Questions tagged [ln]

Use this tag for questions related to the `ln` (link) command. The `ln` command is available in *nix OS to create links, allowing more than one filename to refer to the same file. Two types of links can be created using `ln`: symbolic links and hard links. Do not use this tag to refer to the natural base-e logarithm (furthermore base-e log is written "log" in most programming languages): use the [natural-logarithm] for that.

The ln (link) command is used in *nix OS to create links, allowing more than one filename to refer to the same file. Two types of links can be created using ln:

  1. Symbolic links: refer to a symbolic path indicating the abstract location of another file. The two file names need not be on the same file system. System call: symlink().
  2. Hard links: refer to the specific location of a physical file. The two file names must both be on the same file system. System call: link().

Note: For questions related to ln function which is used to calculate logarithms, please use the tag.
