Which shell is described as sh-compatible and stores command history in a file called the bash history?

• A. Cipher.exe
• B. Bash
• C. Meterpreter shell
• D. fsutil

Answer: (B)

Shells that are sh-compatible follow the Bourne shell syntax, which keeps scripts portable across Unix-like systems. Bash, the Bourne Again SHell, is designed to be compatible with sh while adding enhancements like command-line editing, scripting features, and a history mechanism. It saves previously entered commands to a history file in the user's home directory, typically ~/.bash_history, so you can recall and reuse commands in future sessions. The other options are not Unix-like shells with this behavior: Cipher.exe is a Windows cryptographic utility, Meterpreter shell is a post-exploitation payload rather than a standard Unix shell with a history file, and fsutil is a Windows file system utility. Therefore, Bash is the correct match.
