  Using dbg/2 [1]:

    # In dbg_pipes.exs
    __ENV__.file
    |> String.split("/", trim: true)
    |> List.last()
    |> File.exists?()
    |> dbg()
  

  This code prints:

    [dbg_pipes.exs:5: (file)]
    __ENV__.file #=> "/home/myuser/dbg_pipes.exs"
    |> String.split("/", trim: true) #=> ["home", "myuser", "dbg_pipes.exs"]
    |> List.last() #=> "dbg_pipes.exs"
    |> File.exists?() #=> true
