Get Octal File Permissions in Command Line on Mac OS

Check tutorial of How to Get Octal File Permissions from Command Line in Mac OS

So after a lot of requests from our users here is a guide about How to Get Octal File Permissions from Command Line in Mac OS.

Command line users are probably familiar with using chmod to set file permissions in numeric or octal format, for example running a command like ‘chmod 755 filename’, but have you ever wondered how to get file permissions in octal format?

If you want to see or view the octal numeric value of permissions of a file or folder from the command line, you can go to the stat command in Mac OS.

We assume you have a reasonable level of command line experience and comfort, if you don’t then this article is probably not relevant to you. Most Mac users will only view or change file permissions through the Mac Finder as described elsewhere (if so), while this particular article is aimed at more advanced users.

How to Get numeric chmod permission values ​​on Mac

To get started, launch the Terminal app from / Applications / on the Mac and use the following commands:

stat -f% A file.txt

For example, that command could run something like the following:

$ stat -f% A wget-1.18.tar.gz644

Where, in this example, ‘644’ is the octal value of those file permissions.

Alternatively, you can use -f and% OLp (yes that’s an uppercase ‘o’ and not a zero), the output is the same assuming the file is also:

stat -f% OLp / Applications / System Preferences.app

Sample output for that command might look like this, showing numeric octal permissions for the target item:

$ stat -f “% OLp” ‘/ Applications / System Preferences.app’775

In this example, the “System Preferences” application has an octal permission value of 775.

How to    get file permissions as octal value on Mac from command line

You don’t need to use quotes, but if for some reason you want to escape a filename or path, or for scripting purposes, they are easy to put:

stat -f “% OLp” ‘/ Applications / System Preferences.app’

The -f flag is for format, you can read more about specific formatting options for the stat output from the manual page about stat with ‘man stat’.

In the last case of a command, the “O” (capital letter o) is specific to achieving octal output.

Knowing the exact numeric permissions of a file or folder is immensely useful for so many reasons, and it can be useful to know if you are adjusting the permissions of different items, or even if you are moving files on the Mac and want to keep exact consents and verify them afterwards. There are tons of other uses too, especially if you’re running a server of any kind from the Mac.

These commands should work the same for getting octal permissions in almost any version of macOS, macOS, or Mac OS X, regardless of how the naming convention is capitalized. It’s worth noting, however, that the approach to obtaining octal permissions on the Mac is different from the rest of the Linux world, so if you’re coming to the Mac from the Linux world, you’ll need to tweak the stat command flags to accurately to get the permissions in octal format, we’ll get to that quickly below.

Obtain Octal file permissions from the command line in Linux

To be thorough, we’ll briefly discuss getting octal permissions in the Linux world too, where you can use the following to get the octal file permissions:

stat -c “% a% n” / Path / To / File

You can also use the stat -c command more simply:

stat -c% a /Path/To/File.txt

Either way, the output of the numeric value will be the same as long as the input target file is of course the same.

Again, these last two approaches are Linux specific, and you will have to use the methods described above to get octal values ​​of permissions from a file in Mac OS.
