Answer 1

使用键盘快捷键:Ctrl + L.

使用Julia的REPL shell模式:

julia> ; # upon typing ;, the prompt changes (in place) to: shell>

shell> clear    # unix

shell> cmd /c cls    # windows

如果您需要一个功能,您可以使用该run功能:

julia> ? # upon typing ?, the prompt changes (in place) to: help>

help?> run
INFO: Loading help data...
Base.run(command)

   Run a command object, constructed with backticks. Throws an error
   if anything goes wrong, including the process exiting with a non-
   zero status.

julia> using Compat: @static, is_unix    # `Pkg.add("Compat")` if not installed.

julia> clear() = run(@static is_unix() ? `clear` : `cmd /c cls`)
clear (generic function with 1 method)

julia> clear()

这适用于平台和版本无关的方式(在Windows和Linux中测试,Julia版本0.3.12,0.4.5和0.5.+).
