Need Help with making a bash script

I have two problems.


1. I'm making a script to add IP's to my blacklist...

I need to add three , the word 'REJECT' and a #DDMMYYYY that it's
being done to a text file that has the IP's in it... ie this is the
original list;

80.25.148.216
80.43.197.197

needs to end up like this...

80.25.148.216 REJECT #28052004
80.43.197.197 REJECT #28052004



2. The second is a little bit more complicated.

My server is having trouble deleting virus emails, I want to help it
along with a little cron job that will clear out virus emails every 10
minutes or so. I get the list of infected emails from the maillog but in
the maillog only the email ID is displayed. In the actual queue there
are two files per 1 email ID.

ie... this is what the log spits out as emails that are infected that I
want to delete...

foo1
foo2
foo3

but in the queue there are two files per email, a qffoo and a dffoo so
in the queue the previous emails would actually be...

dffoo1
qffoo1
dffoo2
qffoo2
dffoo3
qffoo3

So, is it possible to run rm with a wildcard to compensate for the df qf
letters and still feed it the list of email ID's which make up the last
part of the df qf files?


don't have a clue where to start, thanks

I just happen to have almost exactly such a script running here. The
relevant part is this one here, modified to your needs. It requires that
you set SOURCEFILE to whatever file you use. Same for DESTFILE. I didn't
put any secure checks for either source or dest in there, just FYI.

rm $DESTFILE
cat $SOURCEFILE | while read TCPREMOTEIP
do
echo "$TCPREMOTEIPREJECT #`date +%Y%m%d`" >> $DESTFILE
done

The same thing can probably also be done faster with sed.

Yes, simply run it with wildcards like this: rm ??foo1

Hope this helps

ip.bsh expects a file with ip addresses named ip.in in the same directory.
It will produce ip.out. Don't cut-n-paste the script as you'll probably
lose the tabs (they've been entered with + in vi, in case you
wondered).

email.bsh expects a file email.in with the IDs, and produces email.out.

Kind regards,

Re: Need Help with making a bash script

For your first problem:

today=`date "#+%d%m%Y"`
while read ipaddr
do
echo "$ipaddr REJECT $today"
done < blacklist_file > /tmp/new_file$$
mv /tmp/new_file$$ blacklist_file

Re: Need Help with making a bash script

Hey I apreciate all of the answers but these scripts are nice and
simple. They get the job done in one line with sed.

thanks again.

Assuming that you are documenting why you are blocking an address,
instead of the date as a comment, you might was to use a case number.
The case number would point to a record of the event that triggered the
blocking, with the appropriate log files snips, packet traces, machines
effected, ...

Thank you

I was thinking about putting the date in because I was going to clear
out IP's after a couple of months. Just in case it was a one time error
where they sent out infected email. The case number system sounds
interesting, would I need it for CYA for anything?
