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, ~/ .bash_profile, ~/ .profile, ~/ .bash_login
- B. /etc/profile, ~/ .bash_profile
- C. /etc/profile, ~/ .bash_profile, ~/ .bash_login, ~/ .profile
- D. /etc/profile, ~/ .profile
Answer: C
Explanation:
Explanation
When 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.

Explanation
C (not A): Very often, it is not desirable that the root user on a client machine is also treated as root when accessing files on the NFS server. To this end, uid 0 is normally mapped to a different id: the so-called anonymous or nobody uid. This mode of operation (called 'root squashing') is the default, and can be turned off with no_root_squash.
E: In releases of nfs-utils up to and including 1.0.0, the async option was the default. In all releases after 1.0.0, sync is the default, and async must be explicitly requested if needed.
