what does su -l do...and why would you have to sudo it
 

hi guys,

saw a video where the instructor wanted to login as root

he went...

sudo su -l

i see the -l option is -l, --login
Start the shell as a login shell with an environment similar
to a real login:

but i dont understand the significance of this...why couldnt you just go
su
login

You could but then you're pressing more buttons which takes time and time = money.

It is possible that the root account on the system being used was locked (ie, did not have a password set) so `sudo` is needed for the non-root user's password to be accepted.

Also, just using `su` would not source the root account's shell profile (~/.bash_profile) or /etc/bash.bashrc and any application settings in /etc/profile.d/*.sh
