How to replace NewLine with comma using sed?
Hi ,

I have a huge file with following records and I want to replace the last comma with ',NULL'. I try using SED but could not create a correct script .

In my opinion I need a script which can convert ,/n with ,NULL/n



Code:
1,CHANGE_MEMBER,2010-12-28 00:05:00,2,CHANGE_MEMBER,2012-09-02 00:00:20,33,CHANGE_MEMBER,2010-12-28 00:02:10,4,CHANGE_MEMBER,2010-12-28 00:01:03,

Thanks in Advance
Ajay


Code:
 
$ cat test121
1,CHANGE_MEMBER,2010-12-28 00:05:00,
2,CHANGE_MEMBER,2012-09-02 00:00:20,3
3,CHANGE_MEMBER,2010-12-28 00:02:10,
4,CHANGE_MEMBER,2010-12-28 00:01:03,
 
 
$ awk '{sub(/, *$/,",NULL",$2)} {print$1 $2}' test121




Thanks,
R. Singh
