Soluții pentru problemele tale IT
In timpul unei videoconferinte sau a unui webinar, cand avem pornita o prezentare cu Google Slides putem sa beneficiem de functia Q&A session integrata in aplicatia Google Slides.
[mai mult...]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
