If you’re no longer interested in being part of a Discord server, you can leave the server to stop further engaging with it. We’ll show you how to do this in Discord on desktop, web, and mobile. When you leave a server, Discord no longer sends you notifications from that server. You also can’t post any messages in that server, and it will disappear from your sidebar.

[mai mult...]The du (disk usage) command summarizes directory trees’ sizes, including all of their contents and individual files’ sizes on Linux and Unix-like systems such as macOS. It helps track down space hogs. In other words, we can list directories and files that consume large amounts of space on a hard disk drive. Let us see the ncdu command, a curses-based version of the well-known du command.
Open the Terminal application and then type commands as per your distro. For instances, Debian/Ubuntu Linux users try the apt command/apt-get command as follows:
sudo apt install ncdu
Try the apk command to install ncdu including man pages on Alpine Linux:
# apk add ncdu ncdu-doc
Use the pacman command:
sudo pacman -S ncdu
We use the zypper command:
sudo zypper in ncdu
Turn on EPLE repo for RHEL/CentOS and then run the yum command:
sudo yum install ncdu
Fedora Linux user simply run the dnf command:
sudo dnf install ncdu
First, install Homebrew on macOS to use the brew package manager and then type:
brew install ncdu
Or use the following when using macports:
sudo port install ncdu
Type the following pkg command:
sudo pkg install ncdu
Execute the pkg_add command:
doas pkg_add ncdu
The basic syntax for ncdu is:
ncdu
ncdu [options] [directories]
Press q to exit to the shell. The ncdu can give information about any directory trees. For example:
ncdu /etc/
ncdu /tmp/
ncdu /nfs
ncdu $HOME
We can enable extended information mode by passing the -e:
ncdu -e
When ou want to scan a full filesystem, your root filesystem, for example, then you’ll want to pass the -x:
sudo ncdu -x /
On large Unix and Linux file servers, scanning a whole directory may take a while. So what you can do is review a directory and export the results for later viewing:
sudo ncdu -1xo- / | gzip >my_root_export.gz
Later after some time, we can use zcommands to read gzip compressed text files on a fly and pipe it out to the ncdu as follows:
ls -l my_root_export.gz
zcat my_root_export.gz | ncdu -f-
The -f option load the given file, which has earlier been created with the -o option. If FILE is equivalent to -, the file is read from standard input (pipe).
It is also possible to scan a system remotely using the ssh command. Then browse through the files locally:
ssh -C user@system ncdu -o- / | ncdu -f-
ssh -C vivek@192.168.2.17 ncdu -o- / | ncdu -f-
Turn on color option:
ncdu --color dark
ncdu --color dark -x /
We can exclude files that match PATTERN:
ncdu --exclude '*.c'
ncdu -x --exclude '/dir1' --exclude '/dir2' /
Follow symlinks and count the size of the file they point to:
ncdu -L
ncdu -L dir1

By far the most annoying new “feature” of Windows 11 is the truncated context menu you get when right-clicking on anything. Where prior versions of Windows showed all of your options, including different programs that could open a file, the new menus are limited to just a handful of choices, and not necessarily the ones you want.
For example, when I installed Notepad++, a popular text editor, and then right-clicked on a .txt file, I was not shown the program as an option for opening it. Even under the “Open with” submenu, only the Windows notepad appeared. Sure, you can see the full list of options if you click “Show more options,” but that’s an extra click you didn’t have to make in Windows 10.
