Read File Symbolic Links

Description

Find out if a file path is a symbolic link, and if so what it is linked to, via the system call readlink.

Symbolic links are a POSIX concept, not implemented on Windows but for most filesystems on Unix-alikes.

Usage

1
Sys.readlink(paths)

Arguments

paths

character vector of file paths. Tilde expansion is done: see path.expand.

Value

A character vector of the same length as paths. The entries are the path of the file linked to, "" if the path is not a symbolic link, and NA if there is an error (e.g., the path does not exist).

On platforms without the readlink system call, all elements are "".
