TkDesk, released under the GNU GPL, is a graphical file manager for the X Window System, a standard component of Unix and Unix-like systems. TkDesk saw its last update in 2004.
It is highly configurable, since it is based upon Tcl and Tk.
Cygwin is a Unix-like environment and command-line interface for Microsoft Windows. Cygwin's purpose is expressed in its motto: "Get that Linux feeling – on Windows".
In computing, the Executable and Linkable Format, is a common standard file format for executable files, object code, shared libraries, and core dumps. First published in the specification for the application binary interface (ABI) of the Unix operating system version named System V Release 4 (SVR4), and later in the Tool Interface Standard, it was quickly accepted among different vendors of Unix systems. In 1999, it was chosen as the standard binary file format for Unix and Unix-like systems on x86 processors by the 86open project.
A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script which sets up the environment, runs the program, and does any necessary cleanup or logging, is called a wrapper.
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts.
grep is a command-line utility for searching plain-text data sets for lines that match a regular expression. Its name comes from the ed command
g/re/p, which has the same effect.
grep was originally developed for the Unix operating system, but later available for all Unix-like systems and some others such as OS-9.
The Open Group is a global consortium that seeks to "enable the achievement of business objectives" by developing "open, vendor-neutral technology standards and certifications." It has over 840 member organizations and provides a number of services, including strategy, management, innovation and research, standards, certification, and test development. It was established in 1996 when X/Open merged with the Open Software Foundation.
A man page is a form of software documentation usually found on a Unix or Unix-like operating system. Topics covered include computer programs, formal standards and conventions, and even abstract concepts. A user may invoke a man page by issuing the
The year 2038 problem is a time formatting bug in computer systems with representing times after 03:14:07 UTC on 19 January 2038.
In some operating systems, the null device is a device file that discards all data written to it but reports that the write operation succeeded. This device is called
/dev/null on Unix and Unix-like systems,
NUL on CP/M and DOS,
nul on OS/2 and newer Windows systems,
NIL: on Amiga operating systems, and
NL: on OpenVMS. In Windows Powershell, the equivalent is
$null. It provides no data to any process that reads from it, yielding EOF immediately. In IBM operating systems DOS/360 and successors and also in OS/360 and successors such files would be assigned in JCL to
UnixWare is a Unix operating system. It was originally released by Univel, a jointly owned venture of AT&T's Unix System Laboratories (USL) and Novell. It was then taken over by Novell. Via Santa Cruz Operation (SCO), it went on to Caldera Systems, Caldera International, and The SCO Group before it was sold to UnXis. UnixWare is typically deployed as a server rather than a desktop. Binary distributions of UnixWare are available for x86 architecture computers. UnixWare is primarily marketed as a server operating system.
Clam AntiVirus (ClamAV) is a free software, cross-platform antimalware toolkit able to detect many types of malware, including viruses. It was developed for Unix and has third party versions available for AIX, BSD, HP-UX, Linux, macOS, OpenVMS, OSF (Tru64) and Solaris. As of version 0.97.5, ClamAV builds and runs on Microsoft Windows. Both ClamAV and its updates are made available free of charge. One of its main uses is on mail servers as a server-side email virus scanner.
Unix time is a date and time representation widely used in computing. It measures time by the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970, the Unix epoch, without adjustments made due to leap seconds. In modern computing, values are sometimes stored with higher granularity, such as microseconds or nanoseconds.
sudo is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. It originally stood for "superuser do", as that was all it did, and it is its most common usage; however, the official Sudo project page lists it as "su 'do' ". The current Linux manual pages for su define it as "substitute user", making the correct meaning of sudo "substitute user, do", because sudo can run a command as other users as well.
The following tables compare general and technical information between a number of notable IRC client programs which have been discussed in independent, reliable prior published sources.
Tk is a cross-platform widget toolkit that provides a library of basic elements of GUI widgets for building a graphical user interface (GUI) in many programming languages. It is free and open-source software released under a BSD-style software license.
wish is a Tcl interpreter extended with Tk commands, available for Unix-like operating systems supporting the X Window System, as well as macOS, Microsoft Windows, and Android. It provides developers the ability to create GUI widgets using the Tk toolkit and the Tcl programming language.
Unix is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
A command-line interface (CLI) is a means of interacting with a device or computer program with commands from a user or client, and responses from the device or program, in the form of lines of text. 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.
tkWWW is an early, now discontinued web browser and WYSIWYG HTML editor written by Joseph Wang at MIT as part of Project Athena and the Globewide Network Academy project. The browser was based on the Tcl language and the Tk (toolkit) extension but did not achieve broad user-acceptance or market share, although it was included in many Linux distributions by default. Joseph Wang wanted tkWWW to become a replacement for r r n and to become a "swiss army knife" of networked computing.
Tcl is a high-level, general-purpose, interpreted, dynamic programming language. It was designed with the goal of being very simple but powerful. Tcl casts everything into the mold of a command, even programming constructs like variable assignment and procedure definition. Tcl supports multiple programming paradigms, including object-oriented, imperative and functional programming or procedural styles.
