Bug report

• [ x] ran brew update and can still reproduce the problem?
• [ x] ran brew doctor, fixed all issues and can still reproduce the problem?
• [ x] ran brew config and brew doctor and included their output with your issue?

What you were trying to do (and why)

Obtaining long form output of all installed packages and casks.

What happened (include command output)

brew list -l

What you expected to happen

1. brew help list says “If the output is to a terminal, a total sum for all the file sizes is printed before the long listing.” There wasn't one.

2. Casks are printed in an inconsistent short format. I can see that brew cask help list shows no “long format” for casks, so I can see how this might have happened during the recent changes to merge casks into formulae.

Step-by-step reproduction instructions (by running brew commands)

brew list -l

Output of brew config and brew doctor commands

(Note, brew doctor says there are updated command line tools, even if I update them. Maybe it assumes I'm on latest mac OS?)

Options --cask and -l are mutually exclusive. This is why you got short output for casks
So if you want only formulae, you should specify --formulae

Thanks, but I didn't specify --cask. This is a report about the default output with just -l.
