wildcard

Let's get wild, stay active ✔️ A wildcard character is often used in searches and programming to represent one or more characters. The exact nature of how a wildcard character is used can vary depending on the context (such as SQL, shell scripting, or search engines).

Here’s an explanation of wildcard characters and their typical uses in various contexts:

SQL Queries:

% represents zero or more characters.
_ represents a single character.
Example: SELECT * FROM users WHERE name LIKE 'Jo%' would find any name that starts with "Jo".
Shell Scripting (Bash):

* matches any number of characters.
? matches a single character.

. matches any single character.
.* matches zero or more characters.

* or ? can often be used to represent unknown characters.

In general, wildcard characters are tools to simplify search patterns and data manipulation by allowing flexible matching criteria. If you have a specific context or example you need help with, please provide more details!
