Ruby Rename File
A File is an abstraction of any file object accessible by the program and is closely associated with class IO.
Renames the given file to the new name. Raises a SystemCallError if the file cannot be renamed.
Syntax
File.rename("afile.txt", "aewfwdf.txt") #=> 0
Code Example
File.rename(f, folder_path + "/" + filename.capitalize + File.extname(f))
File.rename("test.txt", "test1.txt")
Rename Files in Current Folder
folder_path = "." files = Dir.entries(folder_path).filter{ |dir| dir.include? "-1.svg" } p files files.each do |file| filename = File.basename(file, File.extname(file)) File.rename(file, filename.gsub("-1", "-active") + File.extname(file)) end
