hostname range 1

[msatishkumar143]

Hi all,

I have a host range like this
a[1-3].it.{colo1,colo2,colo3}.yyy.com

are there any unix command which will get the output as .

a1.it.colo1.yyy.com
a2.it.colo1.yyy.com
a3.it.colo1.yyy.com
a1.it.colo2.yyy.com
a2.it.colo2.yyy.com
a3.it.colo2.yyy.com
...

and so on.

Thanks
Dinesh

If you have "[tt]seq[/tt]", you could do this...

seq 1 3 | while read INNER
do
    seq 1 3 | while read OUTER
    do
        print "a${OUTER}.it.colo${INNER}.yyy.com"
    done
done

If you don't have "[tt]seq[/tt]", this should work...

for INNER in 123
do
    for OUTER in 123
    do
        print "a${OUTER}.it.colo${INNER}.yyy.com"
    done
done

Oops, there should be spaces between the 1, 2, and 3.

In some shells you can just echo it in almost exactly the way you specified and it will be automatically expanded. I think this works in bash and ksh93, see this example in bash:

$ echo a{1..3}.it.{colo1,colo2,colo3}.yyy.com | xargs -n1
a1.it.colo1.yyy.com
a1.it.colo2.yyy.com
a1.it.colo3.yyy.com
a2.it.colo1.yyy.com
a2.it.colo2.yyy.com
a2.it.colo3.yyy.com
a3.it.colo1.yyy.com
a3.it.colo2.yyy.com
a3.it.colo3.yyy.com
$
