Add lines if they are missing from a data series
I have a data gathering device which records 5 attributes of data per second. The first column of the data is the time elapsed, in seconds, and is always sequential ie n+1. Data fields are comma delimited.
Randomly, the device doesn't record a sample and thus in the file there a skip of a second, and sometimes more. For example below sample number 167 is missing
166,1.09424,240,76,132
168,1.10088,215,76,132
169,1.10765,213,78,131
170,1.11458,198,79,131
and in this one, 284 and 295 are missing
292,2.04078,285,66,108
293,2.04673,302,64,108
296,2.06309,306,67,109
297,2.06859,370,66,109
The collected data will have an arbitrary number of lines/samples up to 1 million of more data points in a session. The number of dropped samples could be over 200, scattered randomly throughout.
I'm looking for a script or command that runs through the file and if a line is missing, will add a new line, and add the time stamp/sample number like this
166,1.09424,240,76,132
167
168,1.10088,215,76,132
169,1.10765,213,78,131
170,1.11458,198,79,131
or this
292,2.04078,285,66,108
293,2.04673,302,64,108
294
295
296,2.06309,306,67,109
297,2.06859,370,66,109
I found this answer which is a partial answer but gives lots of wrong new lines. I asked this question in a less precise form and got a better answer but it still didn't get me the solution.
Would prefer BASH script, using commands that run on OSX 10.14.2. Thanks in advance.
