Top Forums UNIX for Dummies Questions & Answers Trouble Assigning AWK variables Post 302577714 by agama on Tuesday 29th of November 2011 06:22:36 PM

If you are using a modern awk (nawk on a sun) then this will work:

Code:
read ratio
awk -v ratio=$ratio '{if($1 == "variableStep") {print $0} else {$2*=ratio;{print $0}}}' ${NAME}.wig > ${NAME}normalized.wig

And a suggestion to make it a bit easier to read:
Code:
awk -v ratio=$ratio '
{
  if( $1 != "variableStep") 
     $2 *= ratio;
  print;
}' ${NAME}.wig > ${NAME}normalized.wig
