grep is a command-line utility for searching plaintext datasets for lines that match a regular expression. Its name comes from the ed command g/re/p (global regular expression search and print), which has the same effect.
In computer science, an algorithm for matching wildcards (also known as globbing) is useful in comparing text strings that may contain wildcard syntax. [1] Common uses of these algorithms include command-line interfaces, e.g. the Bourne shell [2] or Microsoft Windows command-line [3] or text editor or file manager, as well as the interfaces for some search engines [4] and databases.

In the top figure the fraction 1/9000 in Excel is displayed. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. In the second line, the number one is added to the fraction, and again Excel displays only 15 figures.
A regex pattern matches a target string. The pattern is composed of a sequence of atoms. An atom is a single point within the regex pattern which it tries to match to the target string. The simplest atom is a literal, but grouping parts of the pattern to match an atom will require using ( ) as metacharacters.
If your search matches a page name exactly, search will navigate to the page directly instead of showing search results. To get search results instead, prepend the first word of the search string (i.e., the page name) with a tilde ("~"). (Or choose "Search for pages containing" from the suggestions that drop down as you type.)
Aston Villa (in 9 matches in 1981–82) and Milan (in 12 matches in 1993–94) hold the record for the fewest goals conceded by European Cup-winning team, conceding only two goals. In addition, Milan achieved the lowest-ever goals conceded-per-game ratio for Champions League-winning in the history of the competition (0.16).
If the set is tied at six games each, a tie-break is usually played to decide the set. A match is won when a player or a doubles team has won the majority of the prescribed number of sets. Matches employ either a best-of-three (first to two sets wins) or best-of-five (first to three sets wins) set format.
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.
