Which of the following commands will print the exit value of the previous command to the screen in bash?

In Bash, the special parameter `$?` holds the exit status of the last executed foreground command. An exit status of `0` generally indicates success, while any non-zero value signifies an error or abnormal termination, making `echo $?` the correct way to display it.

`echo $#` prints the number of positional parameters passed to a script or function, not the exit status of the last command.

`echo $exit` is incorrect because `exit` is a command used to terminate a shell, not a variable storing the exit status.

`echo $status` is not a standard Bash variable for exit status; `status` is used in some other shells like `csh` or `tcsh`.

`echo $&}}` is not valid Bash syntax for retrieving the exit status of a command.
