    On Ubuntu 20.04.3 LTS, I use gap [1] (GAP - Groups, Algorithms, Programming - a System for Computational Discrete Algebra) to run the following script:

    $ cat gap-test.g
    Display(SmallGroup(8,1));
    QUIT;

    $ gap gap-test.g

    If I change the script into the following, i.e., use `quit;` as the last command:

    $ cat gap-test.g
    Display(SmallGroup(8,1));
    quit;

    In this case, the test result is as follows:

    $ gap gap-test.g

    As you can see, gap doesn't quit its running process even after all the commands have been completed. I'm very confused on this behavior. Any hints will be highly appreciated.

    Thank you. I understand the difference between them:

    1. quit

    type 'quit;' to quit to outer loop

    2. In manual, the following description is used:

    6.7.1
    QUIT
    . QUIT
    (global variable)
    An emergency way to leave GAP is to enter QUIT at any gap> or brk> or
    brk_nn > prompt.

    Thank you. I understand the difference between them:

    Apparently, you don't "understand the difference between" QUIT and quit.

    And, you certainly don't understand the scope of the help you can
    get in comp.unix.shell. Your question has nothing to do with
    the unix shell, and, if you need clarification on the differences
    between commands that a specific application supports, you should
    find a forum that discusses /that application/, or use /that
    application's/ FAQ/documentation/contacts.
