Delete On Mac
One of the most basic computer functions — deleting files and folders — is also one of the most essential. If you never get rid of anything, soon enough all those extra gigabytes will take a toll on your Mac's processing power, RAM, and hard drive, not to mention your digital life will resemble a dreadful episode of Hoarders. 
The keyboard shortcut Command-Option-Shift-Delete empties the trash while bypassing the confirmation dialog window. If that four-button keyboard shortcut is too cumbersome or difficult to remember.
COMMAND + OPTION + ESCAPE is the CONTROL + ALT + DELETE Equivalent on Mac Hitting Command + Option + Escape on a Mac is basically the same thing as hitting Control + Alt + Delete on a Windows PC. This is the closest single equivalent there is, in that it ends program process whether they are stuck or not, basically forcing them to quit.
Secure Delete Files with Mac Terminal. For the sake of brevity, Mac Terminal can simply be defined.
So deleting files is good and healthy. But how do you do that? Most people right-click on what they need gone and choose Move to Trash from the menu or use the File option in the menu bar. Others employ the ⌘ + Delete shortcut, which works across the system (even within dialog windows). Experts, however, often find themselves defaulting to the command line delete directory feature. Let's see how and why you should learn it too.
How to remove directory with TerminalOpen Launchpad (by clicking its Dock icon, using the trackpad gesture, or searching for it in Spotlight), then click and hold any app icon until the icons start shaking. Click the 'X' button next.
Since macOS is a Unix-based system, nearly all system tasks you do every day with the help of its graphic interface can also be performed via the command line tool called Terminal.
Why delete file command line feature is importantWith regards to delete file or delete folder command line functionality, Terminal lets you:
Effortlessly erase one or multiple files, folders, and apps, bypassing any error messages you can get when you go the traditional route.
Remove files from Trash, including ones you can't delete by simply emptying the trash.
Get rid of files that are invisible to you within Finder (usually system or root files, for example, .htaccess).
Delete files and folders in cases when Finder is unresponsive.

Note: The Mac command line delete file feature is final and irreversible. While it lets you avoid any error messages, it also removes the files completely, without any possibility of retrieving them later on.
Tip: Delete unneeded system files on MacSome files are hard to delete in a normal way because they sit deeply in system folders. These are such files as logs, broken downloads, caches, remains of old apps, etc. Still, deleting them could give your Mac an extra boost — that's because they are outdated and clutter your macOS.
To dig these files out, try a free version of CleanMyMac X. Among other things, this app has an impressive System Junk detector. When you download CleanMyMac X (this free version is notarized by Apple), you need to click on System Junk.
Just take a loot at the sheer amount of files it unearthed. To delete them, click on Clean.
How to use delete file command line featureRemoving files from your Mac forever using Terminal is deceptively simple: just use the rm command followed by the name of the file. Here's how it works in practice:
Launch Terminal from your Utilities folder in Applications.
Check which directory you're in by typing ls -la
Then navigate down a directory with cd [directoryname] or up a directory with cd ./
When you're in the same directory as the file you want to delete, type rm [filename.extension]
If you want to delete multiple files at once, list them all, but make sure there's a space between each one.
Press Enter to execute the command.
Now all the files you specified after rm are gone for good. Navigate directories in your Mac and repeat the process as many times as you want. 
Surprised there was no confirmation before your files were deleted? Luckily there's a way to add one as a safeguard for not deleting the wrong file by accident. Just use -i after the rm but before the first filename, like this: rm -i [filename.extension]. Terminal will then ask you whether you're sure you want to delete the file. Reply y or yes followed by Enter and the file will be gone. This also works for multiple files, but you'll have to confirm the removal of each one separately.

How to make command line delete directoryFifa for mac os x torrent. Surprisingly, you can't delete a folder using the rm command because it has its own: rmdir.

Otherwise, rmdir works exactly the same as rm:
Navigate to the appropriate directory using Terminal.
Type rmdir [directoryname]
Hit Enter.
Sadly, you can't use the -i hack when you're deleting folders, so be extra careful! 
Another thing to keep in mind is that rmdir only deletes the directory, but can't delete any files or folders located within that directory.
To delete a folder with everything in it, you need to use rm -r followed by the folder's name. Using -i to create a warning here is possible and done like this: rm -ir [foldername].
When it's too difficult to find a folder or file via Terminal, but you can detect them in Finder, simply drag and drop the file onto the Terminal window to generate its path. 

Delete large and old folders using CleanMyMac X As it happens with folders, they are easy to mess up and lose track of. That's why many apps provide an alternative interface for searching and deleting files which is more flexible than the Finder. For example, using CleanMyMac X (the app we've mentioned above) you can find massive folders that might have been evading you. You also can filter them by file type and other criteria.
The latest released version of this tool looks like this:
This app by developer MacPaw is available for a free download here. Using this app, files are removed for good, and as far as we know, it's irreversible.
Other ways to delete files and folders on Mac The shortcut combination
We are sure you know how to drag to your files to the Trash. But here is an alternative way which deletes files at once, bypassing the Trash. There's one less step involved (you don't have to empty the bin). And you cannot reverse this action. 
Select a file, and press [Option + ⌘ + Delete]
Delete hidden folders on Mac

Some folders on your Mac are made invisible to protect them from accidental deletion. They are system and support files you would ignore most of the time. But what if a folder seems empty but still takes up space? You can apply another shortcut combination to highlight these unseen objects. Then, you can delete them at your own risk.
To highlight hidden folders: [Press Shift + ⌘ + . dot key]
This best works if you open some system folder, like Library
Again, delete these folders only if you are sure what they are.

To use a keyboard shortcut, press and hold one or more modifier keys and then press the last key of the shortcut. For example, to use Command-C (copy), press and hold the Command key, then the C key, then release both keys. Mac menus and keyboards often use symbols for certain keys, including modifier keys:

On keyboards made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command.
Some keys on some Apple keyboards have special symbols and functions, such as for display brightness , keyboard brightness , Mission Control, and more. If these functions aren't available on your keyboard, you might be able to reproduce some of them by creating your own keyboard shortcuts. To use these keys as F1, F2, F3, or other standard function keys, combine them with the Fn key.
