Opening C File For Editing In Terminal Mac

I am currently working on mac but what I do when I want to create a file, editing it and just saving it is I type in vim in the terminal, vim is a texteditor incorporated in the terminal. So if you just type in vim you would see the text editor. But if you type for instance vim example.txt you open vim and from then on you are working in the file you created. The file, if I am correctly, does not get saved until you say so. So by pressing 's' you enter the edit mode of vim. Allowing you to put text in the file. If you want to save just enter escape followed by ':w', meaning you are saving the file with the name you have it to it, so for this example it would be example.txt.
Open ~/Desktop/filename.mp4 Edit: as per Johnny Drama's comment below, if you want to be able to open files in a certain application, put -a followed by the application's name in quotes between open and the file. Example: open -a 'QuickTime Player' ~/Desktop/filename.mp4 If you need further information about the open command, type man open. To open your.profile file, for example, start the Terminal application (searching for ‘terminal’ using Spotlight and clicking on the Terminal application is an open -a TextEdit.profile. Make your changes to the file and save it and you’re done. One compulsory note of caution: hidden files are often hidden.
After you saved it, everything you type after pressing escape is showed left down in the screen, simple type ':q' to quite it. If you realise you do not really want to save the file you can just type ':q!' And if you were currently in the editing mode, meaning you were typing something, you just press escape once followed by ':q!' So short summary: vim example.txt (opens the editor if saved it will use the given name) s (will enable edit mode, you can write stuff) escape (when you want to stop editing):w (save the file):q (quit the file, only usable when saved!):q! (discard the save and just exit the file) Hope this helps:).
