Let's say I have a line with an undefined number of numbers in it, seperated by random text but surrounded by spaces. Something like this will do for an example:

/dev/hda5               303344     99042    188641  35% /

Basically, I want to take anything that matches this: m/ (\d+) /

...and do something to it (ie divide by 1024), then stick it back in where it was. It would be nice to be able to do this with perl -pe 'something', but I can't even figure out how to do it at all - how do I match once on a line, change something, then start matching again after the spot I changed on the same line?

For example, let's assume I wanted to take every big number i see in my input and turn it into that number divided by 1000. How do I do that?
