Great question! Batch downloading those images from FTP based on your TXT file is totally doable with a few simple scripting steps. Here are three reliable methods you can use, depending on your operating system and tools available:

Method 1: Standard FTP Client with Batch Script (Cross-Platform) #

This uses the built-in FTP client that comes with most operating systems:

1. First, extract the TXT file from your compressed package. Let’s assume the extracted file is named image_paths.txt.
2. Generate a list of FTP get commands from the TXT file. Each line has the local filename first, then the remote path—we only need those two fields:
   • On Linux/macOS, run this in the terminal:

     awk '{print "get " $2 " " $1}' image_paths.txt > ftp_commands.txt
     

   • On Windows (PowerShell):

     Get-Content image_paths.txt | ForEach-Object { $parts = $_.Split(); "get $($parts[1]) $($parts[0])" } | Out-File -Encoding ASCII ftp_commands.txt
     

3. Edit the ftp_commands.txt file to add server connection details at the top, and a quit command at the end:

   open your-ftp-server.com
   your-ftp-username
   your-ftp-password
   # (all the generated get commands will be here)
   quit
   

4. Run the script:
   • Linux/macOS: ftp -n < ftp_commands.txt
   • Windows: ftp -s:ftp_commands.txt

Note: Storing passwords in plain text is insecure. For safer access, use a .netrc file (Linux/macOS) or configure saved FTP credentials (Windows).

Method 2: Using lftp (Linux/macOS/WSL) #

lftp is a powerful, script-friendly FTP client that handles batch operations smoothly. Install it first with sudo apt install lftp (Debian/Ubuntu) or brew install lftp (macOS):

1. Extract your image_paths.txt file.
2. Run this command (replace placeholders with your FTP details):

   lftp -u your-username,your-password your-ftp-server.com -e "$(awk '{print "get " $2 " " $1}' image_paths.txt); quit"
   

You can omit the password from the command to be prompted for it, or store credentials securely in ~/.lftprc.

Method 3: Using curl (Cross-Platform) #

curl works with FTP and is widely available across systems:

1. Extract image_paths.txt.
2. Run this loop to download each file:
   • Linux/macOS:

     while read -r local_file remote_path hash; do
       curl ftp://your-username:your-password@your-ftp-server.com$remote_path -o "$local_file"
     done < image_paths.txt
     

   • Windows PowerShell:

     $ftpPrefix = "ftp://your-username:your-password@your-ftp-server.com"
     Get-Content image_paths.txt | ForEach-Object {
         $parts = $_.Split()
         curl "$ftpPrefix$($parts[1])" -o $parts[0]
     }
     

For better security, use curl --netrc to pull credentials from a .netrc file instead of hardcoding them.
