Adding new column data in csv from UNIX
Hi I need to add new column data daily to existing csv file. Please assist

7/11 7/10 7/9 7/8
space 10 GB 20 GB

I was able to generate current day's data in csv but unable to add the previous 30 days data to the same csv

Please give us expected output. It is not obvious how 4 dates relates to the word space followed by 4 values or two two-word values:

1. 10
2. GB
3. 20 
4. GB

Is your csv space delimited, what is the field delimiter?
