What does the 'd' at the start of the output indicate?

In the context of file permissions in Linux, a 'd' at the start of the output indicates that the item is a directory.

File Permission Format:

When you use commands like ls -l, the output shows file permissions in a format like this:

drwxr-xr-x

• The first character:
  • d: Indicates a directory.
  • -: Indicates a regular file.
  • Other characters may represent special file types (e.g., l for symbolic links).

Example:

If you see:

drwxr-xr-x 2 user group 4096 Jan 1 12:00 my_directory

This means "my_directory" is a directory with specific permissions.
