Full Discussion: Getting the file name passed to a shell script

The filename is never "passed into the script". By the time your script is running, all the redirection has already happened, it never gets told a thing about it. You're trying to go backwards from a file descriptor to a filename, difficult to impossible in a shell.

What's the filename needed for? Maybe there's another way to accomplish what you want without it.
