What's the Trick Behind These Tricky Shell Commands?

What will be the output if you type the 'ls -l' command in a BASH session?

a) long listing of files and directories including details such as permissions, owner, size, and modification date

b) prints a list of all files and directories in the current directory

c) displays only hidden files and directories

Answer:

The correct answer is a) long listing of files and directories including details such as permissions, owner, size, and modification date.

When you type 'ls -l' in a BASH session, it will provide you with a long listing of files and directories in the current directory. This detailed listing includes information such as permissions, owner, size, and modification date of each file and directory. It allows you to get a comprehensive view of the contents within the directory.

If you selected option b) prints a list of all files and directories in the current directory, it is not entirely accurate as the 'ls -l' command specifically gives a long listing view, not just a simple list.

Similarly, option c) displays only hidden files and directories is incorrect as the 'ls -l' command does not specifically show only hidden files and directories unless specified with additional parameters.
