Top Forums UNIX for Dummies Questions & Answers How to log transform a text file? Post 302564783 by Corona688 on Friday 14th of October 2011 03:17:05 PM

I'll take a wild guess and say log. But that's likely to be log e, not log 2. Easy conversion though, just divide by log e(n) to get log n.
Code:
awk '{ $1=log($1)/log(2) } 1' < infile > outfile
