How long should replacing all white spaces with commas take in my 46MB text file using a simple text editor such as textmate on Mac?

Using sed
from Terminal this would take a few seconds:
sed -i "s/ /,/g" bigfile
(In my test, 565786 spaces in a 46 MB binary file were replaced in 2.1 seconds.)
Vim works too (:%s/ /,/g
) but was a little slower.
Edit: s/[[:space:]]/,/g
to include tabs (which, I assume, you meant by "whitespace")
What exactly are you asking? Have you tried it yourself? If yes, do you think it's taking too long? – Siim K – 2011-04-22T07:40:05.483
Should be near instantaneous, if not instant... – studiohack – 2011-04-22T07:40:12.077
This is 46MB... I dunno about textmate, but a lot of text editors choke on files that large, textmate may not be working 100% properly. – jcrawfordor – 2011-04-22T07:50:05.650
@nimble @studiohack It is actually running since 20 minutes. That's why I'm asking. I just need some quick tip how this is usually done. Maybe some other text editor? – aneuryzm – 2011-04-22T08:02:23.000
