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

Hi thanks for the reply,

But if it s ls -ltr > listed , the file will be created once, after which it throws a error if we run run the script next time. this script will be daily cron, so is there any other way to overwrite the file??

It should not throw an error. It should overwrite the file. If you have permissions to append, you have permissions to truncate.

What error does it throw?
