Replace content of txt

[batchrookie_99]

Hi everyone,

Just start learning batch command and can't figure out how to do this.

My question :
One folder has many .txt files and I want to replace their content.

001_Family.txt
002_Family.txt
003_Family.txt
...

The content likes below:
HelloWorld
HelloFriends
123456
...

I want to change "World" to "Family".
I knew how to read HelloFriend string and assign variable but don't know what to do next.

For %%A IN (*.*) Do Call :Check "%%A"
:Check
Set File=%~nx1
Set Change=%File:~4,6%
find "Hello%Change%" %File% > nul
???

Much appreciated

Do you just want to solve the task? Test this on copies of your files.

Code: Select all

@echo off
for %%a in (*.txt) do call jrepl "HelloWorld" "HelloFamily" /L /F "%%a" /O -

This uses a helper batch file called `Jrepl.bat` (by dbenham) - download from: https://www.dropbox.com/s/4otci4d4s8x5ni4/Jrepl.bat

Place `Jrepl.bat` in the same folder as the batch file or in a folder that is on the path.

Hi Foxidrive

Thanks for your help.
I downloaded the bat file and tried it.

It indeed changed the output result in command windows but I need the txt file content also be replaced.
Sorry for my unclear information.

For example,

The content of abc.txt
HelloWorld
HelloFriend

After executed XX.cmd

The content of abc.txt will be
HelloFamily
HelloFriend

Does this bat file has any function can do it? I barely understand these codes.

I just found I can use

for %%a in (*.txt) do call jrepl "HelloWorld" "HelloFamily" /L /F "%%a" /O > result.txt

I have no problem now,

You were clear, and my suggestion works fine here to change the files.

Make sure that the - character is at the end of the line.
