When you're logged in to your Mac using an administrator account, you can use the
sudo command in the Terminal app to execute commands as a different user, such as the root user. After you enter the command, Terminal asks you to enter your account password. If you forgot your password or your account doesn't have a password, add or change your password in Users & Groups preferences. You can then execute sudo Predictive text app for mac. commands in Terminal.
Aug 19, 2019 Mac laptops made in the last few years have an annoying/convenient feature. Open one up, and it powers on. MacBooks have woken from sleep when you open. Here's one way to do it using a pipe between commands. I verified that when I use the arguments in the commented out line that the file gets created by the super user.
Terminal doesn't show the password as you type. If you enter the wrong password or a blank password, the command isn't executed and Terminal asks you to try again.
In some flavors of Unix, you feel as if you've been cast into an alternate universe when you open a terminal window and work on the command line. https://keenbands188.weebly.com/mac-automatic-key-presser-app.html. But with OS X and its Darwin core, there's often an elegant integration between the two. In this how-to I'll show you how to launch an OS X app from the command line with the open command.

Jun 24, 2010 sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts In many systems this terminal command may work better: sudo open -t /etc/hosts When you run this command from a command line (in a Terminal window), you’ll be prompted for a password.
Launch An App From Terminal Mac Sudo To Another
[Note: A little bit of prior UNIX experience will be helpful here.]
First off, I will admit this technique is fairly geeky. In my [Mac] OS X career, I've only used this trick a handful of times. https://keenbands188.weebly.com/mac-os-1012-fax-software.html. However, it's so darn cool and charming that one just aches to use it at any opportunity.
Actually, upon reflection, there are some useful scenarios for this technique.
The Man Page
The terminal app is in the Utilities folder—which is found the Applications folder. Launch it now. The BSD UNIX command we'll be using is open. Below is the manual page ('man' for short), shown by typing:
I've printed most of the man page for the open command here for your perusal, but I'm not going to explore every argument. And feel free to jump right to the examples below to whet your appetite.

For this limited how-to, one interesting way to use the open command in this context is to use the [-a] option. Some other useful variations and arguments are in the examples below.
Typical Examples
Here are some short and sweet examples of the open command with the -a, -e, and -t arguments. They're easy to try. [If you don't have BBEdit installed, use any other favorite a text editor in /Applications.]
Open Doors
These are just a few of the cool things you can do on the command line with the open command. To keep things simple, I haven't delved into creating a search path or other Unix tricks like aliases. All that's been left for you to explore on your own.
I think this is one of the neatest tricks in OS X.
