Linux Foundation Certified System Administrator (LFCS) — Question 85

Which of the following commands is used to change options and positional parameters for a running Bash?

Answer options

• A. history
• B. set
• C. bashconf
• D. setsh
• E. envsetup

Correct answer: B

Explanation

The correct answer is B, as the 'set' command in Bash is specifically designed to change shell options and positional parameters. The other options do not perform this function: 'history' displays command history, 'bashconf' and 'setsh' are not standard Bash commands, and 'envsetup' is not related to changing options in a running Bash session.
