replace multiple patterns in a string/filename

This should be somewhat simple, but I need some help with this one.

I have a bunch of files with tags on the end like so...

Filename {tag1}.ext
Filename2 {tag1} {tag2}.ext

I want to hold in a variable just the filename with all the " {tag}" removed. The tag can be anything so I'm looking to replace " {*}" with "". Note the space before the {. I also do not need the extension. The purpose of this is to create a directory with the same name as the file without tags (and extension).

I just need help replacing the " {*}" patterns in the file name.

This somewhat works, but only does one tag and " {new version}" is the exact string replaced.

Code:
i="Filename {download}.ext"
NOTAG=`echo $(basename "$i") |awk '{sub(" {new version}","")}1'`

mkdir -v /path/$NOTAG

Much Thanks

Try this instead:

Code:
NOTAG=`echo ${i} | cut -d' ' -f1`

port2,

That code only returns the string up until the first space.

FilenameABC With Spaces {tag} (tag}.ext -> FilenameABC

I'm trying to get "FilenameABC With Spaces". Just replacing "<space>{<any text>}" with "". Maybe regex is needed (which I was never good at)?

Try this:
Code:
var="FilenameABC With Spaces {tag} (tag}.ext"
NOTAG=${var%{*}

Franklin, that worked. I knew it wasn't too complex. Strange that you don't need a $ in front of var. But I'm still learning.

Thanks a bunch!
