How to do a "sed -" like operation on Windows?

Question

I have a large 55 GB file in which there is a sentence on every line. I want to check if there are any lines that have a dot "." at the end, and then if there is, I want to insert a space before the dot in that line.

Ex: I like that car. Replace with: I like that car .

A space before the trailing dot on every line if there is a dot.

I don't have any cygwin or unix and I use a windows OS. Is there a sed like common that I can do on this 55GB! file?

I tried GetGNUWin32 but I am unable to determine the actual command there.

Answer 1

Install Perl. Strawberry Perl is probably the best distribution for Windows. http://strawberryperl.com/

To do what you're talking about in Perl, it would be this:

perl -p -i -e's/\.$/ ./' filename

Answer 2

You can install Cygwin and use sed from there. And here I found Sed for Windows

Edit:
Very Good Answers to your Question: Is there any sed like utility for cmd.exe

_{(I always prefix stackoverfloew when I search on google. Same I did for you on google: sed on window stackoverflow, but that is different matter)}
