Bashbot function reference
Send, forward, delete messages
To insert line brakes in a message or caption you can place \n in the text.
send_action
send_action shows users what your bot is currently doing.
usage: send_action "${CHAT[ID]}" "action"
"action": typing, upload_photo, record_video, upload_video, record_audio, upload_audio, upload_document, find_location.
alias: _action "action"
example:
send_action "${CHAT[ID]}" "typing"
send_action "${CHAT[ID]}" "record_audio"
send_normal_message
send_normal_message sends text only messages to the given chat.
usage: send_normal_message "${CHAT[ID]}" "message"
alias: _normal_message "message"
example:
send_normal_message "${CHAT[ID]}" "this is a text message"
send_markdownv2_message
send_markdownv2_message sends markdown v2 style messages to the given chat.
Telegram supports a new Markdown V2 Style which
has more formatting codes and is more robust, but incompatible with old telegram markdown style.
usage: send_markdownv2_message "${CHAT[ID]}" "markdown message"
example:
send_markdownv2_message "${CHAT[ID]}" "this is a markdown message, next word is *bold*"
send_markdownv2_message "${CHAT[ID]}" "*bold* __underlined__ [text](link)"
send_markdown_message
send_markdown_message sends markdown style messages to the given chat.
This is the old, legacy Telegram markdown style, retained for backward compatibility.
It supports a reduced set of Markdown only
usage: send_markdown_message "${CHAT[ID]}" "markdown message"
alias: _markdown "message"
example:
send_markdown_message "${CHAT[ID]}" "this is a markdown message, next word is *bold*"
send_markdown_message "${CHAT[ID]}" "*bold* _italic_ [text](link)"
send_html_message
send_html_message sends HTML style messages to the given chat.
Telegram supports a reduced set of HTML only
usage: send_html_message "${CHAT[ID]}" "html message"
alias: _html_message "message"
example:
send_normal_message "${CHAT[ID]}" "this is a markdown message, next word is <b>bold</b>"
send_normal_message "${CHAT[ID]}" "<b>bold</b> <i>italic><i> <em>italic>/em> <a href="link">Text</a>"
forward_message
forward_mesage forwards a message to the given chat.
usage: forward_message "chat_to" "chat_from" "${MESSAGE[ID]}"
old call: forward "${CHAT[ID]}" "$FROMCHAT" "${MESSAGE[ID]}"
alias: _forward "$FROMCHAT" "${MESSAGE[ID]}"

delete_message
A bot can only delete messages if he is admin of a Chat, if not he can delete his own messages only.
usage: delete_message "${CHAT[ID]}" "${MESSAGE[ID]}"
See also deleteMessage limitations
send_message
send_message sends any type of message to the given chat. Type of output is steered by keywords within the message.
The main use case for send_message is to process the output of interactive chats and background jobs. For regular Bot commands I recommend using of the dedicated send_xxx_message() functions from above.
usage: send_message "${CHAT[ID]}" "message"
example: - see Usage and Advanced Usage
File, Album, Location, Venue, Keyboard
send_file
send_file allows can send different type's of files, e.g. photos, stickers, audio, media, etc. see Telegram API documentation.
It's recommended to use absolute path names (starting with /), as relative path names are threated as relative to UPLOADDIR data-bot-bash/upload!
For security reasons the following restrictions apply:
- absolute path name must match the shell regex
FILE_REGEX(not file glob) - path must not start with
./and not contain../
usage: send_file "${CHAT[ID]}" "file" "caption"
example:
# recommended: absolute path
send_file "${CHAT[ID]}" "/home/user/dog.jpg" "My Dog"
# relative to UPLOADDIR: data-bot-bash/upload/dog.jpg
send_file "${CHAT[ID]}" "dog.jpg" "My Dog"
# change to personal upload dir
UPLOADDIR="/home/user/myuploaddir"
# relative to personal upload dir: /home/user/myuploaddir/dog.jpg
send_file "${CHAT[ID]}" "dog.jpg" "My Dog"
send_album
usage: send_album "${CHAT[ID]}" "URL1" "URL2" ... "URLn"
example:
send_album "$(getConfigKey "botadmin")" "http://www.rrr.de/slider/main-image1.jpg" "http://www.rrr.de/slider/main-image5.jpg"
send_location
usage: send_location "${CHAT[ID]}" "Latitude" "Longitude"
send_venue
usage: send_venue "${CHAT[ID]}" "Latitude" "Longitude" "Title" "Address" "foursquare id (optional)"
send_keyboard
Note: Since version 0.6 send_keyboard was changed to use native "JSON Array" notation as used from Telegram. Detection and emulation for old format will be removed after 1.0 release!
