I'm writing a bash wrapper script that will pass arguments to the command. I need to find out the last argument if I call the wrapper as follows:

./wrapper -a -b --longarg=foo thisfilename.txt
./wrapper -a -b thisfilename.txt
./wrapper -a --next=true thisfilename.txt

Where,
=> $@ is all of them.
=> $0 is script name.
=> $1 is first arg.
