fs (version 1.3.1)

dir_ls: List files

Description

dir_ls() is equivalent to the ls command. It returns filenames as a named fs_path character vector. The names are equivalent to the values, which is useful for passing onto functions like purrr::map_dfr().

dir_info() is equivalent to ls -l and a shortcut for file_info(dir_ls()).

dir_map() applies a function fun() to each entry in the path and returns the result in a list.

dir_walk() calls fun for its side-effect and returns the input path.

Usage

dir_ls(path = ".", all = FALSE, recurse = FALSE, type = "any",
  glob = NULL, regexp = NULL, invert = FALSE, fail = TRUE, ...,
  recursive)
dir_map(path = ".", fun, all = FALSE, recurse = FALSE,
  type = "any", fail = TRUE)
dir_walk(path = ".", fun, all = FALSE, recurse = FALSE,
  type = "any", fail = TRUE)
dir_info(path = ".", all = FALSE, recurse = FALSE, type = "any",
  regexp = NULL, glob = NULL, fail = TRUE, ...)

Arguments

path

A character vector of one or more paths.

all

If TRUE hidden files are also returned.

recurse

If TRUE recurse fully, if a positive number the number of levels to recurse.

type

File type(s) to return, one or more of "any", "file", "directory", "symlink", "FIFO", "socket", "character_device" or "block_device".

glob

A wildcard aka globbing pattern (e.g. *.csv) passed on to grep() to filter paths.

regexp

A regular expression (e.g. [.]csv$) passed on to grep() to filter paths.

invert

If TRUE return files which do not match

fail

Should the call fail (the default) or warn if a file cannot be accessed.

...

Additional arguments passed to grep.

recursive

(Deprecated) If TRUE recurse fully.

fun

A function, taking one parameter, the current path entry.

Examples

# NOT RUN {
dir_ls(R.home("share"), type = "directory")

# Create a shorter link
link_create(system.file(package = "base"), "base")

dir_ls("base", recurse = TRUE, glob = "*.R")

dir_map("base", identity)

dir_walk("base", str)

dir_info("base")

# Cleanup
link_delete("base")
# }
