Julia Filesystem.mv用法及代码示例

mv(src::AbstractString, dst::AbstractString; force::Bool=false)

将文件、链接或目录从 src 移动到 dst 。 force=true 将首先删除现有的 dst 。返回 dst 。

例子

julia> write("hello.txt", "world");

julia> mv("hello.txt", "goodbye.txt")
"goodbye.txt"

julia> "hello.txt" in readdir()
false

julia> readline("goodbye.txt")
"world"

julia> write("hello.txt", "world2");

julia> mv("hello.txt", "goodbye.txt")
ERROR: ArgumentError: 'goodbye.txt' exists. `force=true` is required to remove 'goodbye.txt' before moving.
