server groups in a single hostfile?

[Xizhen Du]

Hi All,

Does pssh support that we can define several server groups in a single host file?

'@group_a' has servers : host-a1 host-a2 host-a3... etc..

'@group_b' has servers : host-b1 host-b2 host-b3... etc..

if so we can maintain 1 single hostfile for all hosts we have, quite like tentakel if you have used it before.

expected that we can run commands for some a group only, something like: pssh -g @group_a "cmds"

Please let me  know if I missed something.

Thanks,

Du

No, but you can easily use multiple host files, one for each group. If
you want to use multiple groups, you can use the -h option multiple
times.
