Make changes en mass [done]

[Todd Snyder]

I am looking for a clever way to do the new serial number.  Date will do
the first bit no problem (date +%Y%m%d), but I'd love to find a clever
way to auto increment the last 2 digits unless it's a new day.  Then I
could use the same script every time.

/puts on thinking cap.

Good point.  

The serial number should be updated since the zone file is being
updated.  The sed command could be used to do that as well.

for zonefile in `ls *.com`
do sed -e s/604800/709600/ -e
s/200[0-9][0-1][0-9][0-9][0-9][0-9][0-9]/2009032401/ $zonefile
>${zonefile}.new
   mv $zonefile ${zonefile}.old
   mv ${zonefile}.new $zonefile
done

The above does the same expiration value replacement as earlier and also
changes the serial number to current day (2009032401 as of this
writing).   This substitution is based on the preferred serial number
syntax of:
CCYYMMDDsq where sq is a sequence number (01 being first).   It assumes
all the zone files have a current serial number using that in the
current decade (2000s) and no sequence number higher than 99.   The
pattern would have to be adjusted if those assumptions weren't valid.

To this point, nobody has updated the serial.
