Termux Automation Scripts 2025: 5 Time-Saving Bash Scripts for Android Power Users

 

Automation is the cornerstone of productivity for power users, and Termux unlocks this capability directly on Android devices. In 2025, with mobile workflows becoming more complex, Bash scripting in Termux provides an unmatched way to execute routine tasks, boost efficiency, and extend device functionality beyond traditional boundaries. This article explores five essential Bash scripts for Termux, complete with code examples, detailed explanations, and real-world use cases.

Why Termux Automation Matters in 2025

Termux is a powerful terminal emulator and Linux environment app for Android. With Bash scripting, users can automate tedious, repetitive tasks, saving time and minimizing errors. Automation scripts help streamline backups, boost productivity, keep data organized, and even act as the backbone for mobile development and IoT control. The scripts highlighted here are handpicked for their impact and practicality—each can be extended or customized to fit your workflow as you grow more comfortable with Termux automation.

Introduction to Bash Scripting in Termux

Bash is a Unix shell and scripting language that powers nearly every Linux system, including the environment Termux emulates on Android. Scripts are simply text files filled with commands that the shell interprets and executes, allowing you to automate repeatable actions.

To create a script on Termux:

nano myscript.sh

Add your commands, save (Ctrl+O), and exit (Ctrl+X). Make the script executable:

chmod +x myscript.sh

Run it with:

./myscript.sh

Scripts can be scheduled, run in the background, or triggered by events using Termux’s API or cron utilities.

Script 1: Automatic File Backup to Cloud Storage

Purpose: Back up important folders (photos, documents, notes) to Google Drive using the rclone tool.

Script Example: auto-backup.sh

#!/usr/bin/env bash

# Directory to back up
SOURCE_DIR="$HOME/Documents"
# Rclone remote name (configured with rclone)
REMOTE_NAME="gdrive"
# Destination path on Google Drive
DEST_DIR="Backup/Documents"
# Log file for error tracking
LOG_FILE="$HOME/backup.log"

echo "Starting backup of $SOURCE_DIR to $REMOTE_NAME:$DEST_DIR"
date >> "$LOG_FILE"
rclone sync "$SOURCE_DIR" "$REMOTE_NAME:$DEST_DIR" --progress --log-file "$LOG_FILE"
echo "Backup complete."

Explanation

• Rationale: Manual backups risk data loss from accidental deletion, theft, or device failure. Automating the backup process protects your documents with zero effort required.

• How it helps: This script guarantees important files are always backed up. Users only need to set up rclone with Google Drive once. Afterward, backups take a single tap—schedule it for nightly execution for true automation.

• Customizations: Easily modify SOURCE_DIR and DEST_DIR for other folders or cloud services supported by rclone.

• Power user tip: Trigger this script on device charging or low battery for efficient usage.

Script 2: Scheduled Wi-Fi Toggle for Battery Optimization

Purpose: Conserve battery life by disabling Wi-Fi during specified hours and re-enabling it when you need it.

Script Example: wifi-opt.sh

#!/usr/bin/env bash

# Requires termux-api: pkg install termux-api

# Scheduled hours (24h format)
START_HOUR=0     # Midnight
END_HOUR=6       # 6 AM

CURRENT_HOUR=$(date +%H)

if [[ $CURRENT_HOUR -ge $START_HOUR && $CURRENT_HOUR -lt $END_HOUR ]]; then
  termux-wifi-enable false
  echo "Wi-Fi disabled for battery optimization."
else
  termux-wifi-enable true
  echo "Wi-Fi enabled during active hours."
fi

Explanation

• Rationale: Many people forget to turn off Wi-Fi at night, draining battery pointlessly.

• How it helps: This script automatically toggles Wi-Fi based on the time, ensuring you save power without needing to remember manually. Use Termux’s termux-api for full integration with Android features.

• Customizations: Adjust START_HOUR and END_HOUR to fit your schedule. Add more logic to disable other features like Bluetooth or sync.

Script 3: Daily Notes Collection System

Purpose: Quickly append notes to a daily text file for personal journaling, reminders, or work logs.

Script Example: quick-note.sh

#!/usr/bin/env bash

NOTES_DIR="$HOME/Notes"
TODAY_FILE="$NOTES_DIR/$(date +%F).txt"

mkdir -p "$NOTES_DIR"
echo "Enter your note:"
read NOTE
echo "[$(date +%T)] $NOTE" >> "$TODAY_FILE"
echo "Note saved to $TODAY_FILE."

Explanation

• Rationale: Keeping a daily log or journal boosts productivity and helps with record-keeping.

• How it helps: Instead of opening an app, running this script instantly prompts you for input and saves your note with a timestamp to a date-stamped file.

• Customizations: Integrate with voice input, sync notes to cloud, or schedule automatic backups using previous script.

Script 4: Bulk Image Resizer & Optimizer

Purpose: Compress and resize all images in a folder for web upload, sharing, or storage reduction.

Script Example: img-resize.sh

#!/usr/bin/env bash

# Requires imagemagick: pkg install imagemagick

SRC_DIR="$HOME/Pictures/ToResize"
OUT_DIR="$HOME/Pictures/Resized"
WIDTH=1024
QUALITY=80

mkdir -p "$OUT_DIR"
for IMG in "$SRC_DIR"/*.{jpg,png}; do
  BASENAME=$(basename "$IMG")
  convert "$IMG" -resize ${WIDTH}x -quality $QUALITY "$OUT_DIR/$BASENAME"
  echo "$IMG resized and optimized."
done
echo "All images processed."

Explanation

• Rationale: Large images take up space, slow down uploads, and consume data.

• How it helps: Instantly resize and optimize dozens or hundreds of images for web pages, cloud upload, or sharing. Termux makes this possible directly from your phone using imagemagick.

• Customizations: Change WIDTH, QUALITY, or file types for your needs; add watermarking for creative projects.

Script 5: Mobile Package Update & Cleanup Manager

Purpose: Regularly update and clean Termux packages to keep the terminal lean and secure.

Script Example: pkg-maintenance.sh

#!/usr/bin/env bash

echo "Updating all Termux packages..."
pkg update -y && pkg upgrade -y

echo "Cleaning unused packages and caches..."
pkg autoremove -y
pkg clean

echo "System maintenance complete."

Explanation

• Rationale: Frequent updates are crucial for security and stability; cleaning unneeded files saves storage.

• How it helps: This script runs all necessary commands to keep your Termux environment in optimal health, all at once—no manual input needed.

• Customizations: Extend to include checks for specific security patches or package installs.

Final Tips for Termux Power Users

• Scheduling: Use Termux’s cron-like schedulers (e.g., cronie or Termux Task Scheduler apps) to set automation scripts to run at fixed intervals or based on events.

• Integration: Combine scripts for multi-step workflows. For example, run quick-note.sh and then auto-backup.sh before bed.

• Notifications: Use Termux’s notification API (termux-notification) to report status after script completion, failure, or upon user input.

• API Access: Termux provides a wide range of Android API integrations for battery, sensors, location, and more, making it a powerful hub for mobile automation.
