The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "how Linux establishes dmg files through the command line". Next, please follow the editor to study!

Linux system operation, many people do not know much about dmg files, let alone how to create dmg files, this article is to introduce Linux to use the command line to build dmg files, friends who do not understand can come to understand.

What is a DMG file and how do I open it?

DMG format is a mirror file on the MAC system, which can also be called a compressed file. If you use PC and do not have MAC OS X for X86 installed, don't bother. If you are using a Mac or have MAC OS X for X86 installed on PC, double-click the file on the MAC system to unlock it; if you want to burn the file to DVD, burn the file into a CD with toast: dmg= "disc image

Command line to create a dmg

Get the software version number automatically

APP_NAME= "Soulver"

VERSION=$ (/ usr/libexec/plistbuddy-c Print:CFBundleShortVersionString: "${APP_NAME} .app / Contents/Info.plist")

DMG_TMP= "${VOL_NAME}-temp.dmg"

DMG_FINAL= "${VOL_NAME} .dmg"

STAGING_DIR= ". / Install"

Create dmg

# Clean up folders

Rm-rf "${STAGING_DIR}"${DMG_TMP}"${DMG_FINAL}"

# Fault tolerant processing

If [$? -ne 0]; then

Echo "Error: Cannot compute size of staging dir"

Exit
