You need to list all files in a directory, including hidden files. Which command will achieve this?1.0 Marksls -lls -adir -hshow -hiddenlist -all

Break Down the Problem

1. Identify the presence of hidden files in a directory.
2. Determine the command-line option that will list all files, including hidden ones.
3. Evaluate the options provided.

Relevant Concepts

• In Unix-like operating systems, hidden files are typically files that start with a dot (.) and are not shown by default.
• The command ls is used to list directory contents, and options can modify its behavior.

Analysis and Detail

1. Option Breakdown:
   • ls -l: Lists files in long format but does not include hidden files.
   • ls -a: Lists all files, including hidden files (files starting with a dot).
   • ls -h: This option is used for human-readable file sizes and does not directly relate to listing hidden files.
   • The rest of the options: There are no valid commands among show, hiddenlist, or -all.

Verify and Summarize

Only the option ls -a specifically addresses the requirement to list hidden files. Therefore, the best choice to list all files in a directory, including hidden ones, is using the ls -a command.

Final Answer

The correct command to list all files, including hidden files, is:
ls -a
