37. Which command is used to display all the files including hidden files in your current and its subdirectories?ls –Rls –als –aRls –l

The command used to display all the files including hidden files in your current directory and its subdirectories is ls -aR.

Here's the breakdown:

• ls is the list command and will show all files in the current directory.
• The -a option shows all files, including hidden ones. Hidden files in Unix-like systems (like Linux or MacOS) are any file or folder that starts with a ..
• The -R option makes the command recursive, meaning it will display files in all subdirectories of the current directory as well.

So, ls -aR will show all files, including hidden ones, in the current directory and all its subdirectories.
