Hello, everyone.
And day more, I'm going to explain the difference between pseudo combat and it's you come at.
I use the pseudo command when I would like to run a single command with road privileges.
However, I need to be in the Suja or five or to be in a group and a soda were fired.
So let's do an example here.
For example, if I would like to display the content of the shadow file, the system will not allow
me to show that fire.
Because I don't have a clear mission to few to continue this fight.
So it's a mission tonight.
So since student is parked or is in a group in a room, it's in a rude group.
And the SUDA were fired.
So I can use this.
So do command in order to fuel that fire.
So I'm going to try pseudo first, then the command cat slash ATC slash shadow.
I hit enter.
Then I have to type the password a ginger and I can display the content of the shuttle file.
Same thing here for the if this command is here to enter.
I don't have any permission.
Permission denied.
So I'm going to use the pseudo command in order to use the F DESC command to enter, as we can see here
right now.
I can run the F this command when I use the SUDA comment.
Why?
Because student is in a group and the soldier were fired.
So the student has a preference is to run single command in the system with road privileges.
Now, let's move on to the next command.
The command issue is the issue is used to switch to another user.
So the S.
Is is the short for switch and you is the short for user.
But you can also switch to the route user by invoking the command with no parameter.
So let's do first drivers assembly as you dash.
Dan, Dan.
And the name of the user.
So an example here, if I would like to use the option dash or dash l or dash dash log and.
In order to watch, in order to start the shell as a log and share with the environment similar to a
real logging, what it means.
I'm going to open a new shell for users.
So I'm going to hit enter.
I'm going to try the password right now.
I have a new shell for user top.
I'm going to exit now.
If if I'm going to do.
Yes.
That is you without Desh.
Then the name of the user taught I to enter.
Won't you type the password, as we can see you?
We didn't all be like, can you share with the environment similar.
So I'm still in the shell of the student.
So if I'm going to type Alice.
I have permission denied because I don't have the privileges in order or the permission or those to
list or view the content of users.
So we have to pay attention to this point.
So it's the best way to use, as you do, dash in the name of the user.
And there is also another think.
If A right now I'm Muser student, if I would like to switch to a road user, I can type pseudo.
Then as you dash hit, enter now or choose her.
So I did.
I don't need like syncing, I swear.
I switched the user from a student to route.
I don't have to use the pseudo command.
I can't run any commands.
For example, ADC and Shadow as can see.
Now let's run also the F disk without a disk slash slash dev slash is there.
You can see here we can run the command without do comment to correct exit.
I also I can log in to the root user by typing insu then dash like that to enter the password.
Right now I what I did a switch from a student user to a road user for more information about the comment.
So do you.
Can't go to the main page and we can find more details and options also that we can use with pseudo
command.
Same thing for the ICU man issue and we can use run command with sub secured user on a group I.D. so
we can find also the options over here.
Thus, conclude our session.
Thank you.
And see you in the next lesson.
