The best way to delete information
It’s dangerously straightforward to delete information with the rm command. Right here’s an instance. After you launch Terminal (in your /Functions/Utilities folder) sort cd ~/Desktop to navigate to the Desktop listing. To delete a file on the Desktop, sort rm filename, changing filename with the precise title of the file you need to delete. (When you’ve got a file title with areas, you might want to put the title in quotes: "For Instance.txt".) If you happen to had a file right here named MyFile.rtf that you just by no means, ever wished to see once more, you can run this command:
rm MyFile.rtf
Whenever you press Return, the file will go poof! The Mac doesn’t verify if you wish to delete the file. It will likely be gone, toast, historical past. You possibly can’t get it again.

However there’s a security web: it’s the -i (interactive) flag. So when you’re feeling cautious, you can run the above instructions with this flag as follows:
rm -i MyFile.rtfOr, within the case of deleting a number of information:
rm -i MyFile.rtf MyCV.rtf MyGreatAmericanNovel.rtf
In every case, urgent Return gained’t truly activate the rm command, as a result of the -i flag acts as a pause button. You’ll see the next in Terminal when operating these instructions:
IDG
To be able to proceed, you might want to sort sure, or just y. Within the case of a number of information, you’ll see one question for every file. Granted, it’s straightforward to get into the behavior of rapidly typing y, however the query is meant to make you cease and suppose very fastidiously about whether or not you actually need to delete that file.

IDG

The best way to delete all the pieces in a listing
The rm command has a strong possibility, -R (or -r), in any other case often known as the recursive possibility.

You enter the command as rm -R directoryname, the place you substitute directoryname for the title of the listing you need to delete. (When you’ve got a listing title with areas, you might want to put the title in quotes: "For Instance".)
For instance, let’s say you’ve a listing filled with archives, containing sub-directories and information. Deleting every merchandise individually from the Finder or the command line can take a very long time. So simply run the command like this:
rm -R Archives
Bear in mind, this deletion is closing. However you need to use the -i flag for cover:
rm -iR Archives
This may ask you to verify the deletion of every merchandise. This may be annoying, however until you’re actually positive you need to delete all these information, it’s in all probability finest to be secure.
