Replacing strings in MSDOS

[krivokapa]

Hi,

I'm having difficulty to replace strings in a twxt file, so I was wondering if anyone could help.

In file text.txt I need to replace string that starts with "myString……..." with string "yourStringABC". So the example of text.txt is:

Text.txt
---------------------

My name is Diana
My age is 19
My occupation is student
I have myStringxxxxxxxx
Please help to replace this string

----------------------------

After replacement the file should look like:

Text.txt
---------------------

My name is Diana
My age is 19
My occupation is student
I have yourStringABC
Please help to replace this string

----------------------------
In this original file xxxxxxx can be anything but I know that it does not contain any spaces.

Anyone done this before?
Thanks,

The best way to deal with is to look for some ready to use batch file. This files are already made to play with dos string manipulation. I have a solution for the same. For the replacement of the substring with an different string you will need to use the feature of string substitution. The script for the same will be somewhat like this :

1. set str=xxxxx cat in teh hat
2. echo.%str%
3. set str=%str:xxxxxx=yyyyyy%
4. echo.%str%

Follow the above procedure for your support.
