When execute system('hostname -s') -command in matlab, process go to linux command line and in linux command line making exit command, process will go back to matlab command line with hostname.
Example run:
>> system('hostname -s')
[j...al@oulng208 users3/j...al]$exit
exit
oulng208
ans =
0
>>
Why matlab goes to linux command line? It should stay in matlab.

What do you mean? The purpose of the system function is to call the OS command line.

If you want to capture the output to a Matlab variable, you should use the second output:
[status,response]=system('hostname -s');
I don't have Matlab installed on my Ubuntu VM, but this works in Octave, so it should do the trick.

You have a BASH_ENV or equivalent for your shell, that is triggering interactive execution for the non-interactive case.
Hypothetically there could also be issues if you have SHELL environment variable set to include flags that should not be set for non-interactive work.
