If, for one reason or another, you need to look for the disk ID or disk node ID (such as / dev / disk0s2) of a disk attached to your Mac, perhaps the easiest way to get this information from the command line is with the diskutil utility.
The location of the disk ID node in Mac OS
To get started, open the extension in the / Applications / Utilities / directory, and then type the following syntax script:
diskutil list
This command lists all installed volumes and their corresponding partitions, as we have discussed earlier, but for this purpose we use it specifically to find the disk ID or IDENTIFIER. So find the name of the disc in question, and then look for the disc ID in the ID ID section. It is displayed on the right side of the terminal:
Because the command prints all volumes and their disk tags, it can provide unnecessary information. If you don’t want to go through the list, or if you know the disk name of the drive for which you want to find the disk ID, you can use the diskutil command conversion to get the details right away like this:
discussion info “Macintosh HD” | grep Node
This may return one of the following: $ diskutil info “Macintosh HD” | grep NodeDevice Node: / dev / disk1
Where “/ dev / disk1” is that node identifier.
You can also expand it a bit, which can be useful in determining the volume you’re looking for:
$ diskutil info “Macintosh HD” | grep DeviceDevice Identifier: disk1Device Node: / dev / disk1Device / Media Name: Macintosh HDDevice Block Size: 512 BytesDevice Location: Internal
This indicates the location of the device, which means an internal or external drive, which can help lower the volume when many disks or storage utilities are connected to your Mac.
The Diskutil command is very powerful and has many uses for the Mac user who doesn’t care about navigating the command line. Yes, it’s a bit advanced, but because of its potential and power, it’s sometimes the only way to get certain types of data quickly in MacOS and Mac OS X.
