How is it possible to aggregate memory usage of a Linux process and all its children in human readable format?
I tried this link and even using cat /proc/$pid/status but the latter had 18GB of VirtualMemory for chrome on my machine which only has 12GB of RAM (I know it is virtual and can be higher than physical RAM amount). But I need to know the physical memory usage of all chrome instances at once and at the moment.
I tried finding a similar question and did but there's a caveat though, older questions use --no-cert-check option which is removed due to security reasons and I don't know the exact fingerprint for the server as it will change from time to time. I need to pass two inputs to the openconnect command using something like echo -e "arg1\narg2" but was not successful.
How can I do it? (below is the command I used):
echo -e "yes\nmypassword" | openconnect serveraddress --user="myuser" --passwd-on-stdin
I can't connect to ProtonVPN using its official client from pypi on my Ubuntu 20.04 but on the same WiFi and using the same DNS (8.8.8.8) and its android app I can seamlessly connect.
I don't have a clue where the underlying problem might be.
The errors it gives me is as follows:
[!] There was an error connecting to the ProtonVPN API.
[!] Please make sure your connection is working properly!
I have a Asus laptop with Ubuntu 16.04, It has a function shortcut (fn+f7) which I used to turn off the display.
I connected it to an external display via HDMI, removed the cable, shut it down. but now after a fresh boot It locks my account instead and not turning the display off!
Any idea or suggestion is appreciated.
I have an Ubuntu 16.04 on Asus K55VD and pressing Fn+F1 to put it to sleep takes too long (up to 10 or 15 seconds) while running systemctl suspend will normally take less than 5 seconds.
I successfully run the command ping github.com. Output is like:

I'm using Ubuntu 16.04.2 LTS and have done some customization to unity like changing wallpaper, icon sizes and so. How can I back it up and restore it in some other machine, to be precise which file(s) should I copy?
The things I want to backup:
Albeit I can summarize it to everything I've changed through unity-tweak-tool.
I have Ubuntu 16.04 LTS and when I run something in terminal like md5sum it waits for my input and I enter something like Hello but when I press CTRL+D it does not terminate and I have to press CTRL+D for the second time to terminate that! why?
I could not find the solution but after installing Ubuntu 16.04.2 LTS the problem no longer exists!
I have a 1TB Transcend external hdd (inner chip is WDC_WD10JPVX-22JC3T0_WD-WX11A15R3AC8) and when I try to safely remove it either from file manager or even from command line with udisksctl unmount -b /dev/sdb1 and then udisksctl power-off -b /dev/sdb1, it immediately pops up again and won't power off.
I'm using Ubuntu 16.04.1 LTS.
These are some output after running udisksctl unmount -b /dev/sdb1 and then udisksctl power-off -b /dev/sdb:
