ReDirect Problem
when I want to redirect output of a program to a file, why does the file appear as an executable after the data has been written to it? Here is the line that opens the file
open(filename,O_WRONLY|O_CREAT|O_TRUNC,S_IRWXU); Thanks!

S_IRWXU means "read, write, execute -- user" and should generate a file mode of 0700.
Read-only for owner is S_IRUSR and write-only is S_IWUSR. You might get the "read & write, but not execute" with (S_IRUSR | S_IWUSR). Otherwise, you might want to set your umask to mask out the execute (umask == 0111). Or call chmod() to turn executable off.
