How to implement dos batch replacement of current directory suffix name

This article mainly introduces how to achieve dos batch replacement of the current directory suffix, the article is very detailed, has a certain reference value, interested friends must read it!

Sometimes some suffix names do not meet the conditions, they need to be replaced in batches. If you replace them artificially, then if the quantity is small, then it would be silly to replace them one by one. Today, I looked up some batch replacement dos commands from the network, which are quite easy to use, so just paste the code here.

For example, sometimes the suffix name is jpeg, but some websites can only upload the suffix name of jpg for the sake of security, so you can use this to replace the tool in batch.

The code is as follows:

@ echo off

Set / p filename= Please enter the suffix name to replace:

Echo.

Set / p filename2= Please enter the suffix name after replacement:

Echo.

Setlocal ENABLEDELAYEDEXPANSION

For / f "tokens=*"% I in ('dir / b *.% filename%') do (

For / f "tokens=1 delims=."% j in ("% I") do ren "% I"% j.% filename 2"

)

Echo replaced successfully! Press any key to launch
