"File name too long" error?

[bczhc]

I use this Ruby script to create a very large amount of recursive files and directories.

#!/bin/env ruby

require 'fileutils'

while true do
  name = (0...255).map { ('a'..'z').to_a[rand(26)] }.join
  puts name
  Dir.mkdir name
  Dir.chdir name
  File.open(name.reverse, 'w') { |x| x.write "hello" }
end

After running it a short while (~ 1s), I use fd to list them and get the total file count. But the result of fd differs from find.

/mnt/hdd/depth ❯ find . | wc -l
1695
/mnt/hdd/depth ❯ fd | wc -l
31

When I use fd --show-errors, it shows that a File name too long error is encountered:

/mnt/hdd/depth ❯ fd --show-errors | wc -l

How can I get rid of this? Looks like when I attempt to open a file with long path name, it has "File name too long" error; but I just want to simply list them.

Thank you for reporting this. I opened a bug ticket instead, which seems more appropriate: #1322
