Script to create a disk image from a folder on macOS devices

A disk image is a file that holds a replica of the data on a disk volume or storage device. As an administrator, you may need to create a disk image from a folder to be able to mount it on other devices/servers conveniently. Disk image provides you with extended control over the availability and accessibility of this folder and its contents. For instance, you can put up one disk image on multiple machines and quickly set up several computers in one go instead of setting them up separately. By creating a disk image of a computer drive, you can also store the data from a computer without keeping the actual hardware around. Additionally, disk images can help you transfer large files or programs over the web. With Hexnode’s Execute Custom Script action, you can remotely create a disk image from a folder on your macOS devices using this bash script.
