Code:

I get the following on a sample file with missing field:

Code:

Thu Aug 23 15:43:28 UTC 2018, hostname01, 232.02, 3, 0.00
Thu Aug 23 15:43:35 UTC 2018, hostname02, 231.09, 0.31
Thu Aug 23 15:43:37 UTC 2018, hostname03, 241.67, 4, 0.43

Thought the desired output (incorrectly done by the OP) would be:

Code:

Thu Aug 23 15:43:28 UTC 2018, hostname01, 232.02, 3, 0.00
Thu Aug 23 15:43:35 UTC 2018, hostname02, 231.09, , 0.31
Thu Aug 23 15:43:37 UTC 2018, hostname03, 241.67, 4, 0.43
