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. Use is_file() to check for file (not directory) existence)

Usage

file_access(path, mode = "exists")

file_exists(path)

dir_exists(path)

link_exists(path)

Arguments

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")
