Re: One-liner (or few-liner) for massaging regexps?

use df -m to get megabytes? :)

Oh, you mean in perl...

perl -pe's{(\d+)}{($1>1024)?(int($1/1024)):$1}eg;'

The only problem with this is that what you replace isn't going to be the same width as what you removed, which could mess up columns.

perl -pe's{(\d+)}{($1>1024)?(sprintf("%".length($1)."d",$1/1024)):$1}e
+g;'

That variable sprintf can be easier written as `perl -pe's{\b(\d+)\b}{ sprintf "%d", length $1, $1/1024 }ge'` Update:* added `\b`s - thanks to sauoq. Makeshifts last the longest.	[reply] [d/l]
