Fedora :: How To Keep Script From Over Writing Enviornmtent Variables

#! /bin/bash
#SCRIPT FOR DISPLAYING INODE, FILE PERMISSIONS ETC OF COMMAND ARGUMENTS
for data in $@
do

[code]....

The sript above is executed:-

./script file1 file2 file3 file4 file 5...

The error is that instead of showing the inode etc, of the ALL FILES IN COMMAND LINE ARGUMENTS, THE SET COMMAND OF LINUX OVER WRITES THE $@, so only "ls -l' of 1st commadn argument(file1) is displayed. The script should display it for every file in linux directory.
