有没有办法从命令行更改.iso文件卷ID？

8

我.iso在linux下有一个文件，一直在尝试寻找一种无需重新创建.iso文件即可更改卷ID的方法。例如，大多数创作工具都mkisofs提供了用于设置音量的开关(-V)。但是我不知道如何更改现有.iso文件。

为了澄清起见，我要更改的位是此Volume id:字符串。这是isoinfo命令中的转储示例。

% isoinfo -d -i /usr/share/virtualbox/VBoxGuestAdditions.iso

卷ID始终以32字节ASCII字符串存储在偏移量0x8028处。在适当位置进行编辑。

#!/usr/bin/perl
use strict;
use warnings;

die "Use: $0 <iso_file> <new volume id>\n" unless @ARGV == 2;
open my $file, "+<", $ARGV[0] or die "Cannot open: $!";
seek $file, 0x8028,0;
printf $file "%-32.32s", uc($ARGV[1]);

测试-（isovolid.pl是上述脚本的名称）：

$ genisoimage -V A123456798012345678901234567890X -o aaa.iso *
$ isoinfo -d -i aaa.iso | grep 'Volume id:'
Volume id: A123456798012345678901234567890X
$ ./isovolid.pl aaa.iso NEWVOLUMEID
$ isoinfo -d -i aaa.iso | grep 'Volume id:'
Volume id: NEWVOLUMEID

我想补充一点，以防ISO额外包含Joliet文件系统，可以从该文件系统中使用卷ID。就我而言，它存储在UTF-16中的偏移量0x8828处。我还添加了以下两行来更改该ID：seek $ file，0x8828,0; binmode（$ file，“：encoding（utf-16be）”）; printf $ file“％-16.16s”，uc（$ ARGV [1]）;

xorriso可以这样做：
