Question

How can I change about ~40000 values, using regex(?) higher than 200000?

Fe. Search for value > 200000, replace for: 200000 – 123456.

I have no idea, if it’s possible in the Notepad++, or I have to use some other methods like PHP?

Answer 1

There are many tools to do that, one of them is perl:

perl -pi -e 's,(\d+), ($1 < 200000) ? $1 : ($1 - 123456) ,ge' yourfile

Sample:

fge@erwin ~ $ perl -pe 's,(\d+), ($1 < 200000) ? $1 : ($1 - 123456) ,ge'
I have 3 apples and 290000 oranges   # input                                                                          
I have 3 apples and 166544 oranges   # output                                                                          

If you have cygwin installed and perl, you are set.
