There is a unix command called repeat.
repeat 10 some_command
Basically repeats some command ten times. Is it available on Centos 6 and what package provides it?
Hello Matt try man watch All the best Paul

Hello Matt try man watch All the best Paul
What I am trying to do is:
http://www.redbarn.org/dns/ratelimits
repeat 10 dig @server-ip-address +short +tries=1 +time=1 your-zone.com a
Can I do that with watch?
ok I'd use a script and use sleep

No. But you can do it with 'seq':
for x in $(seq 1 10); do dig @server-ip-address +short +tries=1 +time=1 your-zone.com a; done

this works but at least with bash you can do it with brace expansion for x in {1..10}; do … ; done
it's a bashism but maybe more portable, e.g. OS-X has no seq no fork (for the seq) is necessary as well

True. Thing I like about seq is that it also takes an optional increment value which can be very handy at times.

$ echo {1..10..2}

C6's bash supports this; C5 sadly does not. But thank you for pointing this out to me as I was unaware of this form.

Is it _really_ that hard to type the explicit loop with test ([) and expr? These were builtins even in bourne shell eons ago.

It is not hard. I *tested* what I posted yesterday, and copied and pasted it into my email.

Sure it worked on the box where you tested it, but I think your version was at least bash-specific and something you'd need to know which version runs where if you use bourne shells anywhere. I'm not good at tracking that stuff, so I like backwards and cross-platform compatibility.

Oh, sure. Running CentOS 6.4, and yes, I use bash.

Here is the simplest possible solution, and exactly what I think the OP was looking for:

Yes, if you think that downloading/installing/maintaining yet another specialized program on every device that might need it is simpler than typing a couple of lines re-using knowledge that's been good for 20+ years.

I believe OSX has jot, which is what I used to use with FreeBSD. Fairly similar, and OSX does use bash so the expansion ought to work. Don't have a MAC or BSD box to test right now.

Would never have looked for it - for (( i=-; $i < 10; i++ )); do echo $i;done
I'm even more old-school with bourne syntax: i=0 while [ $i -lt 10 ] do echo $i i=expr `$i + 1` done
Just replace the 'echo $i' whit whatever command you want - or add it on the next line so you can see the iteration count too.

I was going to post the same information about finding out with "yum whatprovides". FWIW, repeat is a built-in command in tcsh. Maybe that's where you've seen it before.

You could use that with CentOS
$ csh -c "repeat 10 ..." $ tcsh -c "repeat 10 …"
$ rpm -qf /bin/tcsh tcsh-6.17-24.el6.x86_64

Someone has already mentioned tcsh, but this is also a builtin (syntactic operator like "while" or "for", actually) in zsh.
repeat 10 simple_command repeat 10 do list; of; commands; done repeat 10 { list; of; commands }
