By default awk separates using space characters so it will handle to TABs as well as space. To make it e.g. use TABs only you can use:
Code:
awk -F "\t" 'NR==5{print $4}' infile

likewise for . or ,
Code:
awk -F. 'NR==5{print $4}' infile
awk -F, 'NR==5{print $4}' infile

To use any number of space characters only (and not TABs):
Code:
awk -F" *" NR==5{print $4}' infile
