WebDAV File Downloader and Uploader Script

SLT Life Hacks

This script downloads a file from a specified URL, splits it into 500MB parts using 7-Zip, creates a folder on a WebDAV server, and uploads the split parts to that folder.

Prerequisites

Ensure you have the following installed on your Ubuntu server:

1. 7-Zip:

   sudo apt-get update
   sudo apt-get install p7zip-full

2. cURL:

   sudo apt-get install curl

3. jq:

   sudo apt-get install jq

Usage

1. Download the Script

   Save the following script as webdav_upload.sh:

   #!/bin/bash
   
   # Variables (modify these)
   WEB_DAV_URL="https://your-webdav-server.com/remote.php/webdav"
   WEB_DAV_USERNAME="your-username"
   WEB_DAV_PASSWORD="your-password"
   
   # Function to sanitize file names
   sanitize() {
     echo "$1" | tr -cd '[:alnum:]._-'
   }
   
   # Prompt the user to enter the download URL
   read -p "Please enter the download URL: " DOWNLOAD_URL
   
   # Check if the download URL is provided
   if [ -z "$DOWNLOAD_URL" ]; then
     echo "No download URL provided. Exiting."
     exit 1
   fi
   
   # Extract file name from URL and sanitize it
   FILE_NAME=$(basename "$DOWNLOAD_URL")
   FILE_NAME_WITHOUT_QUERY="${FILE_NAME%%\?*}"
   SANITIZED_FILE_NAME=$(sanitize "$FILE_NAME_WITHOUT_QUERY")
   
   # Download the file
   wget -O "$SANITIZED_FILE_NAME" "$DOWNLOAD_URL"
   
   # Check if download was successful
   if [ $? -ne 0 ]; then
     echo "Failed to download the file."
     exit 1
   fi
   
   # Split the file into 500MB parts
   7z a -v500m "${SANITIZED_FILE_NAME}.7z" "$SANITIZED_FILE_NAME"
   
   # Create a folder on the WebDAV server
   FOLDER_NAME="${SANITIZED_FILE_NAME%.*}"
   ENCODED_FOLDER_NAME=$(echo -n "$FOLDER_NAME" | jq -sRr @uri)
   curl -u "$WEB_DAV_USERNAME:$WEB_DAV_PASSWORD" -X MKCOL "$WEB_DAV_URL/$ENCODED_FOLDER_NAME/"
   
   # Check if folder creation was successful
   if [ $? -ne 0 ]; then
     echo "Failed to create folder on WebDAV server."
     exit 1
   fi
   
   # Upload the split parts to the WebDAV server
   for PART in "${SANITIZED_FILE_NAME}.7z".*; do
     ENCODED_PART_NAME=$(echo -n "$PART" | jq -sRr @uri)
     curl -u "$WEB_DAV_USERNAME:$WEB_DAV_PASSWORD" -T "$PART" "$WEB_DAV_URL/$ENCODED_FOLDER_NAME/$ENCODED_PART_NAME"
     
     # Check if upload was successful
     if [ $? -ne 0 ]; then
       echo "Failed to upload $PART to WebDAV server."
       exit 1
     fi
   done
   
   # Clean up
   rm "$SANITIZED_FILE_NAME" "${SANITIZED_FILE_NAME}.7z".*
   
   echo "File downloaded, split, and uploaded successfully."

2. Make the Script Executable

   chmod +x webdav_upload.sh

3. Run the Script

   Execute the script and follow the prompt to enter the download URL:

   ./webdav_upload.sh

   You will be prompted to enter the download URL. The script will then download the file, split it, create a folder on the WebDAV server, and upload the split parts.

Configuration

Modify the following variables in the script to match your WebDAV server details:

• WEB_DAV_URL: The URL of your WebDAV server.
• WEB_DAV_USERNAME: Your WebDAV username.
• WEB_DAV_PASSWORD: Your WebDAV password.

Notes

• Ensure that the WebDAV server credentials are kept secure and not hardcoded in publicly accessible scripts.
• This script assumes that the WebDAV server and required packages are properly configured and accessible from the server where the script is run.
