/opt/app/current is a symbolic link containing the relative target releases/v2.
Determine the base used to resolve the target.
What target is resolved?
A relative path stored in a symbolic link is resolved relative to the directory containing the link, not the process's current working directory.
Detailed explanation
Incorrect. The process current working directory is not the base for a relative symlink target.
Incorrect. The leading slash would make the path absolute and is not stored here.
Incorrect. This omits the app directory that contains the link.
Correct. /opt/app plus releases/v2 resolves to /opt/app/releases/v2.
Try it yourself
An example you can run in a temporary verification environment.
readlink /opt/app/currentExpected result
リンクに格納された相対文字列releases/v2を表示するKey points
- The link's parent is the base
- It is not based on cwd
- Distinguish stored text from resolved path
Notes
- Environment: GNU coreutils 9.x/Linux
- Command output formatting can vary slightly by distribution or tool version.
- Run the example in a temporary directory or process when possible.
