In a UNIX machine, what is the difference between su
and su -
?
Is there even a difference?
I know that su -
is the standard.

Well the su - "Username" or su -1 "username" or su --login "username" (all the same) will give you a login screen, and change paths, home directory, etc..
The su "username" command only chances user, and not home directories (this does not apply to "su no username" because you login has Root / SuperUser, and you will given the root's default environment, including path to executable file changes. You will also land into the root's home directory.) so to answer your question to make sure they are in the right place with the right user?

4Did you look at
man su
? If so, what part of its explanation did you find confusing? – John1024 – 2018-06-03T20:39:26.390I also would not say that
su -
is the standard. I'd assume that most people who usesu
do so simply for the root-level permission . . . – Jason Bassford Supports Monica – 2018-06-03T20:41:47.2471@Jhon1024, I did not think to read the
man su
file. Maybe I should have. – Anonymous – 2018-06-04T21:20:51.277Possible duplicate: https://unix.stackexchange.com/questions/7013/why-do-we-use-su-and-not-just-su
