rm command in linux/unix

1. Use the rm command to delete a file. List your directory after the command completes.

   
        rm new.config
        ls
        

2. cd to another subdirectory say, subdir2. List the directory to view its contents. Then use the "*" wildcard to remove all of the files. NOTE: using rm in this manner can be dangerous! If you are in the wrong directory, you'll remove files you didn't mean to remove. You may want to use the -i option to protect yourself from accidents.

   
        cd subdir2
        ls
        rm -i *
        ls
        

3. Get out of the subdir2 subdirectory by using the command cd .. Now try to use rm to remove a directory. What happens?

   
        cd ..
        rm subdir3
        

4. This time, include the -r option when you try to remove a directory. For example, try removing some subdirectory subdir3. What happens?

   
        rm -r subdir3
        ls
