send_message "${USER[ID]}" "lol"
```
2016-01-19 20:53:45 +01:00
To send images, videos, voice files, photos ecc use the ```send_photo``` function:
```
2016-01-19 20:53:45 +01:00
send_file "${USER[ID]}" "/home/user/doge.jpg" "Lool"
```
2016-01-19 20:53:45 +01:00
To send custom keyboards use the ```send_keyboard``` function:
```
2016-01-19 20:53:45 +01:00
send_keyboard "${USER[ID]}" "Text that will appear in chat?" "Yep" "No"
```
2016-01-19 20:53:45 +01:00
To send locations use the ```send_location``` function:
```
send_location "${USER[ID]}" "Latitude" "Longitude"
```
To forward messages use the ```forward``` function:
```
forward "${USER[ID]}" "from_chat_id" "message_id"
```
To send a chat action use the ```send_action``` function.
Allowed values: typing for text messages, upload_photo for photos, record_video or upload_video for videos, record_audio or upload_audio for audio files, upload_document for general files, find_location for locations.
```
send_action "${USER[ID]}" "action"
```
To create interactive chats, write (or edit the question script) a normal bash (or C or python) script, chmod +x it and then substitute ./question @ line 49 with the command you usually use to start the script.
The text that the script will output will be sent in real time to the user, and all user input will be sent to the script (as long as it's running or until the user kills it with /cancel).
To open up a keyboard in an interactive script, print out the keyboard layout in the following way:
```
2016-01-22 18:54:08 +01:00
echo "Text that will appear in chat? mykeyboardstartshere \"Yep, sure\" \"No, highly unlikely\""
```
2016-01-19 20:53:45 +01:00
Same goes for files:
```
echo "Text that will appear in chat? myfilelocationstartshere /home/user/doge.jpg"
```
And locations:
```
2016-01-19 20:53:45 +01:00
echo "Text that will appear in chat. mylatstartshere 45 mylongstartshere 45"
```
2016-01-19 20:53:45 +01:00
You can combine them:
```
2016-01-22 18:54:08 +01:00
echo "Text that will appear in chat? mykeyboardstartshere \"Yep, sure\" \"No, highly unlikely\" myfilelocationstartshere /home/user/doge.jpg mylatstartshere 45 mylongstartshere 45"
```

2016-01-06 14:04:24 +01:00
Once you're done editing start the bot with ```tmux new-session -d -s bashbot "./bashbot.sh"```.
2016-01-06 14:05:39 +01:00
To stop the bot run ```tmux kill-session -t bashbot```.
2016-01-06 14:04:24 +01:00
If some thing doesn't work as it should, debug with ```bash -x bashbot.sh```.
That's it!
