awk help

HI,

I have a .csv file , I am trying to remove the first column and load the remaining columns.

MY code.

Code:
awk 'BEGIN { FS=","; OFS="," } {$1="" , $0)}1'  source.csv > target.csv

I am getting the output but there is one additional "," of the first column which I am not able to remove, how can I remove this.

sample output from the above code
Code:
 ,2,3,4,5
 ,3,4,5,6,
 ,3,4,5,6

--Mora

Maybe use cut instead?
Code:
cut -d, -f2- source.csv > target.csv

Code:
| sed -n 's/,//p'
