 * `cd_parent` – changes `cd..` to `cd ..`;
+* `cp_omitting_directory` – adds `-a` when you `cp` directory;
 * `git_no_command` – fixes wrong git commands like `git brnch`;
 * `git_push` – adds `--set-upstream origin $branch` to previous failed `git push`;
+* `has_exists_script` – prepends `./` when script/binary exists;

+* `mkdir_p` – adds `-p` when you trying to create directory without parent;

 * `sudo` – prepends `sudo` to previous command if it failed because of permissions;
