窗口文件批处理从空格重命名为下划线

Question

I'm trying to use a batch to rename a file from "aaa aaa.doc" to "aaa_aaa.doc"

I've written a script in the past to rename "aaa_aaa.doc" to "aaa aaa.doc"

@echo off
setlocal enabledelayedexpansion
for %%a in (*_*) do (
  set file=%%a
  ren "!file!" "!file:_= !"
)

How to modify from " " to "_" and ignore special symbol?

Answer 1

You've to reverse all steps and quote names with possible spaces.

@echo off
setlocal enabledelayedexpansion
for %%a in ("* *") do (
  set "file=%%a"
  ren "%%a" "!file: =_!"
)

Answer 2

ren "current_filename.ext" "new_filename.ext"
