xmount:tldr:eb192
The command xmount is being used in this snippet. xmount is a command-line tool that allows one to mount disk images in various formats. Let's break down the provided command:
--in ${raw}: This specifies the input disk image format as a raw image. ${raw} is likely a variable referring to a raw image file.
${path-to-image-dd}: This variable likely holds the path to a disk image file in the DD format.
--out ${dmg}: This specifies the output disk image format as a DMG image. ${dmg} is probably a variable referring to the desired output file name.
${mountpoint}: This variable holds the path to the directory where the disk image will be mounted.
Overall, the command is using xmount to convert a raw disk image file (${raw}) and a DD disk image file (${path-to-image-dd}) to a DMG disk image file (${dmg}). The resulting DMG image will be mounted at ${mountpoint}.
