The name “ncdu” stands for “NCurses disk use. It utilizes an ncurses interface to supply the disk usage information. “Curses”, as you probably know, has no connection to nasty language. Instead, when related to Linux, “curses” is a term associated to “cursor”– that little marker on your screen that indicates where you are currently working.

ncdu
on the command line, simply type “ncdu”. You’ll see a display that looks something like what is revealed listed below as soon as it has run a series of commands to rapidly collect the required file size data to create the listing for you.ncdu 1.17 ~ Use the arrow keys to browse, press? for aid–/ home/shs —————————————————————- 61.3 GiB [###########]/ fampix 5.1 GiB []/ pix 1.5 GiB []/. cache 483.1 MiB []/. local 311.3 MiB []/ videos 152.9 MiB []/ nextjs 85.3 MiB []/. mozilla 78.2 MiB []/ homebrew 59.4 MiB []/ Desktop
You can navigate up and down the listing using your down arrow and up arrow secrets. If you push the enter key when you’re sitting on a line that represents a directory, you will move into that directory.

Nevertheless, it displays file sizes based upon a binary-based numbering system with file sizes like 5.1 GiB, 10.2 MiB and 23.9 KiB. The second area below compares these measurements to numbers based upon powers of 10 (our normal numbering system). These tebibyte(TiB ), gibibyte (GiB ), mebibyte(MiB)and kibibyte (KiB)numbers are all based on powers of two. They are close in size to terabytes, gigabytes, megabytes and kilobytes, but are all significantly bigger. One kibibyte equals 1,024 bytes– larger than kilobyte at 1,000 bytes. One gibibyte equates to 1,073,741,824 bytes– a fair bit bigger than a gigabyte at 1,000,000,000. Other alternatives The ncdu tool supplies a variety of extra alternatives. For example, you can change to noting files by name by pressing “n”, and you can erase a file by pressing”d”and responding to the ask for confirmation. You can bring up more details on a file or directory by moving to its name in the listing and pressing”i “. You can toggle in between viewing file sizes and disk usage by pushing” a”. The display will start with the possibly bigger disk use sizes. The sizes revealed will typically differ since disk usage counts the full size of the last block even if the file isn’t fully utilizing it. If you begin ncdu with the -e choice, you can type”m “to toggle in between the … Source
