How is this possible?

Hi all

im learning how Linux works at school
its not that easy but im learning fast

i have a question

how come if i start Linux at school and use the Arrow Up key on my keyboard i see commands that i never before used but i know the other kids did like one task was to make a dictionary with your name and if i press the arrow up key i see all my classmates commands they used.

and i wanted to do the homework my teacher gave us and find out its already done all the task are done on my Linux program (we are using VM Ware player)

its like my Linux save other classmates work or something ?

If the vm has been used by other people and you all log in as the same user then their commands will be stored in the file ~/.bash_history unless it has been cleared.

The . at the beginning of the file name is how Linux hides files.
