1.diskutil list查看硬盘分区;

xiaqiangdeMacBook-Pro:~ xiaqiang$ diskutil list/dev/disk0 (internal, physical):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      GUID_partition_scheme                        *121.3 GB   disk0   1:                        EFI EFI                     209.7 MB   disk0s1   2:          Apple_CoreStorage Macintosh HD            60.4 GB    disk0s2   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3   4:         Microsoft Reserved                         16.8 MB    disk0s4   5:                  Apple_HFS BOOTCAMP                60.0 GB    disk0s5/dev/disk1 (internal, virtual):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                  Apple_HFS Macintosh HD           +60.0 GB    disk1                                 Logical Volume on disk0s2                                 3802161B-56DA-42B2-BAC3-4269F1E91DF6                                 Unencrypted

2.diskutil eraseVolume JHFS+ BOOT disk0s5 格式化磁盘分区,BOOT是卷的名称,这个随便命名,disk0s5是你要删除的分区的编号;

xiaqiangdeMacBook-Pro:~ xiaqiang$ diskutil eraseVolume JHFS+ BOOT disk0s5Started erase on disk0s5 BOOTCAMPUnmounting diskErasingInitialized /dev/rdisk0s5 as a 56 GB case-insensitive HFS Plus volume with a 8192k journalMounting diskFinished erase on disk0s5 BOOT

3.diskutil mergePartitions HFS+ Macintosh HD disk1 disk0s5 合并两个分区,后面disk0s5这个是你要删除的分区,前面那个是要把删除分区合并到的分区;

//合并分区的命令是正确的,在这里这个结果是提示这个磁盘没有提供改变大小的功能;eg:如果disk1原来的大小为40GB,disk0s5原来大小为620MB,那执行完这条命令语句后就是删除了disk0s5的分区,将disk0s5的大小合并到disk1分区上面,此时合并后disk1的大小就为40.5GB;xiaqiangdeMacBook-Pro:~ xiaqiang$ diskutil mergePartitions JHFS+ Macintosh disk0s2 disk0s5The chosen disk does not support resizing.Do you wish to format instead? (y/N) yMerging partitions into a new partition     Start partition: disk0s2     Finish partition: disk0s5 BOOTMerging partitions encountered error "Invalid request (-69886)".The erase will not occur.
