A regular expression will do just fine.

entries.each do |entry|  
puts entry if entry =~ /^jpg\_image/  
end

Subject: simple get file by filename

Consider this:

I have a list of files that I get by calling:

Dir.entries(“/”)

I just want to search this list and match the file name that matches  
1\_1.\* ( i.e. the filename without the extension)

So, for example, If the pattern to match against the list was  
“jpg\_image.” it should return the filename “jpg\_image.jpg” (assuming  
the file exists).

What’s the most succinct way to do this in ruby?
