Image Processing on Linux

Bash Script to Resize and Move Images

Overview

This Bash script continuously monitors a specified directory using inotifywait. When new image files are added, it resizes them to a specified dimension (1024x768), renames them with a timestamp, and moves them to a destination directory (Resimler). If non-image files are added, they are deleted.

Requirements

# Install the `inotify-tools` package for `inotifywait`.
sudo apt install inotify-tools -y

Bash Script

#!/bin/bash

src_directory="/path/to/source/directory"
dest_directory="/path/to/destination/directory/Resimler"
max_width=1024
max_height=768

while true; do
    inotifywait -e create "$src_directory"

    for file in "$src_directory"/*; do
        if [[ -f "$file" && $(file --mime-type -b "$file") == image/* ]]; then
            timestamp=$(date +"%Y%m%d%H%M%S")
            new_filename="${timestamp}_$(basename "$file")"
            convert "$file" -resize "${max_width}x${max_height}" "$dest_directory/$new_filename"
            rm "$file"
            echo "[$(date)] $file resized and moved."
        elif [[ -f "$file" ]]; then
            rm "$file"
            echo "[$(date)] $file deleted as it is not an image."
        fi
    done
done

Usage

1. Modify the src_directory and dest_directory variables according to your requirements.
2. Optionally adjust max_width and max_height for the desired image dimensions.
3. Run the script.

Bash Script to Upload Resized Images

Overview

This Bash script extends the previous script by adding functionality to upload resized images to a specified URL using curl.

Requirements

# Install the `inotify-tools` package for `inotifywait`.
sudo apt install inotify-tools -y
# Install the `curl` command.
sudo apt install curl -y

Bash Script

#!/bin/bash

src_directory="/path/to/source/directory"
dest_directory="/path/to/destination/directory/Resimler"
max_width=1024
max_height=768
upload_url="https://example.com/upload"  # Replace with your upload URL

while true; do
    inotifywait -e create "$src_directory"

    for file in "$src_directory"/*; do
        if [[ -f "$file" && $(file --mime-type -b "$file") == image/* ]]; then
            timestamp=$(date +"%Y%m%d%H%M%S")
            new_filename="${timestamp}_$(basename "$file")"

            convert "$file" -resize "${max_width}x${max_height}" "$dest_directory/$new_filename"

            curl -X POST -F "file=@$dest_directory/$new_filename" "$upload_url"

            rm "$file"
            echo "[$(date)] $file resized, moved, and uploaded."
        elif [[ -f "$file" ]]; then
            rm "$file"
            echo "[$(date)] $file deleted as it is not an image."
        fi
    done
done

Usage

1. Modify the src_directory, dest_directory, max_width, max_height, and upload_url variables according to your requirements.
2. Run the script.
