我需要根据用户的指示重命名多个文件的部分名称

I need to rename part of the name of multiple files, as per user's indication

当前文件名:

Empty_test-one.txt,Empty_test-two.txt,Empty_test-three.txt

我只想重命名 Empty 这个词。到目前为止我的代码:

puts "Indicate new name of files":
new_name = gets.chomp

# Look for the specific files
Dir.glob("*.txt").each do |renaming| 
  # Renaming of files starts, but not on every file
  File.rename(renaming, new_name + ".txt") 

我目前无法重命名每个单独的文件并保留文件的第二部分(测试一、测试二、测试三)。

你能帮帮我吗?

old_part = "Empty"

puts "Indicate new name of files":
new_name = gets.chomp

# Look for the specific files
Dir.glob("*#{old_part}*.txt").each do |renaming|
  full_new_name = renaming.sub(/\A(.*)#{old_part}(.*)\z/, "\1#{new_name}\2")
  File.rename(renaming, full_new_name) 
end

您缺少的是正确构建文件的新名称,将 old_name 更改为 new_name
