Commands and Advanced Usage

HTTrack can also be used from the command line for advanced users who prefer automation or scripting. Here are some essential command-line options:

• Setting the Mirror Depth:

• Use the -r or --depth option followed by a number to specify the depth to which HTTrack should follow links. For example: httrack [URL] -r3

This command will mirror the website up to a depth of 3 link levels.

• Limiting Download Speed:

To limit the download speed, you can use the --limit-rate option. Specify the desired speed in bytes per second (e.g., 50KB/s): httrack [URL] --limit-rate=50K

• Setting User Agent:

You can set a custom User-Agent header using the --user-agent option to make your requests appear as if they’re coming from a different browser or device: httrack [URL] --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.0.0 Safari/537.36"

• Resuming an Interrupted Download:

• If a download gets interrupted, you can resume it using the --continue option: httrack --continue

HTTrack will pick up where it left off and complete the mirroring process.

• Updating an Existing Mirror:

• To update an existing mirrored website with new content from the source, use the --update option followed by the URL: httrack --update [URL]

This command will fetch and synchronize any new content since your last download.

• Logging and Verbose Output:

• If you need more detailed information during the mirroring process, you can enable verbose output with the -v or --verbose option: httrack [URL] -v

This will display real-time information about the download progress.

• Custom Configuration File:

• HTTrack allows you to use a custom configuration file to specify options. Use the --config option followed by the path to your configuration file: httrack [URL] --config myconfig.txt

Your configuration file should contain the desired options and their values, one per line.

• Limiting the Number of Connections:

• To control the number of simultaneous connections to the server, use the --max-connections option: httrack [URL] --max-connections=4

This can help you balance download speed and server load.

• Setting Timeouts:

Customize the timeout values for various aspects of the download process using options like --sockettimeout, --timewait, and --retries.

• Forcing IPv4 or IPv6:

To force HTTrack to use either IPv4 or IPv6, use the --disable-ipv6 or --disable-ipv4 options, respectively: httrack [URL] --disable-ipv6

Example Scenarios:

Scenario 1: Mirror a Website to a Custom Location

httrack [URL] -O /path/to/destination/folder

This command will mirror the website specified by [URL] and save the contents to the /path/to/destination/folder.

Scenario 2: Mirror a Website with Specific File Types

httrack [URL] "+*.jpg +*.png +*.pdf"

This command will mirror the website while downloading only .jpg, .png, and .pdf files.

Scenario 3: Update an Existing Mirror

httrack --update [URL]

This command will update an existing mirrored website with new content from the specified URL.

Scenario 4: Set a Custom User Agent

httrack [URL] --user-agent="MyCustomUserAgent"

This command will send requests to the website with the custom User-Agent header “MyCustomUserAgent.”
