Thats right..
i have seen the thread in Tips and tutorials section by Perderabo..
he explains the way the Permission bit work...
But my clients reqirement is this way....
He wants users to execute the script but they should not be able to see the contents fo the script...
Its bascially a compilation script.
Every one is making a copy of it and manupilating its contents at there local level...and moving the generated load....
That is making problems as there are not using all the compiler options...
Is there no way that with out a read permission on a file we make the user to execute it for compiling the programs...???
