String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.

A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings , or for input validation .
Greed, in regular expression context, describes the number of characters which will be matched (often also stated as "consumed") by a variable length portion of a regular expression – a token or group followed by a quantifier, which specifies a number (or range of numbers) of tokens. If the portion of the regular expression is "greedy", it ...
Replace text with last edit — If page saving fails, for example because of a timeout, use this option when the page has reloaded to restore the edit box to the text in it prior to saving. The purpose of this option is to be able to retrieve manually added text in such situations; if you use this option you must manually check for any edit ...
Sed regular expressions, particularly those using the "s" operator, are much similar to Perl (sed is a predecessor to Perl). The default delimiter is "/", but any delimiter can be used; the default is s / regexp / replacement /, but s: regexp: replacement: is also a valid form. For example, to match a "pub" directory (as in the Perl example ...
Substitution commands are of the form s/regexp/replacement/, where regexp is a regular expression, for parsing input, and replacement is a simple template for output, either literal text, or a format string containing the characters & for "entire match" or the special escape sequences \1 through \9 for the nth sub-expression.
