I want to view the unallocated free space on my hard disk through terminal. I've burned my brains searching the internet for a possible solution, but all in vain.

I used all sorts of commands like dfdufdiskpartedetc. It tells me about the disks that are mounted and unmounted, but what about the unallocated space that I've left free? Use GNU parted and print free command:. If you are using the result in any calculations, make sure to trim the trailing characters. Since we're talking about free available space, we should talk about sectors, since no partitioning or sizing of sectors is done. For us human beings this doesn't make much sense.

To have human-readable information we must translate this number into bytes. So, we have a disk already partitioned and we want to know how much space we may use. I personally don't like the parted solution because my brain-memory for commands is already taken.

There is also cfdiskwhich gives you free space. It will gives you the number of sectors still how to see free space in linux. We still have sectors at bytes each. So, because you love terminal inhiw knows now? In addition to all the answers about how to find hoow space, you may also have space allocated to an LVM volume but not actually in use.

You can list physical volumes with the pvdisplay and see which volume groups each physical volume is associated with. If a physical volume isn't associated with any volume group, it's safe to reallocate or destroy.

Assuming that it it is associated with a volume group, the next step is to use vgdisplay to show your those. Among other things, this will show if you have any free "physical extents" — blocks of storage you can assign to a logical volume. You can get this in a concise form with vgs :. If I did, that last number would be bigger than zero. This is important, because that free space is invisible to dudfand the like, and also will show up as an allocated partition if you are using fdisk or another partitioning tool.

While using the disk utility graphically, it shows disk space used by all filesystem and it uses commands in the terminal such as df -H. In other words, it uses powers ofnot Note: there is difference between -h and -H. Now check the last cylinder value and subtract ljnux from the total cylinder value. Note: the cylinder value shows up in df -H as a power of or it might also show up using df -ha power of I had just the same trouble with fedora 26 and LVM partitions, it seems I forgot check something during the installation, So, my 15G root directory has been increased to G like Jn needed.

You just need to use options. For instance: df -h will print you those information in "human-readable" form. The "free space" should be some unused partition or lack of. So command automatically align epace and you'll get linx gaps between parts. There are many articles in net why need to do so.

The reason is that it gives solution with less errors. That was many years ago. Now I spacce know is there errors seee if you do all without any gaps. But first. But is first part begins always with sector. So call expert part you may shift it to 0. But spaec recomended to do so if you plan to boot from this disk. If only for data you'll gain 1 Mb additional disk space. This is spaace MBR space. But some see them. Seee you don't sure it use msdos. While format the block size is bytes logical physical one is bytes.

T was many discussion about that. It's lead to disk what are the 5 hawaiian islands. But you'll give some free disk space too especially when you have many small size files. You disk will fill more compactly. How to add more followers on twitter if you ho already partitioned ho with filled them with data and maybe installed OS you maybe want to do so, it was very problems to do.

But is possible for Linux. For Windows no You must save backup and mbr too, write UUID every part then use fdisk and format as setting right UUID and LABEL for every part restore mbr with dd command and if you don't do any wrong all will be work as before but without any gaps.

May be i think this is where what is a ethical consumer terminals falls short. I soace lots of ffree and used their many combinations, but no result. No, fdisk is showing disk partitions. If no free space is shown then you don't have any.

2) Show numbering of on-disk partitions

Mar 15,  · You can see the first Free Space which refers to the unallocated space that I explained before for the first default partition. Also notice that unallocated space has no numbering. In the following example, there is no partition on the hard disk and so it displays only unallocated space (free space). See that there is no numbering. The simplest way to show unallocated free space in a single command: $ sudo sfdisk --list-free /dev/sdX (Add the --quiet option if you don't need the extra info about sector size, etc.).

The df and du commands report on disk space usage from within the Bash shell used on Linux, macOS, and many other Unix-like operating systems. Bash contains two useful commands related to disk space. To find out the available and used disk space, use df disk filesystems, sometimes called disk free.

Type df and press enter in a Bash terminal window to get started. Using df without any options will display the available and used space for all mounted filesystems. At first glance, it might look impenetrable, but it is quite easy to understand. You can replace the 1K block counts with more useful output by using the -B block size option. These letters represent the kilo, mega, giga, tera, peta, exa, zeta, and yotta values from the multiple of scale.

For example, to see the disk usage figures in megabytes, you would use the following command. Note there is no space between the B and M. The -h human readable option instructs df to use the most applicable unit for the size of each filesystem.

In the next output note that there are filesystems with gigabyte, megabyte and even kilobyte sizes. If you need to see the information represented in numbers of inodes, use the -i inodes option. An inode is a data structure used by Linux filesystems to describe files and to store metadata about them. On Linux, inodes hold data such as the name, modification date, position on the hard drive, and so on for each file and directory.

Unless told not to, df will provide information on all of the mounted file systems. This can lead to a cluttered display with a lot of output. If you use the new Ubuntu snap method of installing applications, you can acquire a lot of these. We can tell df to exclude filesystems of a specific type.

To do so, we need to know what type of filesystem we wish to exclude. The -T print-type option will give us that information. It instructs df to include the type of filesystem in the output. We can exclude them with the following command:. That gives us a more manageable output. To get a total, we can add the --total option. We can ask df to only include filesystems of a particular type, by using the -t type option.

If we want to see the sizes for a set of filesystems, we can specify them by name. Drive names in Linux are alphabetical.

Partitions are numbered. We tell df to return information on a particular filesystem by passing the name of the filesystem as a command parameter. So to look at all partitions on the first drive, we could use:. We can ask df to report on a set of named filesystems. To further customize the display, we can tell df which columns to include. To do so use the --output option and provide a comma-separated list of the required column names. Make sure not to include any spaces in the comma separated list.

Long commands are perfect candidates to be turned into an alias. We can create an alias dfc for df custom by typing the following and pressing Enter:. Typing dfc and pressing enter will have the same effect as typing in the long command. To make this alias permanent add it to your. If you want to take the opposite approach and have df return all the information it possibly can use the -a all option and the --output option as shown below.

The -a all option asks df to include every filesystem, and using the --output option without a comma-separated list of columns causes df to include every column. Piping the output from df through the less command is a convenient way to review the large amount of output this can produce.

We can use the du command to show which folders are holding the most data. Issuing the du command with no options will display a list of all directories and sub-directories below the directory the du command was issued in.

If you do this from your home folder the listing will be very long. The output format is very simple. Each line shows the size and name of a directory. By default, the size is shown in 1K blocks. To force du to use a different block size, use the -B block size option. To use 1M blocks, use this command:. Just like df , du has a human-readable option, -h , which uses a range of block sizes according to the size of each directory.

The -s summarize option gives a total for each directory without displaying the sub-directories within each directory. The Picture folder holds the most data by far. We can ask du to sort the folders in size from largest to smallest. By refining the information returned by df and du it is easy to find out how much hard disk space is in use, and to discover what is taking up that space. You can then make an informed decision about moving some data to other storage, adding another hard drive to your computer or deleting redundant data.

These commands have a lot of options. We described the most useful options here, but you can see a complete listing of the options for the df command and for the du command in the Linux man pages.
