 30 | 4cget downloads the files organized by boards and threads.
 31 | 
 32 | ```shell
 33 | root
 34 |   └───board
 35 |       └───thread
 36 |             └───files
 37 | ```
 38 | 
 39 | run from source code (Golang installation required).
 40 | 
 41 | ```shell
 42 | git clone https://github.com/SegoCode/4cget
 43 | cd 4cget\code
 44 | go run 4cget.go https://boards.4channel.org/w/thread/...
 45 | ```
 46 | Or better [donwload a binary](https://github.com/SegoCode/4cget/releases).
 47 | 
 48 | ### Available Parameters
 49 | 
 50 | `4cget` provides various parameters to customize its behavior. Below are detailed examples and explanations for each available option:
 51 | 
 52 | #### Basic Usage
 53 | 
 54 | Download all images from a thread:
 55 | 
 56 | ```shell
 57 | 4cget https://boards.4channel.org/w/thread/...
 58 | ```
 59 | 
 60 | #### Enable Monitor Mode
 61 | 
 62 | Use the `--monitor` flag to enable monitor mode, which checks for new files every specified number of seconds:
 63 | 
 64 | ```shell
 65 | 4cget https://boards.4channel.org/w/thread/... --monitor 10
 66 | ```
 67 | 
 68 | *In this example, `4cget` will check every 10 seconds for new images.*
 69 | 
 70 | ####  Add Delay Between Downloads
 71 | 
 72 | Use the `--sleep` flag to add a delay between downloads (useful to avoid rate-limiting):
 73 | 
 74 | ```shell
 75 | 4cget https://boards.4channel.org/w/thread/... --sleep 2
 76 | ```
 77 | 
 78 | *This adds a 2-second delay between each download.*
 79 | 
 80 | #### Use a Proxy Server
 81 | 
 82 | If you need to route your requests through a proxy server:
 83 | 
 84 | ```shell
 85 | 4cget https://boards.4channel.org/w/thread/... --proxy http://proxyserver:port
 86 | ```
 87 | 
 88 | #### Proxy Authentication
 89 | 
 90 | If your proxy server requires authentication:
 91 | 
 92 | ```shell
 93 | 4cget https://boards.4channel.org/w/thread/... --proxy http://proxyserver:port --proxyuser username --proxypass password
 94 | ```
 95 | 
 96 | #### Display Help Message
 97 | 
 98 | Use the `--help` flag to display the help message with all available options:
 99 | 
100 | ```shell
101 | 4cget --help
102 | ```
103 | 
104 | > [!NOTE]
105 | > All flags must be prefixed with `--`. For example, use `--monitor` instead of `-monitor`.

160 |   4cget [options] <thread_url>
161 | 
162 | Options:
163 |   --help                 Display this help message.
164 |   --monitor <seconds>    Enable monitor mode with interval in seconds.
165 |                          The program will check for new images every specified interval.
166 |   --sleep <seconds>      Sleep duration in seconds between downloads.
167 |                          Useful to avoid getting rate-limited by the server.
168 |   --proxy <proxy_url>    Proxy URL (e.g., http://proxyserver:port).
169 |   --proxyuser <user>     Proxy username for authentication.
170 |   --proxypass <pass>     Proxy password for authentication.
171 | 
172 | Examples:
173 | 
174 |   Basic usage:
175 |     4cget https://boards.4chan.org/w/thread/123456
176 | 
177 |   Enable monitor mode with a 60-second interval:
178 |     4cget --monitor 60 https://boards.4chan.org/w/thread/123456
179 | 
180 |   Use a proxy with authentication:
181 |     4cget --proxy http://proxyserver:port --proxyuser username --proxypass password https://boards.4chan.org/w/thread/123456
182 | 
183 |   Add delay between downloads to prevent rate-limiting:
184 |     4cget --sleep 2 https://boards.4chan.org/w/thread/123456
185 | 
186 | Note:
187 |   - Ensure that all flags are prefixed with '--'.
188 |   - The thread URL must be a valid URL from a supported site.
189 |   - Use '--sleep' to add delays between downloads to avoid getting rate-limited (HTTP 429 errors).
