Description
This is a drop-in replacement for the find module currently in the standard
library. It is modeled on a typical 'find' command found on most Unix systems.
Installation
gem install file-find
Synopsis
require 'file/find'
rule = File::Find.new(
:pattern => "*.rb",
:follow => false,
:path => ['/usr/local/lib', '/opt/local/lib']
)
rule.find{ |f|
puts f
}
Rationale
The current find module in the standard library is inadequate. It is, quite
frankly, not much more than a plain Dir.glob call. This library provides an
interface based on options typically available on your command line 'find'
command, thus allowing you much greater control over how you find your files.
Options
* atime
* ctime
* follow
* ftype
* inum
* group (name or id)
* maxdepth
* mindepth
* mount
* mtime
* name (or 'pattern')
* path
* perm
* prune
* size
* user (name or id)
In addition to the above options, FileTest methods such as 'readable?' and
'writable?' may be used as keys, with true or false for their values.
See the RDoc documentation for more details about these options.

Options I won’t support
Generally speaking, anything that would require mucking around with C code
or is just too difficult to implement in a cross platform manner will not be
supported. These include the following options:
* acl/xattr - Way too difficult to implement in a cross platform manner, and
a rarely used option in practice.
* cpio/ncpio - I will not shell out to this or any other 3rd party
application.
* ls/print - Use Ruby's builtin printing methods to print as you see fit.
* ok - This is not interactive software.
Known Issues
The mindepth and maxdepth options do not work for more than 1 path.
The :perm option is limited to 0644 and 0444 on MS Windows.
The :user, :group, and :inum options require the win32-file gem to work
properly on MS Windows. However, it is not officially a dependency.
There are 3 test failures with JRuby, all related to the 'perm' option. I
have not been able to reduce them to a simple test case and discern the
exact cause of the failures, though I suspect a bug in the JRuby
implementation of File.chmod.
Bugs
None that I'm aware of beyond the ones mentioned in the Known Issues. Please
