How It Works: 1. First Backup: Creates a simple .bak file (e.g., file.txt → file.txt.bak). 2. Subsequent Backups: Adds a timestamp before .bak to avoid overwriting existing backups (e.g., file.txt → file.txt_20241130_123456.bak). Examples: • First run: bu file.txt Creates: file.txt.bak • Subsequent runs: bu file.txt Creates: file.txt_20241130_12…

New simple file backup command.sh

bak() {
    # If a basic .bak file doesn't exist, create it
    if [ ! -e "$1.bak" ]; then
        cp "$1" "$1.bak"
    else
        # Otherwise, create a timestamped backup with .bak at the end
        cp "$1" "$1_$(date +%Y%m%d_%H%M%S).bak"
    fi
}

# fancier
# simple file backup in place for not crushing yourself when you save over the current file
bak() {
    if [ $# -eq 0 ]; then
        echo "Usage: bu <file_or_directory>"
        return 1
    fi
    
    if [ ! -e "$1" ]; then
        echo "❌ Error: '$1' does not exist"
        return 1
    fi
    
    if [ ! -e "$1.bak" ]; then
        cp -ai "$1" "$1.bak"
        echo "💾 Backup created: $1.bak"
    else
        timestamp="$(date +%Y%m%d_%H%M%S)"
