Several methods accept a file pattern to selectively normalize files. Patterns may include:

• '*' to match any number of characters
• '?' to match any single character
• '**' to match any number of directories or files

Either '/' or '\' may be used in a pattern to separate directories. Patterns ending with '/' or '\' will have '**' automatically appended.

Examples:

 all files ending with '.json' (including files in subdirectories)
    **/*.json
 

 all files beginning with 'build-' in the level1/level2 directory
    level1/level2/build-*
 

 all files (including subdirectories) beneath config/build-data
   config/build-data/
 

 all properties files in a build directory beneath com/acme (including subdirectories)
   com/acme/**/build/*.properties
