The command line may be ancient and mostly supplanted by GUIs, but there are times when it really is the easiest and fastest way to get some things done. (Some of those examples take advantage of the above-described skip feature.) You can do a lot more with curly braces this guide provides many more examples. This how-to explains the steps involved in installing and switching to a newer version of bash. To make this work, though, you must be on a newer bash shell than ships with macOS. 2 bit tells the expansion to only output every second letter. 'Users/foo/bar' is the actual location of. 'newfolder' is the name of the virtual folder that will be created in the root of the file system. You need to create the file /etc/nf, which should be owned by root and group wheel with permissions 0644. This is an easy way to the path to copy into Terminal without. Type cd into Terminal and drag the folder or file (s) you want to change permissions on by dragging it into Terminal window. In this example, we change directory to /opt/X11.
#CREATE NEW FOLDER IN MAC TERMINAL HOW TO#
Here they're being used to generate sequences-you can use numbers or letters, and as long as they're separated by two dots, the shell will attempt to fill in the missing values-you can even reverse the order. This allows you to create what appears to be folders at the root of the file system. In this video youll learn how to easily create a new directory on your computer right from the terminal command line. Let’s get into the directory of files we want to change permissions to. In the shell (both bash in pre-Catalina, and zsh in Catalina), the curly braces have a number of uses. Note: Before you play around with this, I suggest creating a test folder on your Desktop (or wherever), and then, in Terminal, execute cd ~/Desktop/testfolder before you do anything else-that way, the folder structures will be within one folder, and easily deleted if something doesn't go quite right. You can make changes to your files right.
nanoBut in Terminal, you can create the entire structure with just one command:
(Hopefully obviously, the same structure repeats within each separate year's folder.) Creating that many multi-leveled folders in Finder would be time consuming and tedious. One way to handle that would be with a folder structure like this: Let's say you need a folder structure to handle reports that you'll be receiving weekly, but need to keep track of over both quarters and years. But a quick trip to Terminal makes the task very fast, and it's not overly complicated. Have you ever needed to create an empty folder structure with many levels of repetitively-named folders? This doesn't happen a lot, obviously, but if you try using Finder for this task, you'll quickly discover it's really tedious.
