how about replacing dpkg -s lprng with grep -A1 '^Package: lpr$' /var/lib/dpkg/status and grep -e "^Status: install ok installed" with grep -q -e "^Status: install ok installed" (helps in suppressing unnecessary output) comparison times: dpkg -s lpr 5.71s user 0.37s system 35% cpu 17.182 total grep -A1 '^Package: lpr$' /var/lib/dpkg/status 0.00s user 0.04s system 155% cpu 0.026 total -john
