Inshellisense is teaching me a lot. :) It's an autocompleter.

As someone who has to do installs and admin a lot at work I'm constantly dealing with yum/dnf. I cry when I have to work with AIX.

nmap *your_local_ip_address*

for example

nmap 192.168.1.43/24 will show you what devices are connected to the local network, and what ports are open there. really useful, for example, when you forgot the address of your printer or raspi yet again.

you can also use it to understand what ports on your computer are open from an attacker's perspective, or simply to figure out what services are running (ssh service).

losetup

it's useful for dealing with virtual disk images. like a real physical hard disk, but it's a file on the computer. you can mount it, format it, and write it to a real physical disk.

it's sometimes used with virtual machines, with iso images, or when preparing a bootable disk.

On the subject of editors, joe is just awesome: lightweight, powerful, had coffee coloring and line numbers, and you can choose it with Ctrl+C:)

edir, can use GUI editors too.

glances! Way better than top and does a bazillion cool things!

paste. I don't think a lot of people know this command, but it can be handy at times

ia: internetarchive https://archive.org/developers/internetarchive/cli.html cli tool, i only use it for downloads, it can a bit more than the eye meets first, like accepting a wildcard to download certain files or specify other stuff. I have an incomplete script to help me with that, which I want to share in the future. The only problem is, that the internetarchive at archive.org is often very slow at downloading.
