Bash is invoked as an interactive login shell. What is the order in which the bash configuration files are read, assuming that all the files exist in their correct location and are readable?
-
A
/etc/profile, ~/ .profile
-
B
/etc/profile, ~/ .bash_profile

C
/etc/profile, ~/ .bash_profile, ~/ .bash_login, ~/ .profile
-
D
/etc/profile, ~/ .bash_profile, ~/ .profile, ~/ .bash_login
Reveal answer details
Close answer details
Correct answerC
ExplanationWhen Bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior. When a login shell exits, Bash reads and executes commands from the file ~/.bash_logout, if it exists.

-
E

-
F
The User private Group scheme is enabled by default in Oracle Linux.
Reveal answer details
Close answer details
Correct answersD, E, F
ExplanationDF (not A): By default, Oracle Linux implements the user private group (UPG) scheme where adding a user account also creates a corresponding UPG with the same name as the user, and of which the user is the only member. E: When setgid permission is applied to a directory, files that were created in this directory belong to the group to which the directory belongs, not the group to which the creating process belongs. Any user who has write and execute permissions in the directory can create a file there. However, the file belongs to the group that owns the directory, not to the user's group ownership.
