Rename multiple files

Ruby

Hi,

Could anyone help me in writing a code which could replace file names
letters to lowercase and spaces to dashes? For example:

Ruby Forum to ruby-forum

Thanks.

hi Jonas Jonaitis

Assume Filename is Ruby Forum

File.rename(Filename, Filename.downcase!.gsub!(32.chr,’-’))

This would work.

path = “D:\Images”
Dir.open(path).each do
File.rename(Filename, Filename.downcase!.gsub!(32.chr,’-’))
end

What I would also really want is to set a path to a folder with multiple
files and enter a code, so it would make the changes to all file names.

My code is missing something.

i don’t understand exactly what are you asking here,

Do you want to change the name of all the files(downcase and - included)
under a particular folder?

It’s sorted now, thanks.

path = “D:\Images”
Dir.open(path).each do |p|
next if p.match(/^./)
old = path + “\” + p
new = path + “\” + p.downcase.gsub(’ ', ‘-’)
File.rename(old, new)
puts old + " => " + new
end

You might find it more efficient to check that the file actually needs
renaming as well. With your current system you’re carrying on
regardless.

Filename=‘Ruby Forum’

This would work.

This might not work because the bang versions return nil if no change
was made.
