Thanks Joey. It worked great

Code:

sed 's/\(.\)dwh/\1\
dwh/g' inputFile

To avoid having 1st line as new line.

If the records are always by 8 columns. Here is a simple command.

Code:

xargs -n8 < infile

or by awk:

Code:

awk '{gsub(/dwh/,"\ndwh")}1' infile

Code:

 ruby -pne 'gsub(/dwh/,"\ndwh")' file
