# 1. Right-click on ~/Downloads → Folder Actions Setup
# 2. Attach workflow: "Compress items in folder"
# 3. Files added to Downloads auto-compress
# 4. Saves space and keeps Downloads organized

AppleScript: Deep Application Control

AppleScript is Apple's scripting language designed to control applications and automate complex workflows.

AppleScript Basics

# Basic AppleScript syntax
tell application "Finder"
    activate
    make new Finder window
    set target of front window to path to documents folder
end tell

# Getting user input
display dialog "Enter your name:" default answer ""
set userName to text returned of result
display notification "Hello, " & userName

# Working with files
tell application "Finder"
    set selectedItems to selection
    repeat with itemRef in selectedItems
        -- Process each selected file
    end repeat
end tell

Example: Batch File Renamer

-- Batch Rename Script
tell application "Finder"
    set sourceFolder to folder "Macintosh HD:Users:username:Documents:ToRename:"
    set fileList to every file of sourceFolder
    
    repeat with aFile in fileList
        set originalName to name of aFile
        set newName to "Processed_" & originalName
        set name of aFile to newName
    end repeat
    
    display notification "Renamed " & (count fileList) & " files"
end tell

Example: Automated Backup Script

-- Simple Backup to External Drive
tell application "Finder"
    set sourceFolder to folder "Macintosh HD:Users:username:Documents:"
    set backupFolder to folder "Backup:Documents Backup:"
    
    -- Use shell for robust copy
    do shell script "rsync -av --delete " & POSIX path of sourceFolder & " " & POSIX path of backupFolder
    
    display notification "Backup completed!"
end tell

Shell Scripting for Mac

Shell scripting (bash, zsh) provides powerful system-level automation for Mac.

macOS-Specific Shell Features

#!/bin/zsh
# macOS-specific commands

# Open apps and files
open -a "Safari"
open "~/Documents/report.pdf"

# Use macOS utilities
mdfind "kind:pdf modified:>today"  # Spotlight search
mdls document.pdf  # Show file metadata

# Notification
osascript -e 'display notification "Backup complete" with title "Mac Automation"'

Example: Daily Cleanup Script

#!/bin/zsh
# daily-cleanup.sh

# Clean Downloads of files older than 30 days
find ~/Downloads -type f -mtime +30 -empty -delete
find ~/Downloads -type f -mtime +90 -delete

# Organize Desktop
mkdir -p ~/Desktop/ToProcess
find ~/Desktop -maxdepth 1 -name "*.txt" -exec mv {} ~/Desktop/ToProcess/ \;

# Empty trash securely
rm -rf ~/.Trash/*

echo "Daily cleanup complete" | osascript -e 'display notification'

Scheduling with launchd

# Create ~/Library/LaunchAgents/com.user.daily-cleanup.plist




    Label
    com.user.daily-cleanup
    ProgramArguments
    
        /bin/zsh
        /Users/username/scripts/daily-cleanup.sh
    
    StartCalendarInterval
