- A. /etc/profile
- B. -/.alias
- C. /etc/bash
- D. /etc/profi le.alias
- E. -/profile
Answer: A
Explanation:
https://www.gnu.org/software/bash/manual/html_node/Bash-Startup-Files.html 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.
