How do I get the target of a symlink?
RubySymlinkRuby Problem Overview
I have a string containing the file system path to an existing symlink. I want to get the path that this link points to.
Basically I want the same that I'd get through this bit of hackery:
s = "path/to/existing/symlink"
`ls -ld #{s}`.scan(/-> (.+)/).flatten.last
but I want to do it without shelling out.
Ruby Solutions
Solution 1 - Ruby
I think readlink is what you are looking for:
File.readlink("path/to/symlink")
Solution 2 - Ruby
require 'pathname'
Pathname.new("symlink").realpath
or readlink as others said
Solution 3 - Ruby
Or you can try:
File.realpath("symlink_path")
Which works for both symlinks and normal files.
