k ∴

k is a zsh alternative to ls for more intuitive directory listings:

k is a zsh script / plugin to make directory listings more readable, adding a bit of color and some git status information on files and directories.

Via One Thing Well:

k’s output includes colour-coded markers showing the git status of repositories or individual files, ‘rotting dates’ which show older file modification dates in muted colours, and colour-coded filesize listings.

Some people use l as an alias for ls, hence the name k. Be sure to run k --help to see all of the available options.