Example Keyboard Array definitions:
- yes no in two rows:
- OLD format: 'yes' 'no' (two strings)
- NEW format: '[ "yes" ] , [ "no" ]' (two arrays with a string)
- new layouts made easy with NEW format:
- Yes No in one row: '[ "yes" , "no" ]'
- Yes No plus Maybe in 2.row: '[ "yes" , "no" ] , [ "maybe" ]'
- number pad style keyboard: '[ "1" , "2" , "3" ] , [ "4" , "5" , "6" ] , [ "7" , "8" , "9" ] , [ "0" ]'
usage: send_keyboard "chat-id" "message" "keyboard"
alias: _keyboard "message" "keyboard"
example:
send_keyboard "${CHAT[ID]}" "Say yes or no" '[ "yes" , "no" ]' # in one row
send_keyboard "${CHAT[ID]}" "Say yes or no" '[ "yes" ] , [ "no" ]' # 2 rows
send_keyboard "${CHAT[ID]}" "Enter digit" '[ "1" , "2" , "3" ] , [ "4" , "5" , "6" ] , [ "7" , "8" , "9" ] , [ "0" ]'
_keyboard_yesno # see aliases
_keyboard_numpad
remove_keyboard
usage: remove_keybord "$CHAT[ID]" "message"
alias: _del_keyboard "message"
See also: Keyboard Markup
send_button
usage: send_button "chat-id" "message" "text" "URL"
alias: _button "text" "URL"
example:
send_button "${CHAT[ID]}" "MAKE MONEY FAST!!!" "Visit my Shop" "https://dealz.rrr.de"
send_inline_keyboard
Even its called keyboard, this function is different from send_keyboard. The main difference is that it's only possible to specify URL buttons, no Text Buttons and the Buttons must be an Array of Buttons as specified for Telegram InlineMarkup.
The inline buttons must be specified as a JSON string in the following format:
[ {"text":"text1", "url":"url1"}, ... {"text":"textN", "url":"urlN"} ]
Each button consists of a pair of text and URL values, sourrounded by '{ }', multiple buttons are separated by ',' and everything is wrapped in '[ ]'.
usage: send_inline_keyboard "chat-id" "message" "[ {"text":"text", "url":"url"} ...]"
alias: _inline_keyboard "[{"text":"text", "url":"url"} ...]"
example:
send_inline_keyboard "${CHAT[ID]}" "MAKE MONEY FAST!!!" '[{"text":"Visit my Shop", url"":"https://dealz.rrr.de"}]'
send_inline_keyboard "${CHAT[ID]}" "" '[{"text":"button 1", url"":"url 1"}, {"text":"button 2", url"":"url 2"} ]'
send_inline_keyboard "${CHAT[ID]}" "" '[{"text":"b 1", url"":"u 1"}, {"text":"b 2", url"":"u 2"}, {"text":"b 2", url"":"u 2"} ]'
See also Inline keyboard markup
Edit / Replace Messages
Edit a message means replace the content of the message in place. The message stay on the same position in the chat and keep the same message id.
There is no need to use the same format when replace a message, e.g. a message sent with send_normal_message can be replaced with
edit_markdown_message or edit_html_message and vice versa.
