June 2015 and encouraged Gitorious users to make use of its import tools to migrate projects to GitLab. Features and constraints In addition to source code hosting, Gitorious provided projects with wikis, a web interface for merge requests and code reviews, and activity timelines for projects and developers.

String Literal
A string literal (computer programming), literal or anonymous string is a String (computer science), string value in the source code of a computer program. Modern Computer programming, programming languages commonly use a quoted sequence of characters, formally "#Bracketed delimiters, bracketed delimiters", as in x = "foo", where "foo" is a string Literal (computer programming), literal with value foo. Methods such as #Escape sequences, escape sequences can be used to avoid the problem of #Delimiter collision, delimiter collision (issues with brackets) and allow the delimiters to be embedded in a string. There are many alternate notations for specifying string literals especially in complicated cases. The exact notation depends on the programming language in question. Nevertheless, there are general guidelines that most modern programming languages follow. Syntax Bracketed delimiters Most modern programming languages use delimiter#Bracket delimiters, bracket delimiters (also ba ...

Glob (programming)
In computer programming, glob () patterns specify sets of filenames with wildcard characters. For example, the Unix Bash shell command mv *.txt textfiles/ moves (mv) all files with names ending in .txt from the current directory to the directory textfiles. Here, * is a wildcard standing for "any string of characters except /" and *.txt is a glob pattern. The other common wildcard is the question mark (?), which stands for one character. For example, mv ?.txt shorttextfiles/ will move all files named with a single character followed by .txt from the current directory to directory shorttextfiles, while ??.txt would match all files whose name consists of 2 characters followed by .txt. In addition to matching filenames, globs are also used widely for matching arbitrary strings ( wildcard matching). In this capacity a common interface is fnmatch. Origin The glob command, short for ''global'', originates in the earliest versions of Bell Labs' Unix. The command interpreters of the ear ...

Command History
Command history is a feature in many operating system shells, computer algebra programs, and other software that allows the user to recall, edit and rerun previous commands. Command line history was added to Unix in Bill Joy's C shell of 1978; Joy took inspiration from an earlier implementation in Interlisp. It quickly became popular because it made the C shell fast and easy to use. History has since become a standard feature in other shells, including ksh, Bash and Microsoft's cmd.exe. History addressed two important scenarios: # Executing the same command or a short sequence of commands over and over. An example might be a developer frequently compiling and running a program. # Correcting mistakes or rerunning a command with only a small modification. In Joy's original C shell, the user could refer to a previous command by typing an exclamation, !, followed by additional characters to specify a particular command, only certain words, or to edit it in some way before pa ...

Terminfo
Terminfo is a library and database that enables programs to use display terminals in a device-independent manner. Mary Ann Horton implemented the first terminfo library in 1981–1982 as an improvement over termcap. The improvements include * faster access to stored terminal descriptions, * longer, more understandable names for terminal capabilities and * general expression evaluation for strings sent to the terminal. Terminfo was included with UNIX System V Release 2 and soon became the preferred form of terminal descriptions in System V, rather than termcap (which BSD continued to use). This was imitated in pcurses in 1982–1984 by Pavel Curtis, and was available on other UNIX implementations, adapting or incorporating fixes from Mary Horton. For more information, refer to the posting on the comp.sources.unix newsgroup from December 1986. A terminfo database can describe the capabilities of hundreds of different display terminals. This allows external programs to be able to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Terminal
A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. The teletype was an example of an early-day hard-copy terminal and predated the use of a computer screen by decades. Early terminals were inexpensive devices but very slow compared to punched cards or paper tape for input, yet as the technology improved and video displays were introduced, terminals pushed these older forms of interaction from the industry. A related development was time-sharing systems, which evolved in parallel and made up for any inefficiencies in the user's typing ability with the ability to support multiple users on the same machine, each at their own terminal or terminals. The function of a terminal is typically confined to transcription and input of data; a device with significant local, programmable data-processing capability may be called a "smart terminal" or fat client. A ter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clipboard (software)
The clipboard is a buffer that some operating systems provide for short-term storage and transfer within and between application programs. The clipboard is usually temporary and unnamed, and its contents reside in the computer's RAM. The clipboard provides an application programming interface by which programs can specify cut, copy and paste operations. It is left to the program to define methods for the user to command these operations, which may include keybindings and menu selections. When an element is copied or cut, the clipboard must store enough information to enable a sensible result no matter where the element is pasted. Application programs may extend the clipboard functions that the operating system provides. A clipboard manager may give the user additional control over the clipboard. Specific clipboard semantics vary among operating systems, can also vary between versions of the same system, and can sometimes be changed by programs and by user preferences. Windows, Li ...
