+# Step-by-Step Guide to Determining Application Sizes on Mac via Terminal (zsh)
+
+This guide helps you determine the size of all installed applications, programs, and packages on your Mac. You will create a shell script that searches various sources and compiles the results into a sorted file.
+
+**Important:** This process can take up to 1 hour, as it first calculates all sizes and then sorts them.
+
+## Table of Contents
+- Step 1: Create the Script with nano
+- Step 2: Add Script Content
+- Step 3: Make the Script Executable
+- Step 4: Install Necessary Dependencies
+- Step 5: Run the Script
+- Step 6: Verify the Results
+- License
+
+## Step 1: Create the Script with nano
+Open the Terminal and create a new script file using nano:
+
+```zsh
+nano ~/application_size_checker.sh
+```
+
+## Step 2: Add Script Content
+Copy the following content and paste it into the nano editor:
+
+```zsh
+#!/bin/zsh
+
+# Define output file
+OUTPUT=~/Desktop/application_size_sorted.txt
+echo "Determining application sizes on your Mac" > $OUTPUT
+echo "Created on: $(date)" >> $OUTPUT
+echo "--------------------------------------------" >> $OUTPUT
+
+# Function to add sections
+add_section() {
+    echo -e "
+$1" >> $OUTPUT
+    echo "--------------------------------------------" >> $OUTPUT
+    shift
+    for line in "$@"; do
+        echo "$line" >> $OUTPUT
+    done
+}
+
+# 1. Homebrew Formulas
+brew list --formula | parallel -j4 '
+    formula_path=$(brew --prefix {})

+    else
+        size="{}: Path not found"

+    echo "$size"
+' | sort -hr > brew_formula_sizes.txt
+
+brew_formula_sizes=$(cat brew_formula_sizes.txt)
+add_section "Homebrew Formulas:" "${(@f)brew_formula_sizes}"

+    app_name=$(basename "{}")
+    size=$(du -sh "{}" 2>/dev/null | awk "{print "${app_name}: "$1}")
+    echo "$size"
+' | sort -hr)
+
+add_section "Applications Found via sudo find:" "${(@f)found_apps_sizes}"
+
+# 6. Packages Installed via pkgutil
+pkgutil --pkgs | parallel -j4 '
+    pkg_info=$(pkgutil --pkg-info "{}" 2>/dev/null)
+    if [ $? -eq 0 ]; then
+        install_location=$(echo "$pkg_info" | grep "volume:" | awk "{print \$2}")
+        if [ -d "$install_location" ]; then
+            size=$(du -sh "$install_location" 2>/dev/null | awk "{print "{}: "$1}")
+        else
+            size="{}: Installation location not found"
+        fi
+    else
+        size="{}: Information not available"
+    fi
+    echo "$size"
+' | sort -hr > pkgutil_pkgs_sizes.txt
+
+pkgutil_pkgs_sizes=$(cat pkgutil_pkgs_sizes.txt)
+add_section "Packages Installed via pkgutil:" "${(@f)pkgutil_pkgs_sizes}"
+
+# 7. Applications Listed via system_profiler
+system_profiler SPApplicationsDataType -json | jq -r '.SPApplicationsDataType[] | "\(.name): \(.size)"' | sort -hr > system_profiler_apps_sizes.txt
+system_profiler_apps_sizes=$(cat system_profiler_apps_sizes.txt)
+add_section "Applications Listed via system_profiler:" "${(@f)system_profiler_apps_sizes}"
+
+# Completion message
+echo "The sizes of the applications have been saved to $OUTPUT."
+```
+
+Save and Exit the Editor:
+
+    Press `Ctrl + O` and then `Enter` to save the file.
+    Press `Ctrl + X` to exit the editor.
+
+## Step 3: Make the Script Executable
+
+Make the script executable by running the following command in the Terminal:
+
+```zsh
+chmod +x ~/application_size_checker.sh
+```
+
+## Step 4: Install Necessary Dependencies
+
+For processing the JSON output from `system_profiler`, we use `jq`. Ensure it is installed by running:
+
+```zsh
+brew install jq
+```
+
+Additionally, ensure that `parallel` is installed. If not, install it with:
+
+```zsh
+brew install parallel
+```
+
+If you don't have Homebrew installed, you can install it by following the instructions at [https://brew.sh/](https://brew.sh/).
+
+## Step 5: Run the Script
+
+Execute the script by running:
+
+```zsh
+~/application_size_checker.sh
+```
+
+## Step 6: Verify the Results
+
+After the script has finished running, you will find a file named `application_size_sorted.txt` on your Desktop. This file contains a complete list of all detected applications and packages with their respective sizes, sorted in descending order.
