Only the first -> is necessary. I would write it as

$server->{cmds}[$i]{status}

But i concur with your point, in general its easier to understand the -> style, as it reduces the possible meanings of $$ in your code (it has multiple meanings which depend on what follows, sometimes quite far after). In fact some people even avoid using bare scalar dereferencing on simple scalars just to avoid having $$ in their code. So they write ${$scalar_ref} instead of $$scalar_ref. (Im not in this camp personally).

[Discipulus]: i have a different opinion: automation is always worth: first i can use Perl (and this is good), then later you can reuse parts to automate others tasks. My $boss everytime say:'how much time you spend doing this?' So generally i present a perl solution
[Corion]: Discipulus: Yes, but the chart gives some limits on whether it's really worth spending time for saving your time. If you gain enjoyment, automating is still great, but it doesn't save time ;)
[Discipulus]: Corion are you would able to realize such thing? O_O
[Corion]: In the same vein I have a script that automates Firefox to enter some data into another system. It's not faster than the people using the script if they were to do it manually, but they prefer not having to check the data and not having typos when ...
[Corion]: ... entering the data
[Corion]: Discipulus: I don't know whether I could really do that, but the init process itself mostly launches other processes, and the whole startup is just following a path of dependencies and making sure they are all running. Which basically is what ...
