Questions tagged [wildcard]

A wildcard character is a specially defined character allowing for substitution of any other character, including a pattern or sequence of characters. Use this tag for questions on how to use wildcards for regular expressions, shell scripting, string manipulation and database control, but not for use in terminal commands as that is off-topic.

A wildcard character is a special character defined by many different systems/programming languages with each their own specific implementations. They may allow for accessing single characters, sets of characters or all characters matching a certain regex pattern.

Examples include :

* - Any sequence of characters. (DOS/Unix)
? - Any single character. (DOS/Unix)
% - Zero or more characters. (SQL)
# - Matches a single numeral. (SQL)
. - Matches a single character. (Regular Expressions)
