a quick SED question

I have a line

Code:
EXTDIR=`echo $i | sed 's/\-tar.gz//'`

which looks for files ending in -tar.gz, i would like to increase the functionality so that it looks for .tar.gz files as well as -tar.gz. Do i put the - in square brackets with a dot ? like this

Code:
EXTDIR=`echo $i | sed 's/\[-.]tar.gz//'`

unfortunately i dont have my box at hand to test this but i would love to know so i can be prepared

any help on this would be greatly appreciated
Gary

virt-tar-out(1) 					      Virtualization Support						   virt-tar-out(1)

NAME
virt-tar-out - Pack a virtual machine disk image directory into a tarball. SYNOPSIS
virt-tar-out -a disk.img /dir files.tar virt-tar-out -d domain /dir files.tar virt-tar-out -d domain /dir - | gzip --best > files.tar.gz DESCRIPTION
"virt-tar-out" packs a virtual machine disk image directory into a tarball. The first parameter is the absolute path of the virtual machine directory. The second parameter is the tar file to write. Use "-" to write to standard output. EXAMPLES
Download the home directories from a guest: virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command. For anything more complex than a trivial copy, you are probably better off using guestfish directly. OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options. SEE ALSO
guestfish(1), virt-cat(1), virt-copy-in(1), virt-copy-out(1), virt-edit(1), virt-tar-in(1), <http://libguestfs.org/>. AUTHORS
