Thank you for rating this article.

If you are a Linux user, you know how important the Terminal is to your compute world.  Now there are a bunch of different Terminals in Linux, this article is not about that, but I like Tilix the best: 

sudo apt install tilix

Instead, this article is about apps that run in the terminal.

Let's jump right in.  These are in no particular order.

#1: htop

My first one is htop, a cross-platform interactive process viewer.  The current releases support Linux, FreeBSD, OpenBSD, DragonFly BSD, MacOSX and Solaris.  You can find more info here: https://htop.dev

Installation is easy: 

sudo apt install htop

Example output:

#2: trash-cli

One of the things I don't like (sometimes) about the 'rm' [remove] command, is that when invoked it removes whatever you specify and it is gone forever.  What if you could delete things to your trash bin?  That is where trash-cli comes in.

trash-cli trashes files recording the original path, deletion date, and permissions. It uses the same trashcan used by KDE, GNOME, and XFCE, but you can invoke it from the command line (and scripts).

It provides these commands:

trash-put           trash files and directories.
trash-empty         empty the trashcan(s).
trash-list          list trashed files.
trash-restore       restore a trashed file.
trash-rm            remove individual files from the trashcan.


You can find trash-cli here: https://github.com/andreafrancia/trash-cli

Installation is easy: 

sudo apt install trash-cli

Example output:

#3: ranger

ranger is a console file manager with VI key bindings, so it is VIM like. It provides a minimalistic and nice curses interface with a view on the directory hierarchy. Just use the arrow keys to navigate your directory structure and even open files!

You can find more information on ranger here: https://github.com/ranger/ranger

Installation is easy: 

sudo apt install ranger

Example output:

#4: neofetch and pfetch

I put these together, and you can use either.  These are simple  tools that display information about your operating system, software and hardware. 

Neofetch is probably better is you want to customize the output, and the one I like.

You can find more information on neofetch here: https://github.com/dylanaraps/neofetch

Installation is easy: 

sudo apt install neofetch

Example output:

#5: youtube-dl

This is a simple utility that allows you to download YouTube videos to your system.  You just need this terminal based app and the link to the YouTube video you want.  It is a great way to take videos off the net with you or backup your videos.

You can find more information on youtube-dl here: https://youtube-dl.org

Installation is easy: 

sudo curl -L https://yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl

sudo chmod a+rx /usr/local/bin/youtube-dl

Example output:

#6: ncdu

I am always wanting to know my disk storage status, especially on small capacity Linux systems.  ncdu is a disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don't have an entire graphical setup available, but it is a useful tool even on regular desktop systems. Ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

You can find more information on ncdu here: https://dev.yorhel.nl/ncdu

Installation is easy: 

sudo apt install ncdu

When first run, it scans the disk.

Example output:

#7: hollywood

This is a fun app that makes your screen look impressive for background to videos or meetings or whatever.  Other than that it is useless.

You can find more information on hollywood here: https://snapcraft.io/hollywood

Installation is easy: 

sudo apt install hollywood
