文件的当前名称:
Empty_test-one.txt , Empty_test-two.txt , Empty_test-three.txt
我只想重命名清空这个词。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文件并保留文件的第二部分(test-one,test-two,test-three)。
你能帮我吗?
答案 0 :(得分:2)
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新文件名,将old_name
更改为new_name
。
