Create ISO in Linux

Linux production ISO-General Linux technology-Linux technology and application information, the following is a detailed description. Usage: mkisofs-a-I-J-r-o filename. iso/Directory

Purpose: Create an iso image for all files in a directory in Linux. in addition, I have added parameters to ensure that the disc you created can also be used in windows (iso has file size restrictions...)

In Linux, we can copy the content on the optical drive to an ISO file by using the copy command, such as cp/dev/cdrom xxx. iso.

In a Windows system, a special software such as WINISO must be required for ISO production. I didn't expect Linux to be so simple. Linux is really a good thing.

In Linux, you can also use the dd command to make ISO: dd if =/dev/cdrom of =/root/rh9-1.iso bs = 512

What is an ISO file?

ISO file: a file with the iso extension. it is an ISO file format, a file system format on a CD. Simply put, the data is organized on the data disk:

It features:

1) a maximum of 8 sub-directories can be included (you can use RockRidgeExtension to increase this limit)

2) the maximum file name is 32 characters.

3) the file size cannot exceed 650 MB.

2. how to use ISO files in Linux

Generally, the Kernel of Linux supports the file format of the iso9660 file. if not, you need to recompile the Kernel to add support for it. You only need to use the following command to read its content from the/path directory:

Mount-t iso9660-o loop xxx. iso/path

In Linux, we can copy the content on the optical drive to an ISO file by using the copy command, such as cp/dev/cdrom xxx. iso.
