I am currently preparing for a new job and cleaning up my dotfile repository. During the process, I had the idea that it would be nice to create a list of amazing tools, aliases, functions, and recommendations together.

I will start.

First, here is a list of nice tools to apt-get install or brew install that I can wholeheartedly recommend:

• nvim is just an amazing text editor.
• fzf is a very good fuzzy finder util. For example, you can quickly find files with it.
• eza is a good ls replacement (and the successor of exa).
• bat is a great replacement for cat with nice integrations and many options.
• stow is great for managing your dotfiles. Thanks to @TangibleLight for telling me about it some while ago. I really love it.
• tmux is a terminal multiplexer, i.e. you can have many sessions in one single terminal window. It's easy to use and super helpful. (When on a mac, I prefer iTerm tabs, though.)
• nvm is practically a must if you are working with Node.
• glow is an excellent markdown reader.
• tldr is a nice man replacement. (You must run tldr -u after installing it to update available texts.)
• z, an amazing tool for switching directories quickly.

Also, I can recommend Oh My ZSH! which I have been using for years.

Here is a small list of aliases I enjoy (I have 100+ aliases and I tried to pick some others may enjoy as well):

# Serve current dir
alias serve="npx serve ."

# What's my IP?
alias ip="curl --silent --compressed --max-time 5 --url 'https://ipinfo.io/ip' && echo ''"

# This should be the default
alias mkdir="mkdir -p"

# Nice git helpers
alias amend="git add . && git commit --amend --no-edit"
alias nuke="git clean -df && git reset --hard"

# Make which more powerful
which='(alias; declare -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot'

# This saves so many keystrokes, honestly
alias -- +x="chmod +x"

# Turns your path into a nice list and prints it
alias path='echo -e ${PATH//:/\\n}'

# Map over arguments and run a command
# Usage: map <command>
# Example: ls | map cat
alias map="xargs -n1"

And, finally, here are some fun functions:

# Get cheat sheets for almost anything!
# https://github.com/chubin/cheat.sh
cheat() {
    WITH_PLUS=$(echo $@ | sed 's/ /+/g')
    CAT_TOOL=$(command -v batcat || command -v bat || command -v cat)
    curl "cheat.sh/$WITH_PLUS" | $CAT_TOOL
}

# Send everything to /dev/null
nullify() {
  "$@" >/dev/null 2>&1
}

# Create a new dir and enter it
mk() {
  mkdir -p "$@" && cd "$_"
}

# Create a data URL from a file
# Source: https://github.com/mathiasbynens/dotfiles/blob/master/.functions
data-url() {
	local mimeType=$(file -b --mime-type "$1");
	if [[ $mimeType == text/* ]]; then
		mimeType="${mimeType};charset=utf-8";
	fi
	echo "data:${mimeType};base64,$(openssl base64 -in "$1" | tr -d '\n')";
}

Hey all, not-a-networks-guy here.

I've currently got an rpi set up running pihole natively (not in a container) for ad and website blocking reasons. (Using port 80, no TLS) I've used the pihole localdns feature to set an internal hostname for that ip (me.lan).

On the same pi, I have podman "set up" to run FreshRSS, and I'm getting more and more annoyed about using the port # to access it. (me.lan:12345) I'd like to set up a reverse proxy (probably Traefik) in a container to redirect internally, but considering that port 80 is taken (by pihole, outside of podman) I don't see a way to direct traffic from the pihole to Traefik.

I'd really rather not reconfigure the whole setup to use containers.... I'm lazy, and also prefer my dns resolver to have the least amount of overhead possible. Is configuring the router an option here, or is the only way to achieve what I'm looking for an overhaul of the pi and containers?

If I've missed any pertinent details, let me know and I'll update here.

Gonna try and put this into words.

I am pretty familiar with bash and python. used both quite a bit and feel more or less comfortable with them.

My issue is I often do a thing where if I want to accomplish a task that is maybe a bit complex, I feel like I have to wind up making a script, let's call it hello_word.sh but then I also make a script called .hello_world.py

and basically what I do is almost the first line of the bash script, I call the python script like ./hello_world.py $@ and take advtange of the argparse library in python to determine what the user wants to do amongst other tasks that are easier to do in python like for loops and etc.

I try to do the meat of the logic in the python scripts before I write to an .env file from it and then in the bash script, I will do

set -o allexport
source "${DIR}"/"${ENV_FILE}"
set +o allexport

and then use the variable from that env file to do the rest of the logic in bash.

why do I do anything in bash?

cause I very much prefer being able to see a terminal command being executed in real-time and see what it does and be able to Ctrl+c if I see the command go awry.

in python, you can run a command with subprocess or other similar system libraries but you can't get the output in real-time or terminate a command preemptively and I really hate that. you have to wait for the command to end to see what happened.

But I feel like there is something obvious I am missing (like maybe bash has an argparse library I don't know about and there is some way to inject the concept of types into it) or if there is another language entirely that fits my needs?
