質問 34
What is the first file executed by a bash login shell?
- A. /etc/profi le.alias
- B. /etc/bash
- C. -/profile
- D. -/.alias
- E. /etc/profile
正解: E
解説:
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.
