##### send_file
send_file allows you to send different type's of files, e.g. photos, stickers, audio, media, etc. [see more](https://core.telegram.org/bots/api#sending-files).
It's recommended to use the _absolute path name_ (starting with `/`). A relative path is threated as relative to `data-bot-bash/upload` as default UPLOADDIR.
send_file allows can send different type's of files, e.g. photos, stickers, audio, media, etc.
[see Telegram API documentation](https://core.telegram.org/bots/api#sending-files).
It's recommended to use __absolute path names__ (_starting with `/`_), as relative path names are threated as __relative to UPLOADDIR__ `data-bot-bash/upload`!
For security reasons the following restrictions apply:
- absolute path name must match the shell _regex_ FILE_REGEX (not file glob!)
- path must not start with "." and not contain ".."
- absolute path name must match the __shell regex__ `FILE_REGEX` (_not file glob_)
- path must not start with `./` and not contain `../`
*usage:* send_file "${CHAT[ID]}" "file" "caption"
*example:*
```bash
# recommended absolute path
# recommended: absolute path
send_file "${CHAT[ID]}" "/home/user/dog.jpg" "My Dog"
# relative to default dir: data-bot-bash/upload/dog.jpg
# relative to UPLOADDIR: data-bot-bash/upload/dog.jpg
send_file "${CHAT[ID]}" "dog.jpg" "My Dog"
# change to personal dir
# change to personal upload dir
UPLOADDIR="/home/user/myuploaddir"
# relative to changed dir: /home/user/myuploaddir/dog.jpg
# relative to personal upload dir: /home/user/myuploaddir/dog.jpg
send_file "${CHAT[ID]}" "dog.jpg" "My Dog"
