Linux

I don't see anyone mentions htop. So, I will:) Just works, could be installed in any distro. Much more friendly than top but isn't bloated with features as some other alternatives are.

I find myself using tldr a lot since finding out about it. It's just so useful for commands that I don't use enough to commit to memory.

ip eg:

# ip a
# ip a a 192.168.1.99/24 dev enp160

The first incantation - ip address (you can abbreviate whilst it is unambiguous) gets you a quick report of interfaces, MAC, IPs and so on. The second command assigns another IP address to an interface. Handy for setting up devices which don't do DHCP out of the box or already have an IP and need a good talking to.

Oh and you can completely set up your IP stack, interfaces and routing etc with it. Throw in nft or iptables (old school these days - sigh!) for filtering and other network packet mangling shenanigans.

sshfs

jq?

Honorary mention to < and &

nano was and still is vital to me learning and using linux, I will not learn how to use vim so if the distro forces it to be default im not using it.

Why is editing text so convoluted for seemingly no reason.. also hate that vim must be used for certain files.

After spending years dealing with shady freeware and junk software on windows, I was floored by how easy and nonchalantly I was able to set up a simple security camera on my PC

I'm a big fan of screen because it will let me run long-running processes without having to stay connected via SSH, and will log all the output.

I do a lot of work on customers' servers and having a full record of everything that happened is incredibly valuable for CYA purposes.

ncdu

I know tmux is incredibly popular, but a good use case for it that isn’t common is teaching people how to do things in the terminal. You can both be attached to the same tmux session, and both type into the same shell.

all of them

Underrated Both linked projects have over 60k+ stars on GitHub

Discovered about rg recently and it is cool!

yq is crazy cool for converting between different text-based data formats such as yaml, json, xml, csv and others, and it has a super nice pretty-printing function as well. I use it all the time!

Just be aware that your distroy might come with a yq variant too, but possibly one that isn't as powerful as the one I linked. I know this to be true at least for Ubuntu.

Underrated? I'd say lftp is the best FTP command line client there is. And Midnight Commander is a very very good file browser. I don't see either praised enough.

• xargs
• parallel
• PXE (ohai cobbler)
• tee
• task-spooler (ts aka tsp)
• rpm -V

Nothing new, just forgotten.

Using rust rewrite of coreutils you can cp -g to see progress. Set an alias :)

I love ncdu for seeing where all my storage is being taken up.

tmsu is pretty cool - it creates a little db and uses that to track tags on your files without ever touching them. It also has it's own little tag based filesystem.

CTRL-L to clear your terminal output. Or type clear