To replace a message you must know the message id of the the original message. The best way to get the message id is to save the value of
BOTSENT[ID] after sending the original message.
edit_normal_message
edit_normal_message replace a message with a text message in the given chat.
usage: edit_normal_message "${CHAT[ID]}" "MESSAGE-ID" "message"
example:
send_normal_message "${CHAT[ID]}" "this is a text message"
saved-id="${BOTSENT[ID]}"
edit_normal_message "${CHAT[ID]}" "${saved-id}" "this is another text"
edit_markdownv2_message
edit_markdownv2_message replace a message with a markdown v2 message in the given chat.
usage: edit_markdownv2_message "${CHAT[ID]}" "MESSAGE-ID" "message"
example:
send_normal_message "${CHAT[ID]}" "this is a text message"
saved-id="${BOTSENT[ID]}"
edit_markdownv2_message "${CHAT[ID]}" "${saved-id}" "this is __markdown__ *V2* text"
edit_markdown_message
edit_markdown_message replace a message with a markdown message in the given chat.
usage: edit_markdown_message "${CHAT[ID]}" "MESSAGE-ID" "message"
example:
send_normal_message "${CHAT[ID]}" "this is a text message"
saved-id="${BOTSENT[ID]}"
edit_markdown_message "${CHAT[ID]}" "${saved-id}" "this is *markdown* text"
edit_html_message
edit_html_message replace a message with a html message in the given chat.
usage: edit_html_message "${CHAT[ID]}" "MESSAGE-ID" "message"
example:
send_normal_message "${CHAT[ID]}" "this is a text message"
saved-id="${BOTSENT[ID]}"
edit_html_message "${CHAT[ID]}" "${saved-id}" "this is <b>html</b> text"
User Access Control
The following basic user control functions are part of the Telegram API. More advanced API functions are currently not implemented in bashbot.
kick_chat_member
If your Bot is a chat admin he can kick and ban a user.
usage: kick_chat_member "${CHAT[ID]}" "${USER[ID]}"
alias: _kick_user "${USER[ID]}"
unban_chat_member
If your Bot is a chat admin can unban a kicked user.
usage: unban_chat_member "${CHAT[ID]}" "${USER[ID]}"
alias: _unban "${USER[ID]}"
leave_chat
Your Bot will leave the chat.
usage: leave_chat "${CHAT[ID]}"
alias: _leave
if _is_admin ; then
send_markdown_message "${CHAT[ID]}" "*LEAVING CHAT...*"
leave_chat "${CHAT[ID]}"
fi
'See also kick Chat Member*
The following functions are bashbot only and not part of the Telegram API.
bot_is_admin
Return true (0) if bot is admin or creator of given chat.

user_is_allowed
Bashbot supports User Access Control, see Advanced Usage
usage: user_is_allowed "${USER[ID]}" "what" "${CHAT[ID]}"
example:
if ! user_is_allowed "${USER[ID]}" "start" "${CHAT[ID]}" ; then
send_normal_message "${CHAT[ID]}" "You are not allowed to start Bot."
fi
Inline Queries - answer direct queries to bot
Inline Queries allows users to interact with your bot directly without sending extra commands. As an answer to an inline query you can send back one or more results to the Telegram client. The Telegram client will then show the results to the user and let him select one.
answer_inline_query
answer_inline_query is provided for backward compatibility with older versions of bashbot. It send back only one response to an inline query.
usage: answer_inline_query "$i{QUERY[ID]}" "type" "type arg 1" ... "type arg n"
example: - see Advanced Usage
answer_inline_multi
anwser_inline_multi allows you to send back a list of responses. Responses must be separated by ','.
usage: answer_inline_multi "${iQUERY[ID]}" "res, res, ... res"
example:
# note the starting " and ending " !!
answer_inline_multi "${iQUERY[ID]}" "
$(inline_query_compose "1" "photo" "https://avatars0.githubusercontent.com/u/13046303") ,
...
$(inline_query_compose "n" "photo" "https://avatars1.githubusercontent.com/u/4593242")
"
inline_query_compose
inline_query_compose composes one response element to to send back.
usage: inline_query_compose ID type args ....
