If there is any possibility to use the parameters in zsh aliases? Something like this:
alias ssh_nokia=\"ssh root@\"
Usag
In your particular case edit ~/.ssh/config (See Dave's answer below), or use:
alias ssh_nokia='ssh -l root'
Generally
ssh_nokia() { ssh root@"$@" }
is equivalent to alias (will produce ssh root@1stparam 2ndparam 3rdparam …).
ssh root@1stparam 2ndparam 3rdparam …
