And then..the script:
BEGIN {
# set the variables for the address change
# * * * * * * * * * * * * * * * * * * * * * * * *
# Make sure you leave the $ at the end of the oldip address
# to take care of the situation where the last octet is less thatn
# three digits in decimal
Not necessary.
# * * * * * * * * * * * * * * * * * ** * * * * *
# oldip="192.168.0.13$" changed to below
oldip="192.168.0.13"
newip="192.168.0.123"
}
{
# increment the serial number which should be the line directly below
# the SOA line
if ($0 ~ /SOA/) {
print;
getline;
ser_no = $(1);
restofline = substr( $0, index( $0, /;/ ) + 1); # get rest of line
print "\t\t\t\t" ++ser_no restofline;
}
else {
if ( $0 ~ oldip))
gsub(oldip,newip);
print
}
}
