Hi folks,

Which built-in method is used to search a file in a directory and all
its children directory?

Thanks,

Li

As always, there are more ways, depending on what you want to do. For
simple searching of a file by name Dir is easiest. Find is more
appropriate for tasks that have to deal with every file etc.

http://ruby-doc.org/stdlib/libdoc/find/rdoc/...

Yup, I was looking for something similar, a simple way
to get the functionality of the unix "find" command.

I was motivated by the slow search facility under XP. Not
sure if ruby might be faster, but it made me curious how
I would specify a file to be found in a directory tree.

As a newbie I am still not quite familiar with all of the
facilities or libraries, maybe it's obvious :-)

Me, too. I need to spend some time to read the documentation and figure
out how to write the script.

Didn't you see my last reply? Do we have a gateway problem again?

Yes if you mean the information on the previous post:
....
http://ruby-doc.org/core/classe...
http://ruby-doc.org/stdlib/libdoc/find/rdoc/...

As I reply to EB I need time to read the doc and write the script by
myself.

No, there was another posting. I realize it is in another thread:

Hi EB,

I think Robert kindly provies a pretty neat script which is what I want.
I am not sure if you also need a similar one like this, which searches a
directory and all children directory for the file specified.

Li

###
require 'find'

path='I:/Common/xxx/Notebooks/Flow/OT1/OTI-4'

file_number = 0

Find.find(path) do |f|

puts f if File.file?(f) && f=~/\.\d+$/
# print out the file with format xxx.001 xxx.002...
file__number+=1

end

puts file_number

We took some pretty drastic measures when we addressed the last
Gateway issue and haven't seen a thing since. I think we have it
pretty locked down now.
