### 1.2 Technical Details

When `dired-x.el` is loaded, some standard Dired functions from `dired.el` and `dired-aux.el` offer additional features. `dired-add-entry` obeys Dired Omit mode (see Omitting Files in Dired), if it is active. `dired-find-buffer-nocreate` and `dired-initial-position` respect the value of `dired-find-subdir` (see Miscellaneous Commands). `dired-clean-up-after-deletion` respects the value of `dired-clean-up-buffers-too`. `dired-read-shell-command` uses `dired-guess-shell-command` (see Shell Command Guessing) to offer a smarter default command.
