Curious? Xfce-4 terminal window. [Solved]

[jj 5117]

Using my non-admin account, as usual, I opened a separate terminal to SU and run "apt autoremove".
Everything seemed to go fine, and the normal prompt was presented. That is all that I did in that terminal window.
I clicked to close it, and it said, effectively, "a process is still running, do you want to kill it?"

After I closed it, I thought it was kinda weird. SU and Apt Autoremove was all that I had run in that terminal.

I thought that I would ask about it. Thank You.

When you open a Terminal, you are creating a bash process owned by your user.
When you su, you are creating another bash process owned by root.
Since there are two processes running and clicking the X only kills the foreground one, you get that message.
Better practice is to use exit to exit the root bash before you close the terminal.
In the scenario you are describing what you did won't cause any problems. There were no processes still running inside the user bash except the root bash.

[jj 5117]

THANKS! @timkb4cq
I hadn't noticed it doing that before. I wasn't too worried, I wondered if it signaled something. I appreciate it.

[fehlix]

Perhaps easier with using using sudo instead of running another bash as root:
E.g with

Code: Select all

sudo apt update && sudo apt full-upgrade

or

Code: Select all

sudo apt autoremove

b/c when those commadn finsh, you can close the the terminal as no other bash is running.
Also note: running just "su" to get a root-termina prompt

Code: Select all

su

will keep quite a number of environment vars pointing to user home.
E.g here demonstrate with my user "fehlix"

Code: Select all

root@mx234-386:/home/fehlix/Desktop# printenv | grep -E 'fehlix|1000' | sort
LOGNAME=fehlix
PWD=/home/fehlix/Desktop
USER=fehlix
XAUTHORITY=/home/fehlix/.Xauthority
XDG_CACHE_HOME=/home/fehlix/.cache
XDG_CONFIG_HOME=/home/fehlix/.config
XDG_DATA_DIRS=/usr/share/xfce4:/home/fehlix/.local/share/flatpak/exports/share:/var/lib/flatpak/exports/share:/usr/local/share:/usr/share
XDG_GREETER_DATA_DIR=/var/lib/lightdm/data/fehlix
XDG_RUNTIME_DIR=/run/user/1000

which can create lot off issues, in case you start from the su-root prompt a GUI app,
Look here what I got now, after running two apps:

Code: Select all

find ~ -user root -ls
   529842      4 -rw-r--r--   1 root     root          237 Jan 30 00:52 /home/fehlix/.config/MX-Linux/mx-packageinstaller.conf
   529915      4 -rw-r--r--   1 root     root          202 Jan 30 00:53 /home/fehlix/.config/MX-Linux/mx-repo-manager.conf

You suddenly have root-owned files within your home. In this case probably not big issue,
but can create a lot of issues if other files are involved.
Bottom line:
Better run just with "sudo" any terminal command, try to avoid root-terminal.

Hi @fehlix,

Sometime in the last couple of years, xfce terminal's sudo stopped accepting any password other than the current user, for sudo.
Using my non-admin account, my usual one, makes that a problem. I suppose that I could try another emulator for sudo-ing....

Thanks!

sudo requires to enter your users login password, which is your user password - not roots password.

[timkb4cq]

Is your non admin account in the sudoers group?

sudo isn't an xfce-terminal feature. It's a program, same as "ps" or "ls". Any terminal emulator you run is going to run the same "ps" and the same "ls" and the same "sudo". The passwords that sudo accepts are controlled through /etc/sudoers, as are the privileges that those passwords grant, so i can't imagine a situation where you'd want a password to work that wasn't the current user's password.

[jj 5117]

@DukeComposed
"sudo isn't an xfce-terminal feature" -- I am well aware of that, thank you. You don't seem to have heard me aright.

@timkb4cq hanks
"Is your non admin account in the sudoers group?" -- Thanks Tim! I'll try that out and see if it works the way that I would like.

Thanks, all!

[jj 5117]

Oops, missed one.

@fehlix

"sudo requires to enter your users login password, which is your user password - not roots password." -- Yes, and for that non-admin account, the user password does no good. At one time, while on a non-admin account, xfce would prompt for and accept the password of an admin account to sudo. Xfce terminal now takes only the password of the current user.

Thank you very much!
