JavaFind

This is a 100% Java implementation of the familiar Unix find utility. Being a Java library, it's very easy to integrate into any Java application. It provides flexible cross-platform file searching.

Features

Automatically detects and delegates work to GNU find & perl when it will save time. This can be controlled via the system property:

-Djavafind.allowoptimize=[on|off|regex]

on = Always delegate to GNU tools if it can.
off = Never use GNU tools - always use 100% Java.
regex = (default) Use GNU tools only when a regex has been
specified.

Set the following property to see at runtime what the optimization status is:

-Djavafind.debug=true

Allows matching filesnames based on Perl 5 style regular expressions.

The library can be used from other Java classes, or from the command line.

Supports some useful GNU find-like functions:

mindepth - Specify a minimum depth to begin finding files at
maxdepth - Specify a maximum depth to search
follow - Can be set to follow or not follow symbolic links on unix computers. This needs more testing on Windows.
file types - "Directory" and/or "Plain file" can be specified

Supports some extra options from other GNU tools:

negated - Specify if files NOT matching the regex should be returned. (The idea for this was taken from egrep's handy -v option.)
exclude dirs - Specify a set of directories to exclude from the search. (The idea for this was taken from tar.)

Has a useful public method, "isSymLink()".

Requirements

This package requires Jakarta ORO for regex matching.