ID = unique ID for this response, 1-64 byte long
type = type of answer, e.g. article, photo, video, location ...
args = mandatory arguments in the order they are described in telegram documentation
Currently the following types and arguments are implemented (optional arguments in parenthesis)
"article"|"message" title message (parse_mode description)
"photo" photo_URL (thumb_URL title description caption parse_mode keyboard)
"gif" photo_URL (thumb_URL title caption parse_mode keyboard)
"mpeg4_gif" mpeg_URL (thumb_URL title caption parse_mode keyboard)
"video" video_URL mime_type thumb_URL title (caption parse_mode keyboard)
"audio" audio_URL title (caption parse_mode keyboard)
"voice" voice_URL title (caption parse_mode keyboard)
"document" title document_URL mime_type (caption description parse_mode)
"location" latitude longitude title
"venue" latitude longitude title (address foursquare)
"contact" phone first (last thumb)
"cached_photo" file (title description caption parse_mode keyboard)
"cached_gif" file (title caption parse_mode keyboard)
"cached_mpeg4_gif" file (title caption parse_mode keyboard)
"cached_sticker" file (keyboard)
"cached_document" title file (description caption description parse_mode keyboard)
"cached_video" file title (description caption description parse_mode keyboard)
"cached_voice" file title (caption parse_mode keyboard)
"cached_audio" file title (caption parse_mode keyboard)
see InlineQueryResult for more information about response types and their arguments.
Background and Interactive jobs
Background functions and interactive jobs extends the bot functionality to not only react to user input. You can start scripts for interactive chats and send messages based on time or other external events.
start_proc
startproc starts a script, the output of the script is sent to the user or chat, user input will be sent back to the script. see Advanced Usage
usage: start_proc "${CHAT[ID]}" "script"
alias: startproc "script"
example:
startproc 'examples/calc.sh'
check_proc
Return true (0) if an interactive script is running in the chat.
usage: check_prog "${CHAT[ID]}"
alias: checkprog
example:
if ! check_proc "${CHAT[ID]}" ; then
startproc "examples/calc.sh"
else
send_normal_message "${CHAT[ID]}" "Calc already running ..."
fi
kill_proc
Kill the interactive script running in the chat
usage: kill_proc "${CHAT[ID]}"
alias: killproc
example:
if check_proc "${CHAT[ID]}" ; then
killproc && send_message "${CHAT[ID]}" "Command canceled."
else
send_message "${CHAT[ID]}" "Command is not running."
fi
start_back
Starts a script as a background job and attaches a job name to it. All output from a background job is sent to the associated chat.
In contrast to interactive chats, background jobs do not receive user input and can run forever. In addition you can suspend and restart running jobs, e.g. after reboot.
usage: start_back "${CHAT[ID]}" "script" "jobname"
alias: background "script" "jobname"
example:
background "examples/notify.sh" "notify"
check_back
Return true (0) if an background job is active in the given chat.
usage: check_back "${CHAT[ID]}" "jobname"
alias: checkback "jobname"
example:
if ! checkback "notify" ; then
send_normal_message "${CHAT[ID]}" "Start notify"
background "examples/notify.sh" "notify"
else
send_normal_message "${CHAT[ID]}" "Process notify already running."
fi
kill_back
usage: kill_back "${CHAT[ID]}" "jobname"
alias: killback "jobname"
example:
checkback "notify"
if [ "$res" -eq 0 ] ; then
send_normal_message "${CHAT[ID]}" "Kill notify"
killback "notify"
else
send_normal_message "${CHAT[ID]}" "Process notify not run."
fi
send_interactive
Form version 0.80 on forward_message is used to forward messages to interactive job. It replaces the old 'inproc' commands used for TMUX. Usually a message is automatically forwarded in 'commands.sh', but you can forward messages while processing also or send your own messages.
usage: send_interactive "${CHAT[ID]}" "message"
replaces: incproc
jsshDB
Since output generated by JSON.sh is so handy to use in bash, we use the format for a simple keys/value file store. The file extensions is '.jssh' and for security reasons location of jssh files is restricted to BASHBOT_ETC and BASHBOT_DATA..
fast and slow operations
jsshDB files are simple text files and if you append a new Key/value pairs to the end of the file it overwrites an existing key/value pair. We use this behavior for "fast" file operations.
"fast functions" add a new key/value pair to the end of the file without deleting an existing one, this is fast but over (long) time the file grows infinity.
"slow functions" in contrast modify the key/value pairs in place and write the whole file back, this is slower but clean up the file. All previously added key/value pairs are replaced and only the last one is written back to the file.
fast functions:
jssh_insertKeyDB , jssh_addKeyDB , jssh_countKeyDB
slow functions:
jssh_writeDB, jssh_updateDB , jssh_deleteKeyDB, jssh_clearDB
File naming and locking
A jssh fileDB consists of two files which must reside inside BASHBOT_ETC or BASHBOT_DATA.
filename.jsshis a text file containing the key/value data in json.sh format.filename.jssh.flockis used for read/write locking with flock
Path names containing .. or not located in BASHBOT_ETC or BASHBOT_DATA are refused by jsshDB functions with an error.
