在Mac OS X系统下 用dd命令将iso镜像写入u盘

时间:2024-03-01 11:19:58

一、 Mac下将ISO写入U盘可使用命令行工具dd,操作如下:

1、找出U盘挂载的路径,使用如下命令:diskutil list
2、将U盘unmount(将N替换为挂载路径):diskutil unmountDisk /dev/disk[N]
3、写入U盘:sudo dd if=iso路径 of=/dev/rdisk[N] bs=1m  rdisk 中加入r可以让写入速度加快

二、具体操作示例:


1. 将iso转换成dmg 转iso 用

UDRW 替换为 UDTO
 1 lapommedeMacBook-Pro:~ lapomme$ sudo hdiutil convert -format UDRW -o /linux.dmg kali.iso
 2 Password:
 3 正在读取Master Boot Record(MBR:0)…
 4 正在读取Kali Live (Apple_ISO:1)…
 5 正在读取(Windows_NTFS_Hidden:2)…
 6 ............................................................................
 7 正在读取(DOS_FAT_12:3)…
 8 ..............................................................................
 9 已耗时:10.178s
10 速度:288.3M 字节/11 节省:0.0%
12 created: /linux.dmg

 

2. 查看u盘盘符

 1 lapommedeMacBook-Pro:~ lapomme$ diskutil list
 2 /dev/disk0 (internal, physical):
 3 #: TYPE NAME SIZE IDENTIFIER
 4 0: GUID_partition_scheme *251.0 GB disk0
 5 1: EFI EFI 209.7 MB disk0s1
 6 2: Apple_CoreStorage Macintosh HD 250.1 GB disk0s2
 7 3: Apple_Boot Recovery HD 650.0 MB disk0s3
 8 /dev/disk1 (internal, virtual):
 9 #: TYPE NAME SIZE IDENTIFIER
10 0: Apple_HFS Macintosh HD +249.8 GB disk1
11 Logical Volume on disk0s2
12 E2BD4617-5A22-46A9-A6F4-D54E3EE92BBC
13 Unencrypted
14 /dev/disk2 (external, physical):
15 #: TYPE NAME SIZE IDENTIFIER
16 0: FDisk_partition_scheme *62.0 GB disk2
17 1: DOS_FAT_32 UNTITLED 1 62.0 GB disk2s1
18 /dev/disk3 (disk image):
19 #: TYPE NAME SIZE IDENTIFIER
20 0: FDisk_partition_scheme +3.1 GB disk3
21 1: 0x17 3.0 GB disk3s1
22 2: DOS_FAT_12 NO NAME 110.1 MB disk3s2

 

3. 取消挂载U盘

1 lapommedeMacBook-Pro:~ lapomme$ diskutil umountDisk /dev/disk2
2 Unmount of all volumes on disk2 was successful

 

4. 用dd命令写入U盘

说明:

(1)sudo dd if=源路径 of=/dev/r卷标 bs=1m [‘r’ 会让命令执行加快一点] [‘bs’为一次填充的容量]

(2)获取映像名称和完整路径可以直接将文件拖入终端,即在终端中显示

1 lapommedeMacBook-Pro:~ lapomme$ sudo dd if=/linux.dmg of=/dev/rdisk2 bs=1m
2 2934+1 records in
3 2934+1 records out
4 3076767744 bytes transferred in 149.567568 secs (20571089 bytes/sec)

 

5. 查看磁盘进度,可以用iostat命令查看磁盘写入状态

1 lapommedeMacBook-Pro:~ lapomme$ iostat -w 2
2 disk0 disk2 disk3 cpu load average
3 KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us sy id 1m 5m 15m
4 102.71 25 2.49 598.70 0 0.15 24.76 1 0.02 5 4 90 2.04 1.71 1.69
5 512.00 48 23.93 1024.00 24 23.93 0.00 0 0.00 1 3 96 2.11 1.74 1.69
6 473.00 26 11.99 1024.00 12 11.98 0.00 0 0.00 3 3 93 2.11 1.74 1.69
7 491.68 50 23.99 1024.00 24 23.99 0.00 0 0.00 24 8 68 2.11 1.74 1.69

 

6. 操作完毕后将U盘弹出

1 lapommedeMacBook-Pro:~ lapomme$ diskutil eject /dev/disk2
2 Disk /dev/disk2 ejected
