Rename file extension.
I have a list file that contains names of many files. I am reading one file name at a time using for loop
Then I like to create one more list file but with the file extension changed to "ctl".
Note: The file name can have any number of dots ".". But the extension after the last dot should be changed. And if there is no dot in file name it should append ".ctl"


Code:
for i in `cat listfile.txt`
do
    sed XXXX   >> New_listfile.txt
done



listfile contains data like this:

Code:
 abc.mnp.31235.txt
injo_kluo.miou.-mkop.pdf
12342_kjlu_3234.csv
integrate

I like the output in New_listfile like follows:
Code:
 
abc.mnp.31235.ctl
injo_kluo.miou.-mkop.ctl
12342_kjlu_3234.ctl
integrate.ctl

Help is really appreciated.
