Searching comma's

I have a delimited file. Each line consists of 5 fields separated by commas.so each line should consists of 4 commas. But due to some quality issue few lines consists of extra comma. need to print those odd lines.
need an unix command to find out those lines

Code:
100, Peter,12, 24 cromwell street, Mgr
101, Tom,12, 24 cardington square, Supervisor
103, Bob,12, 23 Beaver,cres, Steward

Hi, try:
Code:
awk -F, 'NF>5' file

It prints lines where the number of fields (NF) is more than 5, using a comma as a field separator (-F,)

Hello pranabpal,

It would have been better to show what you had tried so we can see your preferred style/tools etc. That way we would find a solution that you could understand better when you come back to the code in a few years time for any reason.

Do you have a plan for how you would achieve this with processes you already know? We could help adapt them.


In any case, another option (and there will be plenty more:-
Code:
egrep "(.*,){5}" file

This will find any rows with 5 commas, however rows with more commas are also collected because the search for 5 is contained within them.
If you want to find rows with fewer that 4 delimiters, try this variation:-
Code:
egrep -v "(.*,){4}" file

This will find any rows with four commas and then the -v flag will exclude them, so you get anything less than four reported.




I hope that these help,
Robin
