+# The `fdisk` command
+
+The `fdisk` command is used for controlling the disk partition table and making changes to it and this is a list of some of options provided by it : </b>
+- Organize space for new drives.
+- Modify old drives.
+- Create space for new partitions.
+- Move data to new partitions.
+  
+
+### Examples:
+
+1. To view basic details about all available partitions on the system:
+
+```
+fdisk -l
+```
+
+2. To show the size of the partition:
+
+```
+fdisk -s /dev/sda
+```
+
+3. To view the help message and all options of the command:
+```
+fdisk -h
+```
+
+### Syntax:
+
+```
+fdisk [options] device
+```
+
+### Some of the command options:
+
+On writing the following command 
+```
+fdisk /dev/sdb
+```
+the following window appears :
+![Options](https://media.geeksforgeeks.org/wp-content/uploads/20190219152451/Screenshot-711.png)
+and then you type m which will show you all options you need such as creating new partition and deleting a partition as in the following picture :

+# The `mount` command
+
+The `mount` command is used to mount 'attach' a filesystem and make it accessible by an existing directory structure tree.
+### Examples:
+
+1. Displays version information:
+
+```
+mount -V
+```
+
+2. Attaching filesystem found on device and of type type at the directory dir:
+
+```
+mount -t type device dir
+```
+
+### Syntax Forms:
+
+```
+mount [-lhV]
+```
+```
+mount -a [-fFnrsvw] [-t vfstype] [-O optlist]
+```
+```
+mount [-fnrsvw] [-t fstype] [-o options] device dir
+```

+### Additional Flags and their Functionalities:
+
+|**Short Flag**   |**Long Flag**   |**Description**   |
+|:---|:---|:---|
+|`-h`|<center>`--help`</center>|Dispaly a  help message and exists|
+|`-n`|<center>`--no-mtab`</center>|Mount without writing in /etc/mtab|
+|`-a`|<center>`--all`</center>|Mount all filesystems (of the given types) mentioned in fstab|
+|`-r`|`--read-only`|Mount the filesystem read-only|
+|`-w`|`--rw`|Mount the filesystem as read/write.|
+|`-M`|`--move`|Move a subtree to some other place.|
+|`-B`|`--bind`|Remount a subtree somewhere else *(so that its contents are available in both places)*.|

+# The `parted` command
+
+The `parted` command is used to manage hard disk partitions on Linux. It can be used to add, delete, shrink and extend disk partitions along with the file systems located on them.
+You will need root access to the system to run `parted` commands.
+
+**NOTE:** Parted writes the changes immediately to your disk, be careful when you are modifying the disk partitions.
+### Examples:
+
+1. Displays partition layout of all block devices:
+```
+sudo parted -l
+```
+
+2. Display partition table of a specific `disk`
+```
+sudo parted disk print
+```
+
+Examples of `disk` are /dev/sda, /dev/sdb
+
+3. Create a new disk label of `label-type` for a specific disk
+```
+sudo parted mklabel disk label-type
+```
+  
+`label-type` can take values "aix", "amiga", "bsd", "dvh", "gpt", "loop", "mac", "msdos", "pc98", or "sun" <br />
+
+4. Create a new partition in a specific `disk` of type `part-time`, file system is `fs-type` and of size `size` Mb.
+```
+sudo parted disk mkpart part-time fs-type 1 size
+```
+  
+`part-time` can take values "primary", "logical", "extended".<br />
+`fs-type` is optional. It can take values "btrfs", "ext2", "ext3", "ext4", "fat16", "fat32", "hfs", "hfs+", "linux-swap", "ntfs", "reiserfs", "udf", or "xfs"<br />
+`size` has to less than the total size of the specified disk. To create a partition of size 50Mb, <size> will take the value of 50
+  
+5. `parted` can also be run in an interactive format. Operations to manage the disk partitions can be performed by entering appropriate commands in the interactive session. 
+  `help` command in the interactive session shows a list of all possible disk management operations which can be performed.
+```
+  $ sudo parted
+  GNU Parted 3.3
+  Using /dev/sda
+  Welcome to GNU Parted! Type 'help' to view a list of commands.
+  (parted) print  # prints the partition table of the default selected disk - /dev/sda                                                  
+  Model: ATA VBOX HARDDISK (scsi)
+  Disk /dev/sda: 53.7GB
+  Sector size (logical/physical): 512B/512B
+  Partition Table: msdos
+  Disk Flags: 
+
+  Number  Start   End     Size    Type     File system  Flags
+   1      1049kB  53.7GB  53.7GB  primary  ext4         boot
+
+  (parted) select /dev/sdb  # change the current disk on which operations have to be performed                                                
+  Using /dev/sdb
+  (parted) quit  # exit the interactive session
+```
+
+### Syntax Forms:
+```
+parted [options] [device [command [options...]...]]
+```
+  
+### Options:
+|**Short Flag**   |**Long Flag**   |**Description**   |
+|:---|:---|:---|
+|-h|--help|displays a help message listing all possible `commands [options]`|
+|-l|--list|lists partition layout on all block devices|
+|-m|--machine|displays machine parseable output|
+|-v|--version|displays the version|
+|-a|--align|set alignment type for newly created partition. It can take the following values:<br /> `none`: Use the minimum alignment allowed by the disk type<br /> `cylinder`: Align partitions to cylinders<br /> `minimal`: Use minimum alignment as given by the disk topology information<br /> `optimal`: Use optimum alignment as given by the disk topology information|
