1、用dd命令 mkisofs - create an hybrid ISO9660/JOLIET/HFS filesystem with optional Rock Ridge attributes. SYNOPSIS mkisofs [ options ] [ -o filename ] pathspec [pathspec...] 注： -J Generate Joliet directory records in addition to regular iso9660 file names. 主要是为了兼容windows系统。 卷标名——指所做成iso文件后插入虚拟光盘时所显示的名字。 -R Generate SUSP and RR records using the Rock Ridge PRotocol to further describe the files on the iso9660 filesystem. -r This is like the -R option, but file ownership and modes are set to more useful values.The uid and gid are set to zero, because they are usually only useful on the author's system, and not useful to the client.All the file read bits are set true, so that files and directories are globally readable on the client.If any execute bit is set for a file, set all of the execute bits, so that executa bles are globally executable on the client. If any search bit is set for a directory, set all of the search bits, so that directories are globally searchable on the client.All write bits are cleared, because the CD-Rom will be mounted read- only in any case.If any of the special mode bits are set, clear them, because file locks are not useful on a read-only file system, and set-id bits are not desirable for uid 0 or gid 0. When used on Win32, the execute bit is set on all files. This is a result of the lack of file permissions on Win32 and the Cygwin POSIX emulation layer.See also -uid -gid, -dir-mode, -file-mode and -new-dir-mode.
