The next few examples demonstrate additional features and show the expanded wiki markup text that this pipe-trick process generates, which in turn generates the results in the page display. Since Wikipedia is case-insensitive in regard to the first character of the target title, it is possible to use the pipe trick for upper- or lowercase words ...
In many programming languages, the vertical bar is used to designate the logic operation or, either bitwise or or logical or. Specifically, in C and other languages following C syntax conventions, such as C++ , Perl , Java and C# , a | b denotes a bitwise or ; whereas a double vertical bar a || b denotes a ( short-circuited ) logical or .
the wording of the exact link title does not fit in context (see here as an example), or; there are multiple meanings of the word (see "Mercury" example on the Disambiguation page). The pipe ("|") character is also known as a vertical bar. There are two ways to create the pipe ("|") character: using the keyboard or choosing from a list of symbols.
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.. In POSIX extended regular expressions, there are 14 metacharacters that must be escaped — preceded by a backslash (\) — in order to drop their special meaning and be treated literally inside an expression: opening and closing square brackets ...
In Python, the set-builder's braces are replaced with square brackets, parentheses, or curly braces, giving list, generator, and set objects, respectively. Python uses an English-based syntax. Haskell replaces the set-builder's braces with square brackets and uses symbols, including the standard set-builder vertical bar.
[2]: 113 [5] The vertical bar (also referred to as pipe) and space are also sometimes used. [2]: 113 Column headers are sometimes included as the first line, and each subsequent line is a row of data. The lines are separated by newlines. For example, the following fields in each record are delimited by commas, and each record by newlines:
Standard output is a stream to which a program writes its output data. The program requests data transfer with the write operation. Not all programs generate output. For example, the file rename command (variously called mv, move, or ren) is silent on success. Unless redirected, standard output is inherited from the parent process.
Use a vertical bar "|" (the "pipe" symbol) to create a link which appears as a term other than the name of the target page. Links of this kind are said to be " piped ". The first term inside the brackets is the title of the page you would be taken to (the link target), and anything after the vertical bar is what the link looks like for the ...
