how can we remove the text before the line that start's with second comma(line 5 in the example),how can i do that using regex? example :
,
abc,xyz,ggg,nrmr
cde,jjj,kkkk,iiii,tem,posting
234,mm/dd/yy
,
454654,output2,sample
45646,output1,non-sample
16546,225.02
ABC,2.98
expected :
454654,output2,sample
45646,output1,non-sample
16546,225.02
ABC,2.98
