Parse an RPM name into its components - fast

parse_rpm() { RPM=$1;B=${RPM##*/};B=${B%.rpm};A=${B##*.};B=${B%.*};R=${B##*-};B=${B%-*};V=${B##*-};B=${B%-*};N=$B;echo "$N $V $R $A"; }
parse_rpm xorg-x11-fonts-ISO8859-1-75dpi-7.1-2.1.el5.noarch.rpm xorg-x11-fonts-ISO8859-1-75dpi 7.1 2.1.el5 noarch It's a little tricky because RPM names can contain '-' and the name, version and release number can contain '.' This is one or two orders of magnitude faster than using rpm itself: rpm -qp --queryformat '%{N} %{V} %{R} %{ARCH}\n' $RPM
