Parted command

• Although we can use fdisk Command to partition the hard disk quickly , But for higher than 2TB Hard disk partition , This command is powerless , You need to use parted command

• parted Commands can be partitioned and formatted directly on the command line , however parted Interactive mode is the more common command mode , The way to enter the interactive mode is as follows ：

  [[email protected] ~]# parted  Hard disk device file name 
  # Then it will enter interactive mode 
  
   for example ：
  [[email protected] ~]# parted /dev/sda
  [[email protected] ~]# parted /dev/sda
  GNU Parted 3.1
   Use  /dev/sda
  Welcome to GNU Parted! Type 'help' to view a list of commands.
  (parted)    # Entered interactive mode , You need to enter an interactive command 
  
   Common steps of creating partition mount ：
  [[email protected] ~]# lsblk
  NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
  sda      8:0    0 893.8G  0 disk 
  ├─sda1   8:1    0   512M  0 part /boot
  ├─sda2   8:2    0    65G  0 part /
  ├─sda3   8:3    0     8G  0 part [SWAP]
  ├─sda4   8:4    0     1K  0 part 
  └─sda5   8:5    0 820.3G  0 part /home
  sdb      8:16   0   1.8T  0 disk 
  
  [[email protected] ~]# echo -e "mklabel gpt\nmkpart primary 1 100%\nquit\n" | parted /dev/sdb
  # notes ：————————————————————————————————
   Before this command echo As input , That is, entering parted The command that interacts with the system after the command , There is a line break in the middle , As an interactive command input, it is like this 
  mklabel gpt   # Create a new disk volume label gpt
  mkpart primary 1 100%  # Create a partition , Capacity 100%, The default is create 1
  quit  # sign out
