Bash extended glob support

Bash extended glob support

In addition to the traditional globs (supported by all Bourne-family shells), Bash (and Korn Shell) offer extended globs, which have the expressive power of regular expressions. Korn shell enables this by default; in Bash, you can enable it using a command:

> shopt -s extglob

and disbale it using:

> shopt -u extglob

Example:

Suppose I want to list maven generated jars for all sub-projects from the root project folder but I want to exclude *javadoc.jar and *sources.jar files. This can be done as follows:

> ls -l */target/!(*javadoc|*sources).jar

Output:

root-project/sub-project-1/target/sub-project-1-<version>.jar
root-project/sub-project-1/target/sub-project-2-<version>.jar
root-project/sub-project-1/target/sub-project-3-<version>.jar
