Thanks for the reply but it's not quite what I need.

Code:
root@darkstar:~# ls /var/log/packages/glib2-2.18.1-i486-1gnome224jag 
/var/log/packages/glib2-2.18.1-i486-1gnome224jag
root@darkstar:~# installed=$(ls /var/log/packages/glib2-[[:digit:].]* | sed 's/\(-[^-]*-[0-9]\)\(.*\)/\1/g')
root@darkstar:~# echo $installed
/var/log/packages/glib2-2.18.1-i486-1   # installed != 1

root@darkstar:~# ls /var/log/packages/mozilla-firefox-3.0.2-native-1gnome224jag 
/var/log/packages/mozilla-firefox-3.0.2-native-1gnome224jag
root@darkstar:~# installed=$(ls /var/log/packages/mozilla-firefox-[[:digit:].]* | sed 's/\(-[^-]*-[0-9]\)\(.*\)/\1/g')
root@darkstar:~# echo $installed
/var/log/packages/mozilla-firefox-3  # installed != 1

As you can see (I forgot to mention), $NAME can also contain a hyphen sometimes so counting them out in the sed doesn't work half the time. $VERSION should always contain digits but may also contain letters. $ARCH could have either numbers and/or letters (native or i486). And $BUILD can also have both.

If I'm working with a package name like "xpaint-2.7.8.1-i486-2", then my old sed works fine.
Code:
root@darkstar:~# installed=$(ls /var/log/packages/xpaint-[[:digit:].]* | sed 's/^.*\(.\)$/\1/')
root@darkstar:~# echo $installed
2  # installed = 2

Thanks again. Much appreciated.

nwbpset

NWBPSET(1)							      nwbpset								NWBPSET(1)

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.
