本文介绍了如何利用`file -s`命令在Linux中检查不同磁盘分区的文件系统类型，包括DOS/MBR引导扇区、SGI XFS、LVM2 PV、ext4等。此外，还提到了`parted`、`gdisk`等相关工具的使用。

用file -s查看各磁盘文件系统及简述装置

Specifying the -s option causes file to also read argument files which are block or character special files. This is useful for determining the filesystem types of the data in raw disk partitions, which are block special files.

相关：Hex code or GUID

parted /dev/sda print裡的name。

gdisk /dev/sda、p裡的code及name (按q不存退出)

file -s /dev/sda：DOS/MBR boot sector (disk安装原始开机碟)

file -s /dev/sda1：data (part。partition)

file -s /dev/sda2：SGI XFS filesystem data (blksz 4096, inosz 512, v2 dirs) (boot安装分割开机)

file -s /dev/sda3：LVM2 PV (Linux Logical Volume Manager), UUID: H0rYO0-EdqD-exar-ySOj-BCdU-tlg9-DqTtzw, size: 32216449024 (part。partition，含安装根目录、安装分割/swap/、安装/home)

file -s /dev/sda4：SGI XFS filesystem data (blksz 4096, inosz 512, v2 dirs) (用gdisk分割的xfs)

file -s /dev/sda5：Linux rev 1.0 ext4 filesystem data, UUID=c85833c8-a9ac-4635-beb6-21050b084b8f, volume name "vbird_ext4" (needs journal recovery) (extents) (64bit) (large files) (huge files) (用gdisk分割的ext4)

file -s /dev/sda6：DOS/MBR boot sector (用档案仿真的磁盘)

file -s /dev/sda7：/dev/sda7: DOS/MBR boot sector, code offset 0x58+2, OEM-ID "mkfs.fat", sectors/cluster 8, Media descriptor 0xf8, sectors/track 63, heads 255, hidden sectors 70219776, sectors 1069056 (volumes > 32 MB), FAT (32 bit), sectors/FAT 1048, reserved 0x1, serial number 0x9483cc00, unlabeled (用parted分割的vfat)

file -s /dev/loop0：SGI XFS filesystem data (blksz 4096, inosz 512, v2 dirs) (用dd档案仿真成磁盘)

file -s /dev/sr0：DOS/MBR boot sector; partition 2 : ID=0xef, start-CHS (0x3ff,254,63), end-CHS (0x3ff,254,63), startsector 23128, 19888 sectors (光盘挂载开机*.iso映象檔)
