把Redhat Linux5.0 的cd iso合并成dvd的脚本

liukun2009

最近找Redhat Linux5.0 x86_64的DVD ISO文件，结果一直找不到，却找到了6个cd的ISO，因为最后一个为源码盘，暂时不管，把其他5个CD合并成一个DVD，脚步如下：
vim dvd.sh
#!/bin/bash
# by Chris Kloiber
# A quick hack that will create a bootable dvd iso of a Red Hat Linux
# Distribution. Feed it either a directory containing the downloaded
# iso files of a distribution, or point it at a directory containing
# the "RedHat", "isolinux", and "images" directories.
# This version only works with "isolinux" based Red Hat Linux versions.
# Lots of disk space required to work, 3X the distribution size at least.
# GPL version 2 applies. No warranties, yadda, yadda. Have fun.
if [ $# -lt 2 ]; then
echo "Usage: `basename $0` source /destination/DVD.iso"
echo ""
echo " The 'source' can be either a directory containing a single"
echo " set of isos, or an exploded tree like an ftp site."
exit 1
fi
cleanup() {
[ ${LOOP:=/tmp/loop} = "/" ] && echo "LOOP mount point = \/, dying!" && exit
[ -d $LOOP ] && rm -rf $LOOP
[ ${DVD:=~/mkrhdvd} = "/" ] && echo "dvd data location is \/, dying!" && exit
[ -d $DVD ] && rm -rf $DVD
}
cleanup
mkdir -p $LOOP
mkdir -p $DVD
if [ !`ls $1/*.iso 2>&1>/dev/null ; echo $?` ]; then
echo "Found ISO CD images..."
CDS=`expr 0`
DISKS="1"
for f in `ls $1/*.iso`; do
mount -o loop $f $LOOP
cp -av $LOOP/* $DVD
if [ -f $LOOP/.discinfo ]; then
cp -av $LOOP/.discinfo $DVD
CDS=`expr $CDS 1`
if [ $CDS != 1 ] ; then
DISKS=`echo ${DISKS},${CDS}`
fi
fi
umount $LOOP
done
if [ -e $DVD/.discinfo ]; then
awk '{ if ( NR == 4 ) { print disks } else { print ; } }' disks="$DISKS" $DVD/.discinfo > $DVD/.discinfo.new
mv $DVD/.discinfo.new $DVD/.discinfo
fi
else
echo "Found FTP-like tree..."
cp -av $1/* $DVD
[ -e $1/.discinfo ] && cp -av $1/.discinfo $DVD
fi
rm -rf $DVD/isolinux/boot.cat
find $DVD -name TRANS.TBL | xargs rm -f
cd $DVD
mkisofs -J -R -v -T -o $2 -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table .
/usr/lib/anaconda-runtime/implantisomd5 --force $2
cleanup
echo ""
echo "Process Complete!"
echo ""


把5个iso放到/u01下
执行一下命令
./dvd.sh /u01 /u01/redhat5.0_x86_64_dvd.iso
结果如下：

在linux下进行挂载ISO
mount -o loop -t iso9660 redhat5.0_x86_64_dvd.iso /media
