R: List files

dir_ls {fs}

R Documentation

List files

Description

dir_ls() is equivalent to the ls command. It returns filenames as a fs_path character vector.

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, recursive = FALSE, type = "any",
  glob = NULL, regexp = NULL, invert = FALSE, fail = TRUE, ...)

dir_map(path = ".", fun, all = FALSE, recursive = FALSE,
  type = "any", fail = TRUE)

dir_walk(path = ".", fun, all = FALSE, recursive = FALSE,
  type = "any", fail = TRUE)

dir_info(path = ".", all = FALSE, recursive = 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.
`recursive`	Should directories be listed recursively? the filenames.
`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.
`fun`	A function, taking one parameter, the current path entry.

Examples


dir_ls(R.home("share"), type = "directory")

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

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

dir_map("base", identity)

dir_walk("base", str)

dir_info("base")

# Cleanup
link_delete("base")
