file_access: Query for existence and access permissions

In fs: Cross-Platform File System Operations Based on 'libuv'

Query for existence and access permissions

Description

file_exists(path) is a shortcut for file_access(x, "exists"); dir_exists(path) and link_exists(path) are similar but also check that the path is a directory or link, respectively. (file_exists(path) returns TRUE if path exists and it is a directory.)

Usage

file_access(path, mode = "exists")

file_exists(path)

dir_exists(path)

link_exists(path)

Arguments

path	A character vector of one or more paths.
mode	A character vector containing one or more of 'exists', 'read', 'write', 'execute'.

Details

Cross-compatibility warning: There is no executable bit on Windows. Checking a file for mode 'execute' on Windows, e.g. file_access(x, "execute") will always return TRUE.

Value

A logical vector, with names corresponding to the input path.

Examples

file_access("/")
file_access("/", "read")
file_access("/", "write")

file_exists("WOMBATS")
