Please use Code tags!

There should be space not 'test, it should be ' test

Just redirect like this
Code:
inputfile > outputfile

Code:
' test > test_outputfile

Thanks a lot. It works perfectly. But now my data is screwing me....

My data has the below patters....

Mon DD YYYY
Mon DD YYYY
Mon D YYYY
Mon D YYYY

So I am not able to predict the pattern. some of my patterns are Mon DD YYYY and not getting converted. Not sure why....
