# ouiparse.awk
# Author: Lawrence E. Rosenman <ler@lerctr.org>
# Original Date: 30 July 2000 (in this form).
# This AWK script takes the IEEE's oui.txt file and creates insert
# statements to populate a SQL table with the following attributes:
# create table oui (
# oui macaddr primary key,
# manufacturer text);
# the table name is set by setting the AWK variable TABLE
#
# we translate the character apostrophe (') to double apostrophe ('') inside
# the company name to avoid SQL errors.
#
BEGIN {
TABLE="macoui";
printf "DELETE FROM %s;",TABLE;
printf "BEGIN TRANSACTION;";
nrec=0;
}
END {
# if (nrec > 0)
printf "COMMIT TRANSACTION;";
}
# match ONLY lines that begin with 2 hex numbers, -, and another hex number
/^[0-9a-fA-F][0-9a-fA-F]-[0-9a-fA-F]/ {
# if (nrec >= 100) {
# printf "COMMIT TRANSACTION;";
# printf "BEGIN TRANSACTION;";
# nrec=0;
# } else {
# nrec++;
# }
# Get the OUI
OUI=$1;
# Skip the (hex) tag to get to Company Name
Company=$3;
# make the OUI look like a macaddr
gsub("-",":",OUI);
OUI=OUI ":00:00:00"
# Pick up the rest of the company name
for (i=4;i<=NF;i++)
Company=Company " " $i;
# Modify any apostrophes (') to avoid grief below.
gsub("'","''",Company);
# Print out for the SQL table insert
printf "INSERT INTO %s (addr, name) VALUES (trunc(macaddr \'%s\'),\'%s\');\n",
TABLE,OUI,Company;
