So, I wrote a little nawk script that will take a
new /etc/aggregation.conf, and add the "/0" port numbers to the
component link names of aggregations. It doesn't touch comment lines
and blank lines:
BEGIN {
space = "[ \t]";
blanks = space "*";
blankline = "^" blanks "$";
comment = "^" blanks "#";
}
$0 ~ comment {
print;
next;
}
$0 ~ blankline {
print;
next;
}
{
numlinks = split($4, links, ",");
newlinks = links[1] "/0";
for (i = 2; i <= numlinks; i++) {
newlinks = newlinks "," links[i] "/0";
}
print $1 "\t" $2 "\t" $3 "\t" newlinks "\t" $5 "\t" $6 "\t" $7
}
Since I'm no awk/nawk expert, I'm sure the above script could be made
more compact or cleaner. So, awk experts, what say you?
Thanks,
