+* `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;
+* `lein_not_task` – fixes wrong `lein` tasks like `lein rpl`;
+* `mkdir_p` – adds `-p` when you trying to create directory without parent;
 * `no_command` – fixes wrong console commands, for example `vom/vim`;
+* `python_command` – prepends `python` when you trying to run not executable/without `./` python script;
+* `rm_dir` – adds `-rf` when you trying to remove directory;
 * `sudo` – prepends `sudo` to previous command if it failed because of permissions;
