Clearing file contents
Hi,
Thanks for the reply...
But, as I mentioned earlier if the filesize is very large, say 500MB, then if I use the command ">filename", it will clear the file contents, but, when I do the "ls -l filename" it will will show the file size as 500MB itself, not as 0 bytes.
If the filesize is less, it will work without any problem.
It will be of great help, to get any other UNIX command which will clear the file contents.
Regards,
Raghu
