Thanks Icd047, i partially achieved what i wanted to get here. Could you please explain a little bit about this awk command awk -F, -v OFS=, '{ if($1 ~ /^[ \t]*$/) $1 = old; else old = $1 } 1' Actually i am a novice to scripting and awk and if you could break this command and explain what it is doing, it would be really helpful for me in the future.

Also, is there a way to replace the datamash sum command with the general command where i can replace the sum operation with any other operation i want to perform? I have the requirement to perform various operations (like sum, average, calculate formulas) on the column values in each row in the CSV file which has multiple counter values in it. With the awk command you mentioned, i was able to repeat the date values in the empty columns which will really be useful to me.
