Question

Decipher the results of ls -l. (Choose all that apply)

Option 1: This is a directory
Option 2: Owner can read, write and execute files
Option 3: This is a regular file
Option 4: None of the above

Answer 1

The results of 'ls -l' can determine if an item is a directory, a regular file, or if the owner can read, write, and execute files. The first character indicates if it's a directory (d) or a file (-), while permissions such as 'rwx' show the access level for the owner.

Step-by-step explanation:

To decipher the results of ls -l in the context of Unix or Linux file systems, we should first understand what the ls -l command does. It lists files and directories with detailed information including permissions, number of links, owner, group, size, and modification date. Each entry starts with 10 characters that describe the type of the file and the permissions for the owner, the group, and others.

Here are the possible options described in the question:

• Option 1: This is a directory - If the first character of the permissions listing is a 'd', it signifies a directory.
• Option 2: Owner can read, write and execute files - If the permissions listing shows 'rwx' (read, write, execute) for the owner, then the owner has full permissions on that particular file or directory.
• Option 3: This is a regular file - If the first character is a '-', it designates a regular file.
• Option 4: None of the above - This would apply if the entry does not match any of the criteria listed in options 1-3.

Based on the options provided, you would need to see the actual output of ls -l to determine which options apply.
