Example:
This way you force users to log in with their regular accounts and sudo up to root, and you also prevent a user from being able to guess the root password and gain access.
Is sudo up to used as a phrasal verb there? sudo is the name of the command on Linux systems that gives you elevated rights over the system (actually, what it really does is it makes you the root user for a very brief period of time). And root is the default system administrator account on all Linux systems.
Answer
sudo:
is a program for Unix-like computer operating systems that allows users to run programs with the security privileges of another user, by default the superuser. (Wikipedia)
The root account is ‘above’ normal users, so to ‘sudo up to’ is another way of saying to elevate privileges.
In this case, ‘to sudo up’ is used as a phrasal verb, although it’s quite rare. Normally phrasal verbs are things like to ‘look down on’ or to ‘see to’, which are more common.
