Hi,

I have a script output file that looks like
device date size free
- -- -------------- ----- ----- -----
RAW01 Nov122005 120g 102g
RAW02 NOV122005 120g 102g

I would like to just filter out the 3rd column(size) and then add the
values (or it can be more as well). So it should be
120 + 120 = 240. Based on how this value is divisible by 5, I want to
write more case statements.

Could you me how to just strip the 3rd column and add the values
in a Korn shell script.

shell is an environment you use to call tools, it's rarely the best
choice for writing text processing scripts. In this case, it's trivial
in awk:

awk '{tot += $3}END{print (tot%5 ? "not " : "") "divisible by 5"}' file
