![]() ![]() Using /opt is thus no less safe than using /usr/local, and it's generally preferred over using a combination like /usr/local/opt that doesn't get the distinction. They have slightly different purposes, but the difference is subtle (the full description is answered here if you're interested). You can use sudo chown -R /opt/foldername username (where username is your username, if you don't know your username you can type whoami on the command line to find out) to claim ownership of the folder and everything that it contains if you lack write access.Ä®dit: because there was some confusion I'm pointing out here that /opt is as much a standard in UNIX-derived systems as /usr/local. The first form will access a folder off the root, the second will access a folder within your home folder.Äepending on how it was set up it may or may not have provided you with write access. There aren't any currently, so there is nothing displayed in the Terminal.Based on your description, use /opt/foldername on the command line instead of ~/opt/foldername. For example, you could type "ls Downloads/Examples/Example1/Test" to list the files inside the "Test" folder. This is infinitely extensible, meaning that you can dig as deep as you want by utilizing the "/". Looking at the Finder window shows you that they are the same thing. For example "ls Downloads/Examples" will list the contents of the "Examples" folder that is inside the "Downloads folder" I can even dig deeper by using the "/" and typing a folder inside the Downloads directory. You can redirect the resulting list to a textfile by adding > textfilename to the last command. Find the files with a name starting with a 'dot'. Enter this command: cd .Make hidden files and folders visible easily by using a shortcut or. So the only other possible answer your question is 'use the Terminal'. Just to continue to help you visualize this, I'll open the Downloads folder in Finder. Open a Terminal, iTerm, Hyper, or Kitty window at your current local path. This time, when I press Enter, we see the contents of the Downloads folder. ls -A The only difference here is that you won't see the. In this case, the command is "ls Downloads". You can display hidden files along with other files using the -a option of the ls command: ls -a There is another way to show hidden files with the ls command. To do this, we simply type the "ls" command, followed by the directory whose contents we want to list. ![]() Let's view the files and folders inside the "Downloads" directory, while staying in our current directory. Returning to our showing hidden files option, this too was accomplished by way of using the defaults directive with this syntax: defaults write. ![]() One will keep us in the current working directory, while the second will actually move us into the other directory before we list the files. Now, let's say we want to see the files and directories inside one of the directories listed here. So, when I type "ls" and press "Enter" we see the same folders that we do in the Finder window. To see them in the terminal, you use the "ls" command, which is used to list files and directories. In the Finder window, we see the contents of the "/Users/ModulesUnraveled" directory. Listing files and folders in the current directory This will make it easier to follow along throughout the series. So, when I type ls and press Enter we see the same. I'll also split the screen so that the terminal is on the left and the Finder window is on the right. To see them in the terminal, you use the ls command, which is used to list files and directories. Let's go to this directory in Finder to follow along. If I type it and press Enter, the result is "/Users/ModulesUnraveled". ![]() There may come a time when you don't know which directory you are currenly in. Windows will commonly use ">".) Seeing which directory you're currently in (Some systems use a symbol other than the "$" including "%" or "#". Finally we'll see "ModulesUnraveled" which is my user name, and a "$" which is the prompt that indicates it is ready for me to type my command. hidden file and display the file names of those that exist. If you are writing a script, then these lines will read the. You'll see "Brians-MacBook-Air" which is my computer name, followed by a colon and then a "~" (which indicates the user home directory) and that is the directory I am currently in. However, this and all of the other answers miss files that are in the current directory's. Once it's opened you'll see the last login time on the first line, while the second line shows information about my computer, what folder I'm in and who I'm logged in as. The first thing we need to do is open up our terminal. In this video we'll use the "pwd" command to see what directory we are in, and the "ls" command to list the files that are in our current directory. ![]()
