Example 1: Set Read, Write and Execute For User, Groups and Others Here are a few examples of adding and removing permissions from my folder. The folder I created earlier called My Folder has the permissions drwxr-xr-x which means: add permissions, delete permissions, clear permissions, or use the defaults), and the permissions themselves (read, write, or execute). To change the file permissions on a file, you need to specify the category (User, Group, Others, or all three), the type of operation (e.g. This mode is only recommended for advanced users, but if you’re using chmod regularly you’ll get to know the different codes and might find it more convenient.įor the moment we’ll focus on the symbolic mode which is rather more human-readable. The absolute mode uses an octal number with various values that can be combined to set many of the different read, write and execute permissions at once. The chmod command runs in two modes – absolute and symbolic mode. It has hundreds of different options (type man chmod in Terminal to view it’s help files), but we’ll concentrate on the simplest ones in this tutorial. The chmod command is the easiest way to do this. The next step is to actually change the file permissions to whatever you want.

The first item “d” in these permissions indicates it’s a directory rather than a file (but the same principles apply). You’ll notice that the item My Folder (the last item in the list) has the permissions drwxr-xr-x.

In the leftmost column, the file permissions for each item are listed. List the properties of files in the current directory In this case I’ve actually used the -al option to also display the “.” (current) and “.” (upper level) folders, but it’s not necessary. You should see the list of files in the current directory along with all the relevant file permissions for each item in the directory, as shown below. Inspect the current file permissions by typing in the ls command with the -l option to show in the long format, for example: Note that you will need to use quotes around filenames only if the item you want to edit contains a space, as it does in this case.ģ.

Open Terminal (type Terminal into Spotlight or open from the Applications -> Utilities folder). In this example we’ll use a temporary folder called My Folder on which to demonstrate the various file permissions options.ġ.
