准备刻一张FreeBSD-7.0-RELEASE的DVD,网上很多介绍都是在Windows下使用什么iso提取工具的,貌似很麻烦。参考了一些FreeBSD高手的实现,我写了一个简单的脚本,主要功能是从3张disc*.iso创建出一个dvd.iso
1,准备工作:
工作目录 work/ 和 3张disc*.iso, 比如
work/7.0-RELEASE-i386-disc1.iso
work/7.0-RELEASE-i386-disc2.iso
work/7.0-RELEASE-i386-disc3.iso
2,用以下代码创建脚本文件,比如 mkdvd.sh,放在work目录下。用root用户执行,将在work目录下产生一个7.0-RELEASE-i386-dvd.iso的文件。
#!/bin/sh disc1=`ls | grep "disc1.iso"` disc2=`ls | grep "disc2.iso"` disc3=`ls | grep "disc3.iso"` dvd=`echo $disc1 | sed "s/disc1/dvd/"` ## Prepare temporary dir to store dvd files if test -e tmp && test -d tmp then rm -fr tmp fi mkdir tmp ## Extract contents of each disc*.iso to temporary dir for disc in $disc3 $disc2 $disc1 do mdconfig -a -f $disc -u 66 if test -e /dev/md66 then echo Extract $disc ... mount -t cd9660 /dev/md66 /mnt tar -cf - -C /mnt . | tar -xf - -C tmp/ umount /mnt mdconfig -d -u 66 else echo Can not create memory disk. exit -1 fi done ## Merge index to point to the first disc echo Merge index ... cd tmp cat INDEX | sed "s/||2/||1/g" > index cat index | sed "s/||3/||1/g" > INDEX cat INDEX | sed "s/|3/|1/g" > index mv index INDEX cd .. ## Make dvd iso file echo Make $dvd ... mkisofs -R -no-emul-boot -b boot/cdboot -o $dvd tmp rm -fr tmp exit 0 |
