Uninstalling Blastwave (or any other package group) with a bit of Shell Scripting on Solaris.

Let's say we've installed a bunch of Solaris packages from Blastwave or another source and want to remove them all without going through the boring process of answering all those questions:

$ pkginfo | grep CSW
system CSWcommon common - common files and dirs for CSW packages
application CSWexpat expat - XML Parser Toolkit
system CSWggettext ggettext - GNU gettext
application CSWglib2 glib2 - the low-level core library for GTK+ and GNOME
system CSWiconv libiconv - GNU iconv library
application CSWmc mc - GNU Midnight Commander
system CSWpkgget pkg_get - CSW version of automated package download tool
system CSWslang slang - library primarily to provide an alternative to libcurses
system CSWsunmath libsunmath - Sun maths library

Well, nothing simpler:

# yes | pkgrm $(pkginfo | grep CSW | awk '{ print $2 }' | xargs)

The following package is currently installed:
CSWcommon common - common files and dirs for CSW packages
(i386) 1.4.5

Do you want to remove this package? [y,n,?,q]
## Removing installed package instance
## Verifying package dependencies in global zone

Removal of was successful.
# pkginfo | grep CSW
#

Since Blastwave installs by default in /opt/csw, you can probably remove that too if you don't have settings you plan on keeping:

# rm -rf /opt/csw

Enjoy :-).
