Continuing with this series of du alternatives, today we will discuss a ncurses based disk usage utility that can be run on a remote server set-up which does not have a graphical environment. The command line utility we are about to discuss is **ncdu**. - -### ncdu – Ncurses Based du Alternative ### - -The command line utility ncdu is nothing but a curses based version of the standard du command.

If you press yes, the directory will be deleted from the system. - -**4. Show Percentage Of Total Disk Consumption By Each Directory** - -Press g to display percentage of total disk consumption by each directory. - -Here is an example : - -![](http://mylinuxbook.com/wp-content/uploads/2013/10/ncdu-4.png) - -So you can see that percentage consumption of total disk for each entry is displayed in the second column of output. - -**5.
