Shell – Running chsh does not change shell

If you want to execute zsh instead of bash, just replace /usr/local/bin/bash by the path to the zsh executable. Note that this snippet is specific to csh; if your login shell is not (t)csh, this code in ~/.login won't do anything for you.

As for why the snippet was written that way, you'd have to ask the person who wrote it. [Checks who that was.] Oh. Well, if you just do exec /usr/local/bin/bash then you won't be starting a login shell, so your .profile won't be executed. But this could be resolved in a simpler way by executing /usr/local/bin/bash --login.

Now, if your login shell is not csh, you'll want a different snippet around exec. In Bourne-style shells, including zsh:

if [ -x ~/bin/zsh ]; then exec ~/bin/zsh; fi

Make that exec ~/bin/zsh -l if you want the new instance of zsh to read your ~/.zprofile. Note that if you do that, the snippet above must be in your .profile or .bash_profile; if your login shell is zsh, don't put the snippet in your .zprofile, or else make very sure that the new instance of zsh isn't going to call that exec again.

Even though these appliance type products are based on Linux it's generally a good idea not to try and customize them as though they're Linux boxes. They typically are missing most of the tools and are usually stripped down in various ways which can make this dangerous.

I've had experience with both Netgear's ReadyNAS box as well as the Thecus boxes and this has always been the case with both these types of products. You might want to consider doing a factory restore to get this back normal instead of hacking it your self.

You'll have to reconfigure the box but this is usually just setting the IP back up and potentially some user account creation.

I direct you to the actual pages from Synology that cover how to accomplish this:
