Linux

I've got the standard ones (l, ll, ls) to be forms of ls -flags

df = df -h
mv = mv -i
rm = rm -i
nix-switch = sudo nix-rebuild --switch flake .
nix-upd = nix flake update
systat = systemctl status
sysena = sudo systemctl enable
systop = sudo systemctl stop

alias cat lolcat
alias ccat whatever ohmyzsh does for their colorize extension, I know it’s a function alias

alias clear="clear; fastfetch"
alias sudo="doas"
alias clr="clear"
alias kx="killall Xwayland"
alias vpython="~/newVenv/bin/python"
alias vpip="~/newVenv/bin/pip"

I mainly use an alias to ssh into my server and another to stream lofi girl audio with mpv

I don't like having to renavigate to my project directory in a new terminal:

alias clone='(pwd | urxvt & disown $!)'

Takes my current directory and opens it in my terminal. Then it disowns that new terminal process, so if I close the current terminal the new one doesnt disappear with it.

For system updates:

[ -r /etc/os-release ] && . /etc/os-release
case "$ID" in
  arch|archarm)
    if which paru > /dev/null 2>&1; then
      alias updates='echo Using paru; paru'
    else
      alias updates='echo Using pacman; sudo pacman -Syu --noconfirm'
    fi
    ;;
  debian|ubuntu)
    alias updates='echo Using apt dist-upgrade; sudo apt update && sudo apt dist-upgrade -y'
    ;;
esac

This is a separate reply since I didn't know that you can include shell functions here.

I made this little function read_latest_log() because I just want to "read the latest log file" in a directory full of timestamped log files. I made a helper function separator_line_with_text() to help with the output, basically setting off the file-info portion (just the filename for now) from the file contents.

# # separator_line_with_text
# # Centers text in a separator line
# #
# # Usage:
# # separator_line_with_text «separator_char» «text»
separator_line_with_text() {
local separator_char="$1"
local contents_str="$2"

# Calculate separator_length
local separator_length=$(( $(tput cols) - 2 - ${#contents_str} ))

# Calculate the width of the left and right parts of the separator line
local half_line_width=$(( (${separator_length}) / 2 ))

# Construct the separator line using the $separator_char and $contents_str
for ((i = 0; i « half_line_width; i++))
do
echo -n ${separator_char}
done

echo -n ${contents_str}

for ((i = 0; i < half_line_width; i++))
do
echo -n ${separator_char}
done

echo ""
}

# # read_latest_log
# # Reads the latest log file with a timestamp in the filename.
# #
# # Usage:
# # read_latest_log [[«name_filter»] «extension»] «separator» «timestamp_field_number»
read_latest_log () {
  # Check if the function has sufficient parameters
  if [[ $# -lt 2 ]]; then
    echo "Error: insufficient parameters."
    echo "Usage: read_latest_log [[«name_filter» = *] [«extension» = log] «separator» «timestamp_field_number»"
    return 1
  fi

  # Supposing only two parameters are provided
  # «name_filter» parameter is "*"
  # «extension» parameter is "log"
  if [[ $# -eq 2 ]]; then
    local name_filter="*"
    local extension="log"
    local separator="$1"
    local field="$2"
  fi

  # Supposing only three parameters are provided,
  # assume that the «name_filter» parameter is "*"
  if [[ $# -eq 3 ]]; then
    local name_filter="*"
    local extension="$1"
    local separator="$2"
    local field="$3"
  fi

  # If all parameters are provided, assign them accordingly
  if [[ $# -eq 4 ]]; then
    local name_filter="$1"
    local extension="$2"
    local separator="$3"
    local field="$4"
  fi

  # Find all log files with the specified extension, sort them based on the separator and field
  local log_files=$(find . -type f -name "${name_filter}.${extension}" | sort -n -t "${separator}" -k "${field}")

  # If no log files are found, display a message and return
  if [[ -z "$log_files" ]]; then
    echo "No log files found."
    return 0
  fi

  # Get the latest log file and its full path
  local latest_log_file=$(echo "$log_files" | tail -1)
  local full_path=$(realpath "$latest_log_file")

  # Define the strings for the separator line and
  # calculate the appropriate length of the separator line
  local contents_str=" Contents "
  local separator_char="—"

  separator_line_with_text ${separator_char} ""
  separator_line_with_text " " ${full_path}
  separator_line_with_text ${separator_char} ${contents_str}
  cat "$(echo "$log_files" | tail -1)"
}

Sorry for all the edits, for some reason anything that looks like an HTML tag gets erased.

I've got aliases for every faltpak app I launch in the terminal for instance I've got code for vscodium or steam for well steam for example, I also alias some system commands so I have an update-grub, update, etc...

I also alias LSD to LS for obvious reasons.

https://github.com/K1aymore/Nixos-Config/blob/74f38451c42990756128f0b3980221bc0290b4db/term/aliases.nix

alias upgrade="sudo dnf upgrade --yes && flatpak update && flatpak remove --unused"

Or something like that, also a dnf remove unused command in there. Writing this from my phone so might be written wrong.

(NOTE: A lot of my more interesting "aliases" are actually short functions, but I'm keeping myself to alias.)

Some of mine that I haven't seen yet:

# Simple python calculator
alias pycalc='python3 -ic "
from math import *\nimport cmath as C
try:
    import numpy as np
except:
    pass
i, j = 1j, 1j
"'

# Defaults
alias cp='cp --interactive --reflink=auto'
alias gcc='gcc -fdiagnostics-color=auto'
# Lemmy doesn't handle ampersands in codeblocks correctly
alias rg='rg --max-columns=$((COLUMNS > 60 && ! ZSH_SUBSHELL ? COLUMNS - 30 : 0))'
alias rj='rg --json'
alias rm='rm -s'
alias rscp='rsync -azP --human-readable --info=flist0,progress2,stats1'
alias rust-c='rustc --out-dir build -O'

# Shorter forms

alias mount='acol mount'
alias nmap='acol nmap'
alias ping='GRC ping'
alias ps='GRC ps --columns $COLUMNS'
alias traceroute='GRC traceroute'

Some random ones I created over the last week or so:

alias clipboard='xclip -selection clipboard' # Allows me to pipe output directly to my keyboard. good for pwd for example.

Function allows me to get tldr and cheat responses to commands quickly
function cht() {
curl cheat.sh/$1
}

Easy calculator so that I can do math w/o launching a specific app
function calc() {
echo "scale=3; $@" | bc
}

alias forgethist=unset HISTFILE

Useful when I run the same two commands 20 times in a row
