I was wondering if someone could help me write a batch file to find and replace text in a text file. I have web urls on a website and need to replace 5 specific html codes with the real characters. The 5 things I need to change throughout the text file are as follows

Find Replace
---- -------
%26 = &
%2F = /
%3A = :
%3D = =
%3F = ?

I will keep adding new urls to a text file; say named a.txt or something and I want the batch to parse the text file and replace the characters... I learn better by using examples and experimenting with them so could someone please write this file for me and I can see how it works. I am fairly familiar with cmd and batch etc..., I've just never needed to do this before. I would appreciate any help.

It works as expected:

HI, thanks for the reply, but I am not sure how this is supposed to work. I tried just running this, then I tried placing this in the same folder as the text and running, then I tried using cmd to run this batch a.bat a.txt and it didn't work. Changed nothing in the text file. Is the ) missing at the end of your script? I tried with and and without it and it still did nothing.

This was an example. It works also on text files:


Edit: delims added.

Awesome!! Worked perfectly! Now I'll create adifferent version based on this to better suit my needs, much appreciated.
