Shell script to overwrite a file

Hi Guys,

My requirement as follows,

i want to write a shell script to display the files of a folder, i export it to a file to mail the file. The problem is the exported file is getting appended every time I run the script. I just want the file to be over written. can anyone suggest??
Code:
#./bin/bash
ls -ltr >> listed
ls -ltr | wc -l >> listed
mail -s "listed" abc@yahoo.co.in < listed

Regards
Karthick
