Bash Scripting Examples: Scripts You'll Build

The best way to learn bash scripting is through real projects. Here are practical examples you'll encounter in most courses, with code you can try right now.

Example 1: Automated Backup Script

This script creates timestamped backups of a directory:

#!/bin/bash

# Automated backup script
SOURCE_DIR="$1"
BACKUP_DIR="$HOME/backups"
TIMESTAMP=$(date +%Y%m%d_%H%M%S)

# Validate input
if [[ -z "$SOURCE_DIR" ]]; then
    echo "Usage: $0 <source_directory>"
    exit 1
fi

if [[ ! -d "$SOURCE_DIR" ]]; then
    echo "Error: $SOURCE_DIR is not a directory"
    exit 1
fi

# Create backup directory if it doesn't exist
mkdir -p "$BACKUP_DIR"

# Create compressed backup
BACKUP_FILE="$BACKUP_DIR/backup_${TIMESTAMP}.tar.gz"
tar -czf "$BACKUP_FILE" -C "$(dirname "$SOURCE_DIR")" "$(basename "$SOURCE_DIR")"

echo "Backup created: $BACKUP_FILE"
echo "Size: $(du -h "$BACKUP_FILE" | cut -f1)"

Example 2: Log Analyzer

Parse server logs and generate a summary report:

#!/bin/bash

# Log analyzer - summarize HTTP status codes
LOG_FILE="${1:-/var/log/nginx/access.log}"

if [[ ! -f "$LOG_FILE" ]]; then
    echo "Log file not found: $LOG_FILE"
    exit 1
fi

echo "=== Log Analysis Report ==="
echo "File: $LOG_FILE"
echo "Total requests: $(wc -l < "$LOG_FILE")"
echo ""

echo "Status code breakdown:"
awk '{print $9}' "$LOG_FILE" | sort | uniq -c | sort -rn | head -10

echo ""
echo "Top 5 requested URLs:"
awk '{print $7}' "$LOG_FILE" | sort | uniq -c | sort -rn | head -5

echo ""
echo "Requests per hour (last 24h):"
awk '{print $4}' "$LOG_FILE" | cut -d: -f2 | sort | uniq -c

Example 3: System Health Check

Monitor system resources and send alerts:

#!/bin/bash

# System health checker
THRESHOLD_CPU=80
THRESHOLD_MEM=90
THRESHOLD_DISK=85

check_cpu() {
    local cpu_usage
    cpu_usage=$(top -bn1 | grep "Cpu(s)" | awk '{print $2}' | cut -d. -f1)
    if [[ "$cpu_usage" -gt "$THRESHOLD_CPU" ]]; then
        echo "WARNING: CPU usage is ${cpu_usage}% (threshold: ${THRESHOLD_CPU}%)"
    else
        echo "OK: CPU usage is ${cpu_usage}%"
    fi
}

check_memory() {
    local mem_usage
    mem_usage=$(free | awk '/Mem/{printf("%.0f"), $3/$2*100}')
    if [[ "$mem_usage" -gt "$THRESHOLD_MEM" ]]; then
        echo "WARNING: Memory usage is ${mem_usage}% (threshold: ${THRESHOLD_MEM}%)"
    else
        echo "OK: Memory usage is ${mem_usage}%"
    fi
}

check_disk() {
    while read -r usage mount; do
        if [[ "$usage" -gt "$THRESHOLD_DISK" ]]; then
            echo "WARNING: Disk ${mount} is ${usage}% full (threshold: ${THRESHOLD_DISK}%)"
        fi
    done < <(df -h | awk 'NR>1{gsub(/%/,"",$5); print $5, $6}')
}

echo "=== System Health Report ==="
echo "Date: $(date)"
echo ""
check_cpu
check_memory
check_disk

These are the kinds of scripts you'll build throughout FreeAcademy's Interactive Bash Scripting course. Each module ends with a practical project like these.

Bash Scripting vs Python: Which Should You Learn First?

One of the most common questions is whether to learn Bash or Python first. Here's a quick comparison:

Aspect	Bash	Python
Best for	System automation, DevOps, file operations	Data processing, web apps, AI/ML
Learning curve	Moderate (quirky syntax)	Gentle (readable syntax)
Setup required	None (pre-installed on Linux/macOS)	Minimal (install Python)
Speed for shell tasks	Fastest — native to the terminal	Slower — needs subprocess calls
Complex logic	Gets messy beyond ~100 lines	Scales well to large programs
Job market	Required for DevOps/SRE roles	Required for nearly all dev roles

Our recommendation: If you work with servers, containers, or CI/CD pipelines, learn Bash first. It's the language your terminal speaks natively. Then add Python for more complex automation. Many DevOps professionals use both daily.

Common Bash Scripting Mistakes to Avoid

1. Forgetting to Quote Variables

# Wrong - breaks with spaces
files=$HOME/my documents
cd $files

# Right - handles spaces correctly
files="$HOME/my documents"
cd "$files"

2. Using Deprecated Syntax

# Old syntax - avoid
if [ $x == "test" ]

# Modern syntax - preferred
if [[ $x == "test" ]]

3. Ignoring Exit Codes

# Dangerous - continues after failure
rm important_file
do_next_thing

# Safe - check for errors
rm important_file || { echo "Failed to remove file"; exit 1; }

4. Not Using ShellCheck

Always run your scripts through ShellCheck (shellcheck.net) to catch common errors and bad practices. It's like a linter for shell scripts.

5. Hardcoding Paths

# Fragile
cd /home/john/scripts

# Robust
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
cd "$SCRIPT_DIR"

6. Not Using set -euo pipefail

# Without safety nets - errors go unnoticed
#!/bin/bash
rm "$file"
process_data

# With safety nets - script stops on errors
#!/bin/bash
set -euo pipefail
rm "$file"
process_data

Adding set -euo pipefail at the top of your scripts catches unset variables, failed commands, and broken pipes. It's considered a best practice for production scripts.
