"CentOS" Disk Management with VIM compiler

One, view hard disk or directory capacity

1.DF [-hmkit]

-H View System disk usage

-M using MBytes to display results

-K displaying results using Kbytes

-I view Inode

-T view type

2.du [-abhkms] [directory name]

-S only lists the total value of the last calculation

-K display in kilobytes (default)

-m Display in MB

-h display in appropriate units

-B Display in units

-a lists all files and directories, the default value is the value of the list directory

Note: Only one file is allowed in a block, the default file size for a block is 4K

Ii. partitioning and formatting of disks

Disk Trilogy: Partitioning--formatting--mount

1.fdisk [-l][device name]

-l lists the partition table of the hard disk device directly

Eg:fdisk-l/dev/sdb

"Specific steps to be added later"

2.MKE2FS [-B block-size][-i inode-size][-l] [partition]

-L Sets the label (header name) for this sector

Eg:mke2fs-t ext4-b 1024/DEV/SDB1

3.mount [-ahlo][partition name, can also be used uuid][mount point]

-O to be supplemented (bird brother P134)

-A according to the contents of/etc/fstab in all relevant hard disk------(/etc/fstab for automatic boot loading)

Umount [-l][partition] Unload mount

-L is expressed as mandatory

worth knowing usage: Mount--bind/home//mnt/

The/home/is attached to the/mnt/below, equivalent to the establishment of a soft link, delete/home/this "soft link" will expire

Third, VIM editor

When opening a file, vi +10 filename, move the cursor to line tenth of the file

Look at the line number, with Set Nu; cancel this, use set Nonu

1. General mode

Common shortcut keys:

Copy: "yy", "10yy"

Paste: "P", "5p"

Delete/Cut forward: "X", "10x"

Delete/cut back: "X", "10X"

Delete one line: "DD", "10DD"

Optional: "V"

The cursor jumps to the beginning of the first character: "^"

Cursor jumps to the beginning: "0"

Cursor jumps to the end: "$"

2. Edit mode

I,o,a,i,o,a

3. Command mode

Search down:/name

Search up:? name

Find Replacement: ": 1. $s/iptable/iptable/g" or "%s/iptable/iptable/g"

G represents the global meaning, and the code's role is to replace all iptable in the range with Iptalbe

Remove the highlighted yellow background: Nohl (NO)

If VIM is not already installed, you can use the command Yum install-y vin-enhanced installation
