Here's my script so far:

Code:
#!/bin/bash
for drv in {b..k};
do
           badblocks -v /dev/sd$drv > badblocks_$drv.out  &
done

wait

for logfile in badblocks_*.out
do
   echo "Logfile $logfile:"
   cat $logfile
   echo
done > all_badblocks.out

mail -s "Badblock Scan" me@mymail.uk < all_badblocks.out

Thanks for all the help, as you may have guessed, I've not done much bash scripting!
If your script is named blockchecker.sh
Code:
chmod +x blockchecker.sh
./blockchecker.sh &

You may, of course, prefer to send the files individually as the scans finish, so this might be better because your script will finish and the process will carry on in the background:-
Code:
#!/bin/bash
for drv in {b..k};
do
   ( badblocks -v /dev/sd$drv > badblocks_$drv.out ; \
     mail -s "Badblock Scan of $drv" me@mymail.uk < badblocks_$drv.out ) &
done


Is that any better?

Thanks Robin, that would be perfect.. Handy if I have different sized drives being tested. Smilie
