导读： 分区之后，并不能直接使用，需要格式化成特定的文件系统。
格式化(format)是指对磁盘或磁盘中的分区（partition）进行初始化的一种操作，这种操作通常会导致现有的磁盘或分区中所有的文件被清除。

分区之后，并不能直接使用，需要格式化成特定的文件系统。 格式化(format)是指对磁盘或磁盘中的分区（partition）进行初始化的一种操作，这种操作通常会导致现有的磁盘或分区中所有的文件被清除。 1. mkfs 该命令用来在特定的分区创建linux文件系统，常见的文件系统有ext2,ext3,vfat等，执行mkfs命令其实是在调用:mkfs.ext3 | mkfs.reiserfs |mkfs.ext2| mkdosfs | mkfs.msdos | mkfs.vfat ...... NAME mkfs - build a Linux filesystem SYNOPSIS mkfs [options] [-t type] [fs-options] device [size] DESCRIPTION Thismkfsfrontendisdeprecatedinfavour of filesystem specific mkfs. utils. mkfs is used to build a Linux filesystem on a device,usuallyahard diskpartition.Thedevice argument is either the device name (e.g. /dev/hda1, /dev/sdb2),oraregularfilethatshallcontainthe filesystem.Thesize argument is the number of blocks to be used for the filesystem. In actuality, mkfs is simply a front-endforthevariousfilesystem builders(mkfs.fstype) available under Linux.The filesystem-specific builder is searched for via your PATH environment setting only.Please see the filesystem-specific builder manual pages for further details. baoli@ubuntu:~$ mkfs -h Usage: mkfs [options] [-t ] [fs-options] [] Make a Linux filesystem. Options: -t, --type=filesystem type; when unspecified, ext2 is used fs-optionsparameters for the real filesystem builder path to the device to be used number of blocks to be used on the device -V, --verboseexplain what is being done; specifying -V more than once will cause a dry-run -h, --helpdisplay this help -V, --versiondisplay version 将sda1分区格式化为ext4格式: mfks -t ext4 /dev/sda61 2. mke2fs 在磁盘分区上创建ext2、ext3、ext4文件系统，默认情况下会创建ext2。 mke2fs命令是专门用于管理ext系列文件系统的一个专门的工具。其还有像mkfs.ext2，mkfs.ext3，mkfs.ext4等衍生的命令linux分区工具，它们的用法mke2fs类似。 NAME mke2fs - create an ext2/ext3/ext4 filesystem SYNOPSIS mke2fs[ -c | -l filename ] [ -b block-size ] [ -C cluster-size ] [ -d root-directory ] [ -D ] [ -g blocks-per-group ] [ -G number-of-groups ] [-i bytes-per-inode ] [ -I inode-size ] [ -j ] [ -J journal-options ] [ -N number-of-inodes ] [ -n ] [ -m reserved-blocks-percentage ][-o creator-os ] [ -O [^]feature[,...]] [ -q ] [ -r fs-revision-level ] [ -E extended-options ] [ -v ] [ -F ] [ -Lvolume-label][-Mlast- mounted-directory ] [ -S ] [ -t fs-type ] [ -T usage-type ] [ -U UUID ] [ -V ] [ -e errors-behavior ] [ -z undo_file ] device [ fs-size ] mke2fs -O journal_dev [ -b block-size ] [ -L volume-label ] [ -n ] [ -q ] [ -v ] external-journal [ fs-size ] DESCRIPTION mke2fsis used to create an ext2, ext3, or ext4 filesystem, usually in a disk partition (or file) named by device. The file system size is specified by fs-size.If fs-size does not have asuffix,itis interpreted as power-of-two kilobytes, unless the -b blocksize option is specified, in which case fs-size is interpretedas thenumberofblocksize blocks.If the fs-size is suffixed by 'k', 'm', 'g', 't' (either upper-case or lower-case), then it is interpreted inpower-of-twokilobytes,megabytes, gigabytes, terabytes, etc.If fs-size is omitted, mke2fs will create the filesystembasedonthe device size. If mke2fs is run as mkfs.XXX (i.e., mkfs.ext2, mkfs.ext3, or mkfs.ext4) the option -t XXX is implied; so mkfs.ext3 will createafilesystem forusewithext3,mkfs.ext4 will create a file system for use with ext4, and so on. The defaults of the parameters for the newly created filesystem, if not overriddenbytheoptionslistedbelow,arecontrolledbythe /etc/mke2fs.conf configuration file.Seethemke2fs.conf(5)manual page for more details. 创建ext2fs： mke2fs /dev/sdb1 3. mkxxfs mkntfs, the same asmkfs.ntfs mkdosfs mkinitramfs mksquashfs mkisofs mkswap mklost+found mktemp 4. mkfs.xxx mkfs.cramfsmkfs.ext3mkfs.fatmkfs.msdosmkfs.vfat mkfs.bfsmkfs.ext2mkfs.ext4mkfs.minixmkfs.ntfs 4.1 mkfs.ext4 $ mkfs.ext4 -h mkfs.ext4: invalid option -- 'h' Usage: mkfs.ext4 [-c|-l filename] [-b block-size] [-C cluster-size] [-i bytes-per-inode] [-I inode-size] [-J journal-options] [-G flex-group-size] [-N number-of-inodes] [-d root-directory] [-m reserved-blocks-percentage] [-o creator-os] [-g blocks-per-group] [-L volume-label] [-M last-mounted-directory] [-O feature[,...]] [-r fs-revision] [-E extended-option[,...]] [-t fs-type] [-T usage-type ] [-U UUID] [-e errors_behavior][-z undo_file] [-jnqvDFSV] device [blocks-count] 4.2mkfs.vfatmkfs.fat 这个命令是格式化U盘的，vfat是文件系统类型，linux叫vfat, windows下叫FAT32 、 这样格完后，windows linux 默认都都能认识了。 vFAT与FAT向后兼容，但允许文件具有更长的名称， mkfs.vfat并且mkfs.fat是相同的工具。 NAME mkfs.fat - create an MS-DOS filesystem under Linux SYNOPSIS mkfs.fat [OPTIONS] DEVICE [BLOCK-COUNT] DESCRIPTION mkfs.fat is used to create an MS-DOS filesystem under Linux on a device (usually a disk partition).DEVICE is the specialfilecorresponding to the device (e.g. /dev/sdXX).BLOCK-COUNT is the number of blocks on the device.If omitted, mkfs.fat automatically determines the filesys‐ tem size. $ mkfs.vfat --help mkfs.fat 4.1 (2017-01-24) Usage: mkfs.fat [-a][-A][-c][-C][-v][-I][-l bad-block-file][-b backup-boot-sector] [-m boot-msg-file][-n volume-name][-i volume-id] [-s sectors-per-cluster][-S logical-sector-size][-f number-of-FATs] [-h hidden-sectors][-F fat-size][-r root-dir-entries][-R reserved-sectors] [-M FAT-media-byte][-D drive_number] [--invariant] [--help] /dev/name [blocks] （编辑：财气旺网 - 财气网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
