Tail (Unix)
is a program available on Unix, Unix-like systems, FreeDOS and MSX-DOS used to display the tail end of a text file or piped data. Implementations The version of bundled in GNU coreutils was written by Paul Rubin, David MacKenzie, Ian Lance Taylor, and Jim Meyering. The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities. The FreeDOS version was developed by M. Aitchison. A command is also part of ASCII's ''MSX-DOS2 Tools'' for MSX-DOS version 2. ''CCZE'' is -like while displaying its output in color. ''pctail'' is similar to CCZE. It is a colorized programmed in Python which tails and colorizes syslog output. ''Inotail'' was an implementation using the inotify Linux kernel interface (introduced in version 2.6.13 in August 2005) to check whether new data is available instead of polling every second, as the original did. However, newer versions of tail also started usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-source Software
Open-source software (OSS) is Software, computer software that is released under a Open-source license, license in which the copyright holder grants users the rights to use, study, change, and Software distribution, distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative, public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to online collaboration, participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2024 estimate of the value of open-source software to firms is $8.8 trillion, as firms would need to spend 3.5 times the amount they currently do without the use of open source software. Open-source code can be used for studying and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Program
A computer program is a sequence or set of instructions in a programming language for a computer to Execution (computing), execute. It is one component of software, which also includes software documentation, documentation and other intangible components. A ''computer program'' in its human-readable form is called source code. Source code needs another computer program to Execution (computing), execute because computers can only execute their native machine instructions. Therefore, source code may be Translator (computing), translated to machine instructions using a compiler written for the language. (Assembly language programs are translated using an Assembler (computing), assembler.) The resulting file is called an executable. Alternatively, source code may execute within an interpreter (computing), interpreter written for the language. If the executable is requested for execution, then the operating system Loader (computing), loads it into Random-access memory, memory and ...

Watch (command)
watch is a command-line tool, part of the Linux and packages, that runs the specified command repeatedly and displays the results on standard output so the user can watch it change over time. By default, the command is run every two seconds, although this is adjustable with the -n ''secs'' argument. Since the command is passed to sh -c, it may be necessary to encase it in quotes for it to run correctly. Syntax watch 'options''''command'' 'command options'' Example watch " ps -e , grep php" This will generate a list of processes every two seconds, filter for all lines that contain the word "php", and display the results on the screen. The output might look something like this: Every 2s: ps -e , grep php Tue Jan 30 14:56:33 2007 reconst 30028 0.0 0.0 7044 2596 ?

Inotify
inotify (inode notify) is a Linux kernel subsystem created by John McCutchan, which monitors changes to the filesystem, and reports those changes to applications. It can be used to automatically update directory views, reload configuration files, log changes, backup, synchronize, and upload. The ''inotifywait'' and ''inotifywatch'' commands (maintained by Eric Curtin as part of the inotify-tools project) allow using the inotify subsystem from the command line. One major use is in desktop search utilities like Beagle, where its functionality permits reindexing of changed files without scanning the filesystem for changes every few minutes, which would be very inefficient. inotify replaced an earlier facility, dnotify, which had similar goals. Inotify was merged into the Linux kernel mainline in kernel version 2.6.13, released on August 29, 2005; later kernel versions included further improvements. The required library interfaces were added into the GNU C Library (glibc) in it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Python (programming Language)
Python is a high-level programming language, high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is type system#DYNAMIC, dynamically type-checked and garbage collection (computer science), garbage-collected. It supports multiple programming paradigms, including structured programming, structured (particularly procedural programming, 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), ABC programming language, and he first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000. Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions. Python 2.7.18, released in 2020, was the last release of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ASCII Corporation
was a Japanese publishing company based in Chiyoda, Tokyo. It became a subsidiary of Kadokawa Group Holdings in 2004, and merged with another Kadokawa subsidiary MediaWorks on April 1, 2008, becoming ASCII Media Works. The company published '' Monthly ASCII'' as the main publication. ASCII is best known for creating the '' Derby Stallion'' video game series, the MSX computer, and the '' RPG Maker'' line of programming software. History 1977–1990: Founding and first projects ASCII was founded in 1977 by Kazuhiko Nishi, Akio Gunji and Keiichiro Tsukamoto. The name was taken from the ASCII code that was referred to a computer character set. Originally the publisher of a magazine with the same name, ''ASCII'', talks between Bill Gates and Nishi led to the creation of Microsoft's first overseas sales office, ASCII Microsoft, in 1978.Quote from Bill Gates' ''The Road Ahead'', found in In 1980, ASCII made 1.2 billion yen of sales from licensing Microsoft BASIC. It was 40 percen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porting
In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program (meant for such execution) was originally designed for (e.g., different CPU, operating system, or third party library). The term is also used when software/hardware is changed to make them usable in different environments. Software is ''portable'' when the cost of porting it to a new platform is significantly less than the cost of writing it from scratch. The lower the cost of porting software relative to its implementation cost, the more portable it is said to be. This is distinct from cross-platform software, which is designed from the ground up without any single " native" platform. Etymology The term "port" is derived from the Latin '' portāre'', meaning "to carry". When code is not compatible with a particular operating system or architecture, the code must be "carried" to ...

Windows API
The Windows API, informally WinAPI, is the foundational application programming interface (API) that allows a computer program to access the features of the Microsoft Windows operating system in which the program is running. Programs can access API functionality via shared-library technologies or via system-file access. Each major version of the Windows API has a distinct name that identifies a compatibility aspect of that version. For example, Win32 is the major version of Windows API that runs on 32-bit systems. The name, Windows API, collectively refers to all versions of this capability of Windows. Microsoft provides developer support via a software development kit, Microsoft Windows SDK, which includes documentation and tools for building software based on the Windows API. Services This section lists notable services provided by the Windows API. Base Services Base services include features such as the file system, devices, processes, threads, and error handl ...

Native (computing)
Native describes a computing system as operating directly with an underlying technology; with no intervening communication or translation layers. Native software Native software is built to be executed directly by processors that implement a compatible instruction set. A program that runs natively on one platform is runnable on another platform via an emulator if an emulator is available and, generally, with significant runtime speed degradation. For example, games for a Game Boy (typically distributed as a cartridge), generally run natively on a Game Boy which is relatively incompatible with other computer platforms. To run such a game on another processor, software that emulates the Game Boy hardware is required. Cross-platform software can run on multiple processors although possibly requiring it to be re-built for different target systems. Native API A native application programming interface (API) provides direct access to an underlying technology. For example, ...

UnxUtils
UnxUtils is a collection of utility programs that provide popular Unix-based shell commands ported from GNU implementations as native Windows programs that depend only on Win32 and the Microsoft C- runtime ( msvcrt.dll). The collection was last updated externally on April 15, 2003, by Karl M. Syring. , the most recent release was an open-source project at SourceForge, with the latest binary release in March, 2007 (though the files are dated 2000). The independent distribution included a main zip archive (UnxUtils.zip, 3,365,638 bytes) complemented by more recent updates (UnxUpdates.zip, 878,847 bytes, brought some binaries up to year 2003), but the SourceForge project has no UnxUpdates.zip package. An alternative collection of Unix-based utilities for Windows is GnuWin32. It has later versions of many programs, but requires supporting files (e.g. DLLs). Supported commands include: * agrep *ansi2knr * basename * bc *bison *bunzip2 *bzip2 *bzip2recover * cat *chgrp *chm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
