Try this:

for i in `seq 10` ; do <your command here> ; done

it will repeat <your command here> 10 times.

1@Phil: With Bash, it's not necessary to use seq. You can do for i in {1..10} or for ((i=1;i<=10;i++)) and it saves forking another external executable. – Paused until further notice. – 2010-08-17T19:08:37.543

@Dennis: Sure, you've right, but this job doesn't seem a time-critical task. – cYrus – 2010-08-17T19:15:54.970

If the point is to learn shell programming, see cYrus's answer.

If the point is to generate a password, many distributions ship with pwgen.
