Finding files in a directory and regexp

ruby-talk
1

Hello,

I am doing something like this:

  Find.find("/Users/alamb/_Current-Work/fiches") do |path|
    if(path =~ /100_/)
    ...

In order to get all the files of the directory which have "100_" in the name.

Two questions:

1) Is there a way to use the find method to directly achieve this?
2) I tried a Regexp with /^100_/ to say "files starting with '100_' " but it doensn't seem to work.

Any idea?

Thanks

I don't usually use Find... Dir is fairly powerful.

   Dir["100*"] # all 100-type files in current dir
   Dir["**/100*"] # all in this tree (correct syntax??)

One could use Rio (rio.rubyforge.org)

This would find the files which start with '100_'

rio("/Users/alamb/_Current-Work/fiches").files(/^100_/) do |path|
  ...
end

To include files in subdirectories that start with '100_' use:

rio("/Users/alamb/_Current-Work/fiches").all.files(/^100_/) do |path|
  ...
end
