REGEX atomic groups `(?>)`
Explore the concept of REGEX atomic groups to control backtracking behavior in pattern matching. Understand how atomic groups differ from non-atomic groups by stopping backtracking after the first match, optimizing regex searches. This lesson helps you apply these principles in Bash shell scripting for more precise and efficient data processing.
We'll cover the following...
We'll cover the following...
By definition, a REGEX atomic group is a non-capturing group that exits the group and throws away all alternatives after the first match of the pattern inside the group, so backtracking is disallowed".
While a non-atomic group will allow backtracking, it will still find the first match, then if the matching ahead fails it ...
