That is exactly what I said in my post before.

You have 2 options here:

1. Use ksh93 like elixir_sinari suggested
Code:
#!/bin/ksh93

2. Use sed like I suggested
Code:
startdate=$( echo $1 | sed 's/_/-/g' )

-d is not working in ksh.
Code:
enddate=`date -d "$enddate + $i day" "+%Y_%m_%d"`

If i remove -d from the above line igot the error called bad conversion

elixir_sinari already mentioned in his post that if you do not have GNU date then you will not be able to use -d option and perform date arithmetic.

I recommend you to take a look at this thread for alternatives.
