  multifiledownloader -d ~/Downloads/custom-dir -u "url1,url2,url3"
  

• Clean destination directory before downloading:

  multifiledownloader --clean -u "url1,url2"
  

• Set custom number of workers:

  multifiledownloader -w 4 -u "url1,url2"
  

Reading URLs from a File

You can read URLs from a file where each URL is on a new line:

# Create a file with URLs
$ cat > urls.txt << EOF
https://example.com/file1.txt
https://example.com/file2.txt
EOF

# Download using the file
$ multifiledownloader -w 8 --dest ~/Downloads --urls "$(cat urls.txt | tr '\n' ',' | sed 's/,$//g')"

Shell Completion

Generate shell completion scripts for your shell:

# Bash
multifiledownloader --completion bash | sudo tee /usr/local/etc/bash_completion.d/multifiledownloader

# Zsh or to a directory in your $fpath
multifiledownloader --completion zsh | sudo tee /usr/local/share/zsh/site-functions/_multifiledownloader

# Fish
multifiledownloader --completion fish | sudo tee /usr/local/share/fish/vendor_completions.d/multifiledownloader.fish

# PowerShell
multifiledownloader --completion powershell | Out-File -FilePath $PROFILE\multifiledownloader.ps1

# Elvish
multifiledownloader --completion elvish | tee $HOME/.elvish/completions/multifiledownloader.elv

Troubleshooting

Common Issues

1. Permission Errors

   • Ensure you have write permissions to the destination directory
   • Use --clean flag to remove existing files before downloading

2. Network Issues

   • Check if URLs are accessible
   • Use fewer workers if experiencing connection timeouts

3. Progress Bar Issues

   • Progress bars may not display correctly in some terminals
   • Try using a different terminal emulator if experiencing issues
