Infrastructure Software

Hi all,
I have a sql procedure which formats some data and shows it using dbms_output.
I am calling this procedure in a shell script and redirecting the output in a file.
But somwhow,the files have tabs instead of spaces. The straneg thing is it does not replace all the spaces, but few of them.

The Unix team told me that I cannot use UTL_FILE to generate files.

I am not sure if this is a problem of dbms_output or of the shell script..??

This is urgent. Please help.

Thanks!
