How can I see the size of each file in a particular directory in the terminal?

Question

When using the terminal, is there a command that allows you to see the size of each individual file in a particular directory?

Answer 1

On Linux/Unix, use

• ls -lk (for size in kilobyte) or
• ls -lh (for easier readable approximate file sizes, like 12M or 2G).

ls -l will show size in blocks, which might not be that useful.

Answer 2

Use ls -l to list all files with their details on OS X and Linux, or dir on Windows.
