Rename (computing)
In computing, rename refers to the altering of a name of a file. This can be done manually by using a shell command such as ren (command), ren or mv (Unix), mv, or by using batch renaming software that can automate the renaming process. Implementations The C standard library provides a function called ''rename'' which does this action. In POSIX, which is extended from the C standard, the ''rename'' function will fail if the old and new names are on different mounted file systems. In SQL, renames are performed by using the CHANGE specification in Alter (SQL), ALTER TABLE statements. Atomic rename In POSIX, a successful call to ''rename'' is guaranteed to have been Atomic operation, atomic from the point of view of the current host (i.e., another program would only see the file with the old name or the file with the new name, not both or neither of them). This aspect is often used during a file save operation to avoid any possibility of the file contents being lost if the save opera ...

Ren (command)
ren (or rename) is a shell command for renaming a file and in some implementations (such as AmigaDOS) a directory. Some shells with also provide a move command that provides for moving between directories. On systems that do not support a move command (such as MS-DOS older than 6.00), the user could copy a file to a new destination and then delete the original file. In DOSBox, ren can move files. The command is in various shells such as COMMAND.COM, Command Prompt, 4DOS, 4NT and PowerShell. In MS-DOS, the command is available in versions 1 and later. In PowerShell, ren is a predefined alias for the Rename-Item Cmdlet which serves the same essential purpose. Similar commands are available in many operating systems. The command is available in the CP/M, MP/M, Cromemco DOS, TRIPOS, OS/2, ReactOS, SymbOS, and DexOS. Multics includes a rename command to rename a directory entry; which could be contracted to rn. A command which in some cases can be contracted to ren i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mv (Unix)
mv is a shell command for renaming and moving files and directories. If both items are on the same file system, the command renames; otherwise items are copied to the destination and the old items are removed (more specifically unlinked). To move between two directories, the user must have write permission for both because the command modifies the content of both. For a rename, an item's timestamp is not modified. On Unix implementations derived from AT&T Unix, cp, ln and mv are implemented as a single program with hard-linked binaries. History Multics provided a file move/rename command named . A version with the contracted name appeared in Version 1 Unix and became part of the X/Open Portability Guide issue 2 of 1987. The version in GNU Core Utilities was written by Mike Parker, David MacKenzie, and Jim Meyering. The command is available in Windows via UnxUtils. The command was ported to IBM i. Options Most implementations support: * -i interactive; the comma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batch Renaming
Batch renaming is a form of batch processing used to rename multiple computer files and folders in an automated fashion, in order to save time and reduce the amount of work involved. Some sort of software is required to do this. Such software can be more or less advanced, but most have the same basic functions. Batch renaming can also be referred to as 'mass file renaming', rename 'en masse' and 'bulk renaming'. Common functions Most batch renamers share a basic set of functions to manipulate the filenames: * Find a string within the filename and replace it with another, or remove it. * Setting the capitalization of the letters in the filenames. * Extracting information from the files, such as Mp3 ID3 tags, and putting it in the filename. * Add a number sequence (001,002,003,...) to a list of files. * Use a text file as a source for new file names. Some batch rename software can do more than just renaming filenames. Features include changing the dates of files and changing the ...

C Standard Library
The C standard library, sometimes referred to as libc, is the standard library for the C (programming language), C programming language, as specified in the ISO C standard.International Organization for Standardization, ISO/International Electrotechnical Commission, IEC (2018). ''C17 (C standard revision), ISO/IEC 9899:2018(E): Programming Languages - C §7'' Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. Since ANSI C was adopted by the International Organization for Standardization, the C standard library is also called the ISO C library. The C standard library provides macro (computer science), macros, Data type, type definitions and Function (computer programming), functions for tasks such as character string (computer science), string manipulation, mathematical computation, input/output processing, memory management, and input/output.

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] |
Alter (SQL)
In the context of SQL, data definition or data description language (DDL) is a syntax for creating and modifying database objects such as tables, indices, and users. DDL statements are similar to a computer programming language for defining data structures, especially database schemas. Common examples of DDL statements include CREATE, ALTER, and DROP. If you see a .ddl file, that means the file contains a statement to create a table. Oracle SQL Developer contains the ability to export from an ERD generated with Data Modeler to either a .sql file or a .ddl file. History The concept of the data definition language and its name was first introduced in relation to the Codasyl database model, where the schema of the database was written in a language syntax describing the records, fields, and sets of the user data model. Later it was used to refer to a subset of Structured Query Language (SQL) for declaring tables, columns, data types and constraints. SQL-92 introduced a ...

Atomic Operation
In concurrent programming, an operation (or set of operations) is linearizable if it consists of an ordered list of Execution (computing), invocation and response Event (computing), events, that may be extended by adding response events such that: # The extended list can be re-expressed as a sequential history (is serializability, serializable). # That sequential history is a subset of the original unextended list. Informally, this means that the unmodified list of events is linearizable if and only if its invocations were serializable, but some of the responses of the serial schedule have yet to return. In a concurrent system, processes can access a shared Object (computer science), object at the same time. Because multiple processes are accessing a single object, a situation may arise in which while one process is accessing the object, another process changes its contents. Making a system linearizable is one solution to this problem. In a linearizable system, although operat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows (OS)
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a Server (computing), server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to Original equipment manufacturer, third-party hardware manufacturers who sell products Software bundles, bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families ...

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 ...
