Basename
basename is a shell command for extracting the last name of a file path. The command was introduced in X/Open Portability Guidelines issue 2 of 1987. It was inherited into the first version of POSIX and the Single Unix Specification. It first appeared in 4.4BSD. The version in GNU Core Utilities was written by David MacKenzie. The command is available for Windows as part of the GnuWin32 project and UnxUtils. Use The Single UNIX Specification The Single UNIX Specification (SUS) is a standard for computer operating systems, compliance with which is required to qualify for using the "UNIX" trademark. The standard specifies programming interfaces for the C language, a command-line shell, ... is: . The required argument, path, is a file path string. The second argument, which is optional, is text to remove from the end of the last name if it ends with the text. Examples The command reports the last part of a path ignoring any trailing slashes. $ basename /home/jsmith/base.wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
File Path
A path (or filepath, file path, pathname, or similar) is a text string that uniquely specifies an item in a hierarchical file system. Generally, a path is composed of directory names, special directory specifiers and optionally a filename, separated by delimiting text. The delimiter varies by operating system and in theory can be anything, but popular, modern systems use slash , backslash , or colon . A path can be either relative or absolute. A relative path includes information that is relative to a particular directory whereas an absolute path indicates a location relative to the system root directory, and therefore, does not depends on context like a relative path does. Often, a relative path is relative to the working directory. For example, in command , is a relative path to the file with that name in the working directory. Paths are used extensively in computer science to represent the directory/file relationships common in modern operating systems and are essential i ...

Coreutils
The GNU Core Utilities or coreutils is a collection of GNU software that implements many standard, Unix-based shell commands. The utilities generally provide POSIX compliant interface when the environment variable is set, but otherwise offers a superset to the standard interface. For example, the utilities support long options and options after parameters. This environment variable enables a different functionality in BSD. Similar collections are available in the FOSS ecosystem, with a slightly different scope and focus (less functionality), or license. For example, BusyBox which is licensed under GPL-2.0-only, and Toybox which is licensed under 0BSD. Commands The commands implemented by coreutils are listed below. Throughout this article and customary for Unix-based systems, the term ''file'' refers to all file system items including regular files and special files such as directories.

POSIX
The Portable Operating System Interface (POSIX; ) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. POSIX defines application programming interfaces (APIs), along with command line shells and utility interfaces, for software compatibility (portability) with variants of Unix and other operating systems. POSIX is also a trademark of the IEEE. POSIX is intended to be used by both application and system developers. As of POSIX 2024, the standard is aligned with the C17 language standard. Name Originally, the name "POSIX" referred to IEEE Std 1003.1-1988, released in 1988. The family of POSIX standards is formally designated as IEEE 1003 and the ISO/IEC standard number is ISO/ IEC 9945. The standards emerged from a project that began in 1984 building on work from related activity in the ''/usr/group'' association. Richard Stallman suggested the name ''POSIX'' to the IEEE instead of the former ''IEEE-IX''. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plan 9 Commands
A plan is typically any diagram or list of steps with details of timing and resources, used to achieve an objective to do something. It is commonly understood as a temporal set of intended actions through which one expects to achieve a goal. For spatial or planar topologic or topographic sets see map. Plans can be formal or informal: * Structured and formal plans, used by multiple people, are more likely to occur in projects, diplomacy, careers, economic development, military campaigns, combat, sports, games, or in the conduct of other business. In most cases, the absence of a well-laid plan can have adverse effects: for example, a non-robust project plan can cost the organization time and money. * Informal or ad hoc plans are created by individuals in all of their pursuits. The most popular ways to describe plans are by their breadth, time frame, and specificity; however, these planning classifications are not independent of one another. For instance, there is a close ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix SUS2008 Utilities
Unix (, ; trademarked as 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. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems (SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows Un ...

Single UNIX Specification
The Single UNIX Specification (SUS) is a standard for computer operating systems, compliance with which is required to qualify for using the "UNIX" trademark. The standard specifies programming interfaces for the C language, a command-line shell, and user commands. The core specifications of the SUS known as ''Base Specifications'' are developed and maintained by the Austin Group, which is a joint working group of IEEE, ISO/IEC JTC 1/SC 22/WG 15 and The Open Group. If an operating system is submitted to The Open Group for certification and passes conformance tests, then it is deemed to be compliant with a UNIX standard such as UNIX 98 or UNIX 03. Very few BSD and Linux-based operating systems are submitted for compliance with the Single UNIX Specification, although system developers generally aim for compliance with POSIX standards, which form the core of the Single UNIX Specification. The latest SUS consists of two parts: the ''base specifications'' technically iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft.