Since version 0.94 jsshDB functions support file locking with flock. Write/update operations are serialised with flock to wait until previous operations are finished, see "man flock" for information. To avoid deadlocks we use a timeout of 10s for write and 5s for read operations.
Every jssh_*DB function exist as jssj_*DB_async also. In case flock is not availibe or you don't want locking, jssh_*DB_async functions without file locking will be used.
Example: for allowed file names:
# bashbot is installed in /usr/local/telegram-bot-bash, BASHBOT_ETC is not set.
"myfile" -> /usr/local/telegram-bot-bash/myfile.jssh
"addons/myfile" -> /usr/local/telegram-bot-bash/addons/myfile.jssh
"${DATADIR}/myfile" -> /usr/local/telegram-bot-bash/data-bot-bash/myfile.jssh
"/home/someuser/myfile" -> function returns false, nothing done.
jssh_newDB
Creates new empty jsshDB file if not exist.
usage: jssh_newDB "filename"
usage: jssh_newDB_async "filename"
jssh_clearDB
Delete all contents of jsshDB file.
usage: jssh_clearDB "filename"
usage: jssh_clearDB_async "filename"
jssh_checkDB
Check if DB name respects the rules mentioned above and print to STDOUT the real/final path to DB file. Used internally by all jssh DB functions, but can also used to get the real filename for a jssh DB.
An error is returned and nothing is printed if the given filename is not valid
usage: jssh_checkDB "filename"
usage: jssh_checkDB_async "filename"
if file=$(jssh_checkDB somename); then
echo "Final filename is ${file}"
else
echo "Something wrong with somename"
fi
# somename = data-bot-bash/somevalues
Final filename is data-bot-bash/somevalues.jssh
# somename = /home/someuser/myfile
Something wrong with /home/someuser/myfile
# somename = data-bot-bash/../../../somevalues
Something wrong with data-bot-bash/../../../somevalues
jssh_writeDB
Write content of an ARRAY into jsshDB file. ARRAY name must be declared with "declare -A ARRAY" before calling writeDB. "DB" file MUST exist or nothing is written.
Note: Existing content is overwritten.
usage: jssh_writeDB "ARRAY" "filename"
usage: jssh_writeDB_async "ARRAY" "filename"
example:
# Prepare array to store values
declare -A WRITEVALUES
WRITEVALUES["value1"]="example"
WRITEVALUES["value2"]="a value"
WRITEVALUES["whynot","subindex1"]="whynot A"
WRITEVALUES["whynot","subindex2"]="whynot B"
WRITEVALUES["whynot","subindex2","text"]="This is an example content for pseudo multidimensional bash array"
# create DB
jssh_newDB "${DATADIR:-.}/myvalues"
# write to file data-bot-bash/somevalues.jssh from array MYVALUES
jssh_writeDB "WRITEVALUES" "${DATADIR:-}/myvalues"
# show what's written
cat "${DATADIR:-}/myvalues.jssh"
["value1"] "example"
["value2"] "a value"
["whynot","subindex2","text"] "This is an example content for pseudo multidimensional bash array"
["whynot","subindex2"] "whynot B"
["whynot","subindex1"] "whynot A"
jssh_printDB
Print content of an ARRAY to STDOUT. ARRAY name must be declared with "declare -A ARRAY" before calling printDB..
usage: jssh_printDB "ARRAY"
example:
# Prepare array to store values
declare -A PRINTVALUES
# read file data-bot-bash/myvalues.jssh into array READVALUES
jssh_readDB "PRINTVALUES" "${DATADIR:-}/myvalues"
# print DB to stdout
jssh_printDB READVALUES
["value1"] "example"
["value2"] "a value"
["whynot","subindex2","text"] "This is an example content for pseudo multidimensional bash array"
["whynot","subindex2"] "whynot B"
["whynot","subindex1"] "whynot A"```
jssh_updateDB
Update/Add content of an ARRAY into a jsshDB file. ARRAY name must be declared with "declare -A ARRAY" before calling updateDB. "DB" file MUST exist or nothing is written.
