-i, --inode

Print the index number of each file.

-l

Use a long listing format.

-r, --reverse

Reverse order while sorting.

-R, --recursive

-s, --size

Print size of each file, in blocks.

-S

Define aliases for directory listing

if type -P 'eza' >'/dev/null' 2>&1; then              # eza
  alias ls="eza --classify --time-style='long-iso'"
  alias ll='ls --git --group --header --long'
  alias l='ll --all --all'
else
  if ls --context >'/dev/null' 2>&1; then             # GNU ls version
    alias ls="ls --classify --color --time-style='long-iso'"

    if type -P 'dircolors' >'/dev/null' 2>&1; then
      eval "$(dircolors -b)"
    fi
  else                                                # other ls versions
    alias ls="ls -D '%F %T' -F -G"
  fi

  alias ll='ls -h -l'
  alias l='ll -a'
fi

alias lr='l -R'
alias lt="l -r -s 'time'"
