Randomly replacement in textfile via batch

I have a textfile (.txt), that is built like this:

;ARPE for Ariminum
event   plague  ARPE_RIDaba
date    RND summer
position    96, 81

;ARPE for Tara
event   plague  ARPE_RIDbbg
date    RND summer
position    34, 143

Now I need a batch script, which will replace all the "RND" in my file with a random number between 1 and 250 (no comma, only whole numbers). But I do not want every RND to become the same. I want each RND to be assigned random and independent from the others. Also, the text file is coded in UTF-8 without BOM and it must stay like this.

Is there any solution for that?

You could use my JREPL.BAT regular expression text processing utility - pure script (hybrid JScript/batch) that runs natively on any Windows machine from XP onward.

call jrepl "\bRND\b" "Math.round(Math.random()*250)+1" /j /f test.txt /o -

The above will write all lines with \r\n line terminators, regardless what form the original had. If you want to preserve the original line terminators, then you can add the /M multi-line option:

call jrepl "\bRND\b" "Math.round(Math.random()*250)+1" /m /j /f test.txt /o -
