Metacharacter, the Glossary
A metacharacter is a character that has a special meaning to a computer program, such as a shell interpreter or a regular expression (regex) engine.[1]

- Pattern matching
Ampersand
The ampersand, also known as the and sign, is the logogram, representing the conjunction "and".
See Metacharacter and Ampersand
Backtick
The backtick is a typographical mark used mainly in computing.
See Metacharacter and Backtick
Character encodings in HTML
While Hypertext Markup Language (HTML) has been in use since 1991, HTML 4.0 from December 1997 was the first standardized version where international characters were given reasonably complete treatment.
See Metacharacter and Character encodings in HTML
Cmd.exe
Command Prompt, also known as cmd.exe or cmd, is the default command-line interpreter for the OS/2, eComStation, ArcaOS, Microsoft Windows (Windows NT family and Windows CE family), and ReactOS operating systems.
Command substitution
In computing, command substitution is a facility that allows a command to be run and its output to be pasted back on the command line as arguments to another command. Metacharacter and command substitution are programming language topics.
See Metacharacter and Command substitution
Delimiter
A delimiter is a sequence of one or more characters for specifying the boundary between separate, independent regions in plain text, mathematical expressions or other data streams. Metacharacter and delimiter are Pattern matching.
See Metacharacter and Delimiter
Escape character
In computing and telecommunication, an escape character is a character that invokes an alternative interpretation on the following characters in a character sequence. Metacharacter and escape character are Pattern matching.
See Metacharacter and Escape character
Greater-than sign
The greater-than sign is a mathematical symbol that denotes an inequality between two values.
See Metacharacter and Greater-than sign
HTML
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser.
Less-than sign
The less-than sign is a mathematical symbol that denotes an inequality between two values.
See Metacharacter and Less-than sign
Markup language
A markup language is a text-encoding system which specifies the structure and formatting of a document and potentially the relationship between its parts. Metacharacter and markup language are formal languages.
See Metacharacter and Markup language
Microsoft
Microsoft Corporation is an American multinational corporation and technology company headquartered in Redmond, Washington.
See Metacharacter and Microsoft
MS-DOS
MS-DOS (acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft.
Percent sign
The percent sign (sometimes per cent sign in British English) is the symbol used to indicate a percentage, a number or ratio as a fraction of 100.
See Metacharacter and Percent sign
Perl Compatible Regular Expressions
Perl Compatible Regular Expressions (PCRE) is a library written in C, which implements a regular expression engine, inspired by the capabilities of the Perl programming language. Metacharacter and Perl Compatible Regular Expressions are Pattern matching.
See Metacharacter and Perl Compatible Regular Expressions
Printf
printf is a C standard library function that formats text and writes it to standard output.
Programming language
A programming language is a system of notation for writing computer programs.
See Metacharacter and Programming language
Quotation mark
Quotation marks are punctuation marks used in pairs in various writing systems to identify direct speech, a quotation, or a phrase.
See Metacharacter and Quotation mark
Redirection (computing)
In computing, redirection is a form of interprocess communication, and is a function common to most command-line interpreters, including the various Unix shells that can redirect standard streams to user-specified locations.
See Metacharacter and Redirection (computing)
Semicolon
The semicolon (or semi-colon) is a symbol commonly used as orthographic punctuation.
See Metacharacter and Semicolon
SQL
Structured Query Language (SQL) (pronounced S-Q-L; historically "sequel") is a domain-specific language used to manage data, especially in a relational database management system (RDBMS).
String (computer science)
In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. Metacharacter and string (computer science) are formal languages.
See Metacharacter and String (computer science)
The Open Group
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 900+ member organizations and provides a number of services, including strategy, management, innovation and research, standards, certification, and test development.
See Metacharacter and The Open Group
Underscore
An underscore or underline is a line drawn under a segment of text.
See Metacharacter and Underscore
Unix shell
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems.
See Metacharacter and Unix shell
Wildcard character
In software, a wildcard character is a kind of placeholder represented by a single character, such as an asterisk, which can be interpreted as a number of literal characters or an empty string. Metacharacter and wildcard character are Pattern matching.
See Metacharacter and Wildcard character
World Wide Web Consortium
The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web.
See Metacharacter and World Wide Web Consortium
XML
Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing arbitrary data.
