In general, when I need to list hidden files, this is the command I use. Now we see the long format of all files in this directory, including hidden files. You could enter each option separately like this "ls -a -l Downloads", but you can actually combine options, which means you can simply type "ls -al Downloads", so that's what I'll do. Now, I mentioned that I use these commands together, so I'll show you how to do that. The "-l" option shows the list in "long format" which includes the permissions, number of hard links, owner, group, size, last-modified date and the filename. It's the "-l" option, and if I type "ls -l Downloads" you can see it in action. To display all hidden files and directories we can use -a option. thus not showing hidden files or directories. By default ls ignores all entries starting with. When doing a ‘ls -’ you can see that the files I changed with ‘chflags’ to hidden have a com.apple. After doing some research I found out that is for signifying Extended Attributes. When using ‘ls -la’ the hidden files and folders show a symbol next to it. There are other options that can be passed to the "ls" command, and if you're interested, I'd encourage you to Google them, or take a look at this Wikipedia article but I'm just going to show you one more, because I almost never use the -a option without it. In Linux, all hidden files and directories start with. I have some files I hid using ‘chflags hidden MyHiddenFolder’. (Windows machines also have a similar file.) The ".hiddenfile" file is actually just a dummy file that I created. The ".DS_Store" file is a metadata file that the Mac operating system creates in each directory and contains information about that directory and its contents. As you can see, there are several files that start with a dot. This tells the ls command to list 'all' files and folders including hidden ones, i.e. To show hidden files you must use the -a option. You'll also notice that they are not shown in Finder by default. Windows systems do not support FIFO files or sockets (as files) and consider all files that are not directories or symbolic links to be executable files. However, ls doesn't list hidden files by default. These are hidden files, and are not included in the "ls" command by default. We also see a few files that start with a ".". Use the Get-ChildItem (or its alias ls) command in PowerShell to get a list of hidden files from directories. I'll talk more about that in the next section. To show all hidden files inside a specific directory: Open your Mac Terminal. However, sometimes you need to see and access them. The "." and "." items simply represent the current directory and one level up respectively. By default, some files are hidden on Mac computers. This time, we see a few more items in the list. For example, the "-a" option will show all files and folders, including hidden ones. The "ls" command has many options that, when passed, affect the output.
