如何从 Julia 的工作目录中删除文件？

Question

如何从 Julia 的当前目录中删除文件？

R中是否有像file.remove()这样的直接函数？

Answer 1

是的，有rm。请参阅 Julia in-REPL 帮助（通过按 ? 访问）：

help?> rm
search: rm permute! normpath permutedims permutedims! PermutedDimsArray uperm operm gperm isperm powermod VecOrMat invperm invpermute! rem rem2pi argmin argmax promote promote_type promote_rule promote_shape

  rm(path::AbstractString; force::Bool=false, recursive::Bool=false)

  Delete the file, link, or empty directory at the given path. If force=true is passed, a non-existing path is not treated as error. If recursive=true is passed and the path is a directory, then all contents
  are removed recursively.

  Examples
  ≡≡≡≡≡≡≡≡≡≡

  julia> mkpath("my/test/dir");

  julia> rm("my", recursive=true)

  julia> rm("this_file_does_not_exist", force=true)

  julia> rm("this_file_does_not_exist")
  ERROR: IOError: unlink: no such file or directory (ENOENT)
  Stacktrace:
  [...]

所以你可以做rm(filename)。
