1、用dd命令
#dd if=/dev/cdrom of=/***/目的文件.iso
上面的命令是在將光盤作成iso文件
2、用mkisofs 命令
#mkisofs -r -J -V 卷標名 -o 目的文件.iso 源文件
上面的命令是將 “源文件” 文件及目錄作成 “目的文件.iso”。
例子 ：
# mkisofs -r -J -V widebright -o widebright.iso /widebright
在Linux系統上建了一個iso文件，然後放到Windows xp上，結果winrar能夠正確解壓，使用DAEMON Tools 作為虛擬光盤加載之後，也很正常。
NAME
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.
主要是為了兼容Windows系統。
卷標名——指所做成iso文件後插入虛擬光盤時所顯示的名字。
-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.
更多的選項可以用 man mkisofs 查看。