Note: Existing content not in ARRAY is kept in file.
usage: jssh_updateDB "ARRAY" "filename"
usage: jssh_updateDB_async "ARRAY" "filename"
example:
# continued example from writeDB
MYVALUES=()
MYVALUES["newvalue"]="this is new"
# update file data-bot-bash/somevalues.jssh from array MYVALUES
jssh_updateDB "MYVALUES" "${DATADIR:-.}/myvalues"
# show what's written
["value1"] "value1"
["loveit"] "value2"
["whynot"] "value3"
["newvalue"] "this is new"
# now writeDB
cat "$DBfile"
jssh_writeDB "MYVALUES" "${DATADIR:-.}/myvalues"
# show what's written, ups!
cat "$DBfile"
["newvalue"] "this is new"
jssh_readDB
Read content of a file in JSON.sh format into given ARRAY. ARRAY name must be declared with "declare -A ARRAY" upfront,
usage: jssh_readDB "ARRAY" "filename"
usage: jssh_readDB_async "ARRAY" "filename"
Note: readDB uses concurrent / shared locking from flock so multiple processes can read from file, as long no process is writing. Maximum timeout for reading is 1s to not block readers.
example:
# Prepare array to read values
declare -A READVALUES
# read file data-bot-bash/myvalues.jssh into array READVALUES
jssh_readDB "READVALUES" "${DATADIR:-}/myvalues"
# sinple command to output values ONLY
printf "${READVALUES[*]}"
example a value This is an example content for pseudo multidimensional bash array whynot B whynot A
# print DB to stdout
jssh_printDB READVALUES
["value1"] "example"
["value2"] "a value"
["whynot","subindex2","text"] "This is an example content for pseudo multidimensional bash array"
["whynot","subindex2"] "whynot B"
["whynot","subindex1"] "whynot A"
# access Array
echo "${READVALUES[vaule2]}"
a value
# change / add values
READVALUES["value2"]="this is a changed value"
echo "${READVALUES[vaule2]}"
this is a changed value
READVALUES["value3"]="new value"
READVALUES[whynot,subindex3]="new subindex value"
# new output
jssh_printDB READVALUES
["value1"] "example"
["value3"] "new value"
["value2"] "this is a changed value"
["whynot","subindex2","text"] "This is an example content for pseudo multidimensional bash array"
["whynot","subindex3"] "new subindex value"
["whynot","subindex2"] "whynot B"
["whynot","subindex1"] "whynot A"
jssh_insertKeyDB
Insert, update, append a key=value pair to a jsshDB file, key name is only allowed to contain '-a-zA-Z0-9,._'
usage: jssh_insertKeyDB "key" "value" "filename"
usage: jssh_insertKeyDB_asnyc "key" "value" "filename"
deprecated: jssh_insertDB was renamed in version 0.96 to jssh_insertKeyDB
Note: inserKeytDB uses also excusive write locking, but with a maximum timeout of 2s. insertKeyDB is a "fast" operation, simply adding the value to the end of the file.
example:
jssh_insertKeyDB "newkey" "an other value" "${DATADIR:-.}/myvalues"
jssh_deleteKeyDB
Deleted a key=value pair from a jsshDB file, key name is only allowed to contain '-a-zA-Z0-9,._'
usage: jssh_deleteKeyDB "key" "filename"
usage: jssh_deleteKeyDB_async "key" "filename"
example:
jssh_deleteKeyDB "delkey"" "${DATADIR:-.}/myvalues"
jssh_countKeyDB
Increase a key=value pair from a jsshDB file by 1, key name is only allowed to contain '-a-zA-Z0-9,._' If value is given key is increased by value.
Side effect: if value is given key is updated "in place" (slower) and file is cleaned up, if no value is given fast path is used and new count is added to the end of file.
usage: jssh_countKeyDB "key" "filename" ["value"]
usage: jssh_countKeyDB_async "key" "filename" ["value"]
example:
jssh_countKeyDB "usercount"" "${DATADIR:-.}/myvalues"
