Looking for a file somewhere in a directory recursively

[Ralph Shnelvar]

[Note: parts of this message were removed to make it a legal post.]

Assume I have a file pattern
temp*.bat

Assume I have a directory d:\XXX

and that I want to find all instances using Windows' file matching mechanisms rather than than Ruby regular expressions or the functionality of fnmatch.

In other words ... it _has_ to be the Windows file matching method exactly.


I see that FileUtils has a bunch of functionality but what I want is something like

X_FileUtils.dir("MyDir").pattern("*.bat") { |file| puts file }


Is there a gem "out there" to do what I want?

What about doing something like this:
result = %x[dir *.bat]

..and doing some basic parsing on the results?

What exactly do you mean by "Windows file matching method"? Windows
uses globbing very similar to most Unix shells. So as long as you
stick with using "*" and "?" you can just use Dir.glob or Dir.[].

=A0X_FileUtils.dir("MyDir").pattern("*.bat") { |file| puts file }

For the pattern above you only need

batches =3D Dir['MyDir/*.bat']

or if you want to get fancy:

batches =3D Dir[File.join('MyDir', '*.bat')]

For the fully recursive version you can do

batches =3D Dir['MyDir/**/*.bat']

and be done. No Gems required. You can even do

batches =3D Dir['MyDir/**/*.{bat,cmd}']

and really get all Windows batch files.

Kind regards

Is the stuff, above, some sort of 1.9 syntax? Do you really mean square brackets?

On 1.8 ... I cannot get anything you wrote, about, to work.

Different Rob(ert), but yes, there is a [] method defined on Dir

There's no reason to think that it wouldn't work on your Windows
system. Mine is a Mac, but the ruby code is the same:

irb> RUBY_VERSION
=> "1.8.6"
irb> Dir['*.rb']
=> ["listdiff.rb"]
irb> Dir['code/ruby/mailing_list/**/*.rb']
=> ["code/ruby/mailing_list/assoc.rb", "code/ruby/mailing_list/
merge_csv.rb", "code/ruby/mailing_list/sales_data_graph.rb", "code/
ruby/mailing_list/simulating_vehicles.rb", "code/ruby/mailing_list/
sorting_with_numbers.rb"]

Note that *I* have a code/ruby/mailing_list/ directory, but you'd have
to use directory names that exist on your system.

No. Yes.

Please show your IRB session / code and the errors you got.
