possible sed usage

Sorry about the title. I'm assuming I want sed anyway...

Here's the deal:

I have hundreds of files in a folder and they all are named with the same format.

$NAME-$VERSION-$ARCH-$BUILD

This is Slackwares' /var/log/packages directory BTW...

$BUILD is what I'm focusing on. It could be just "1" or it could be "1foo" or it could be "1foo357" or "1foo357bar"

I'm trying to isolate just the "1" regardless of what comes after it. I came to the conclusion that just identifying the last hyphen and then grabbing the very next number would be the easiest way.

This is what worked great until I started adding custom build tags like foo and foo357:

Code:
installed=$(ls /var/log/packages/$NAME-[[:digit:].]* | sed 's/^.*\(.\)$/\1/')

so if $build = 1foo357bar, then the above gives me "r"... The number I want will ALWAYS be after the last hyphen. There is a small chance that the number could reach double digits but it would be rare.

Any ideas? Thanks much for your help. I'm really stumped for some reason.

NAME
nwbpset - Create a bindery property or set its value SYNOPSIS
nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] DESCRIPTION
nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with As another example, look at the following command line: nwbpvalues -t 1 -o supervisor -p user_defaults -c | sed '2s/.*/ME/'| sed '3s/.*/LOGIN_CONTROL/'| nwbpset With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object 'me'. nwbpvalues -t 1 -o me -p login_control -c | sed '9s/.*/ff/'| nwbpset This command disables the user object me. Feel free to contribute other examples! nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons. OPTIONS
-h -h is used to print out a short help text. -S server server is the name of the server you want to use. -U user user is the user name to use for login. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset prompts for a password. -n -n should be given if no password is required for the login. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. AUTHORS
