The correct answer is A. .bash_history.
When a user logs into a Linux system, Bash is typically the default shell that is loaded. Bash is a command-line interpreter that allows users to enter commands and execute them. Bash also stores a record of all commands entered in the past, in what is known as the Bash history.
The Bash history is stored in a file called .bash_history, which is located in the user's home directory. The filename starts with a period, indicating that it is a hidden file. Hidden files are not normally displayed when using the ls command, unless the -a (or --all) option is used.
To view the contents of the .bash_history file, the user can simply type the command:
shell$ cat ~/.bash_history This will display a list of all commands that have been entered by the user in the past.
It is important to note that the Bash history is not updated in real-time. Instead, it is updated when the user logs out of the system or when the Bash shell is closed. This means that if a user enters a command and then immediately logs out, the command may not be saved in the .bash_history file.
In conclusion, the correct file name for storing Bash history in the user's home directory is .bash_history (option A).
