Too simple to search for

Hey. I'm just getting started with scripting and although i will admit i haven't searched the forum yet, i think it would be a waste of time. It really will be very simple.

I want to enter a list of arguments after my script with the last being the filename. (not the first, as this is part of the requirements)

I so far have

Code:

var=$#
filename=$var
echo "last argument is $filename"

Now i have put every variation i can think of around the second lines var in order the change the value of filename to be from the location in the list of arguments to the argument itself, ie if i put

sh script hi there smelly

smelly is the last argument.

i want the filename to take on the value of the file smelly, not the value 3 (3rd argument)

if i put sh script hi there scriptfile1
where scriptfile1 exists and is the file i want to to point to, it still has argument 3. Whilst I would rather have it point to a file that already exists, i don't mind if it creates a new tempfile, (and will do checks on if files exist once i can get this sorted) i would just like to know how i can have it point to a filename rather than the argument number.

I'm sure i've made that a lot more difficult that it is, but any advice would be appreciated.

Regards, and thanks for your time!

Mitch.

vamp-simple-host

VAMP-SIMPLE-HOST(1)					      General Commands Manual					       VAMP-SIMPLE-HOST(1)

NAME

       vamp-simple-host -- a simple Vamp plugin host

SYNOPSIS

       vamp-simple-host [-s]  [pluginlibrary[.so]:plugin[:output]]  [file]  [-o outfile]

       vamp-simple-host [-s]  [pluginlibrary[.so]:plugin]  [file]  [[outputno]]  [-o outfile]

DESCRIPTION

       This manual page documents briefly the vamp-simple-host command.

       vamp-simple-host  allows processing of a libsndfile-readable audio file using Vamp plugins, listing available plugins and the plugin search
       path.

       By default, vamp-simple-host loads plugin id plugin from pluginlibrary and runs it on the audio data in file, retrieving the named  output,
       or output number outputno (the first output by default) and dumping it to standard output, or to outfile if the -o option is given.

       pluginlibrary  should  be a library name, not a file path; the standard Vamp library search path will be used to locate it.  If a file path
       is supplied, the directory part(s) will be ignored.

       If the -s option is given, results will be labelled with the audio sample frame at which they occur. Otherwise, they will be labelled  with
       time in seconds.

OPTIONS

       -l, --list
		 List the plugin libraries and Vamp plugins in the library search path in a verbose human-readable format.

       --list-full
		 List all data reported by all the Vamp plugins in the library search path in a very verbose human-readable format.

       --list-ids
		 List the plugins in the search path in a terse machine-readable format, in the form vamp:soname:identifier.

       --list-outputs
		 List the outputs for plugins in the search path in a machine-readable format, in the form vamp:soname:identifier:output.

       --list-by-category
		 List the plugins as a plugin index by category, in a machine-readable format. The format may change in future releases.

       -p	 Print out the Vamp library search path.

       -s	 Label results with the audio sample frame at which they occur. Otherwise, they will be labelled with time in seconds.

       -o file	 Dump plugin output into file.

       -v	 Display version information only.

ENVIRONMENT

       VAMP_PATH A colon-separated list of directories to look for plugins.
