[WTFPLv2](http://www.wtfpl.net/txt/copying/).
Uses JSON.sh and the magic of sed.
Bashbot is written in bash. It depends on commands typically available in a Linux/Unix
Environment. For more concrete information on the common commands provided by recent
versions of coreutils, busybox or toybox, see Developer_Notes.
Note for MacOS and BSD Users: Bashbot will not run without installing additional software
as it uses modern bash and (gnu) grep/sed features. See Install_Bashbot.
Note for embedded systems: You need to install a "real" bash as the vanilla installation
of busybox or toybox is not sufficient. See Install_Bashbot.

Security Considerations
## Security Considerations
Running a Telegram Bot means it is connected to the public and you never know
what's send to your Bot.
Running a Telegram Bot means it is connected to the public and you never know what's send
to your Bot.
Bash scripts in general are not designed to be bulletproof, so consider this Bot as a
proof of concept. Bash programmers often struggle with 'quoting hell' and globbing, see
Implications_of_wrong_quoting.
Whenever you are processing input from untrusted sources (messages, files, network) you
must be as careful as possible (e.g. set IFS appropriately, disable globbing with set -
f and quote everything). In addition remove unused scripts and examples from your Bot
(e.g. everything in example/) and disable/remove all unused bot commands.
It's important to escape or remove $ in input from user, files or network (as bashbot
does). One of the powerful features of Unix shells is variable and command substitution
using ${} and$() can lead to remote code execution (RCE) or remote information disclosure
(RID) bugs if unescaped $ is included in untrusted input (e.g. $$ or $(rm -rf /*)).
A powerful tool to improve your scripts is shellcheck. You can use_it_online or install
shellcheck_locally. Shellcheck is used extensively in bashbot development to ensure a high
code quality (e.g. it's not allowed to push changes without passing all shellcheck tests).
In addition bashbot has a test_suite to check if important functionality is working as
expected.
Bash scripts in general are not designed to be bulletproof, so consider this
Bot as a proof of concept.
Bash programmers often struggle with 'quoting hell' and globbing,
see [Implications of wrong
quoting](https://unix.stackexchange.com/questions/171346/security-implications-o
f-forgetting-to-quote-a-variable-in-bash-posix-shells).
Use printf whenever possible
Whenever you are processing input from untrusted sources (messages, files,
network) you must be as careful as possible
(e.g. set IFS appropriately, disable globbing with `set -f` and quote
everything). In addition remove unused scripts and examples
from your Bot (e.g. everything in `example/`) and disable/remove all unused bot
commands.
If you're writing a script that accepts external input (e.g. from the user as arguments or
the file system), you shouldn't use echo to display it. Use_printf_whenever_possible.
It's important to escape or remove `$` in input from user, files or network
(_as bashbot does_).
One of the powerful features of Unix shells is variable and command
substitution using `${}` and`$()` can lead to remote code execution (RCE) or
remote information disclosure (RID) bugs if unescaped `$` is included in
untrusted input (e.g. `$$` or `$(rm -rf /*)`).
Run your Bot as a restricted user
A powerful tool to improve your scripts is `shellcheck`. You can [use it
online](https://www.shellcheck.net/) or
[install shellcheck
locally](https://github.com/koalaman/shellcheck#installing). Shellcheck is used
extensively in bashbot development
to ensure a high code quality (e.g. it's not allowed to push changes without
passing all shellcheck tests).
In addition bashbot has a [test suite](doc/7_develop.md) to check if important
functionality is working as expected.
I recommend running your bot as a user with almost no access rights. All files your Bot
has write access to are in danger of being overwritten/deleted if your bot is hacked. For
the same reason every file your Bot can read is in danger of being disclosed. Restrict
your Bots access rights to the absolute minimum.
Never run your Bot as root, this is the most dangerous you can do! Usually the user
'nobody' has almost no rights on Linux/Unix systems. See Expert_use on how to run your Bot
as an other user.
### Use printf whenever possible
Secure your Bot installation
If you're writing a script that accepts external input (e.g. from the user as
arguments or the file system),
you shouldn't use echo to display it. [Use printf whenever
possible](https://unix.stackexchange.com/a/6581).
Your Bot configuration must not be readable by other users. Everyone who can read your
Bots token is able to act as your Bot and has access to all chats the Bot is in!
Everyone with read access to your Bot files can extract your Bots data. Especially your
Bot config inconfig.jssh must be protected against other users. No one except you should
have write access to the Bot files. The Bot should be restricted to have write access
tocount.jssh and data-bot-bash only, all other files must be write protected.
To set access rights for your bashbot installation to a reasonable default runsudo ./
bashbot.sh init after every update or change to your installation directory.

## FAQ
### Is this Bot insecure?
Bashbot is not more (in)secure than a Bot written in another language. We have
done our best to make it as secure as possible. But YOU are responsible for the
bot commands you wrote and you should know about the risks ...
**Note:** Up to version 0.941 (mai/22/2020) telegram-bot-bash had a remote code
execution bug, please update if you use an older version!
### Why Bash and not the much better xyz?
Well, that's a damn good question... maybe because I'm a Unix admin from the
stone age. Nevertheless there are more reasons from my side:
- bashbot will run wherever bash and (gnu) sed is available, from embedded
Linux to mainframe
- easy to integrate with other shell scripts, e.g. for sending system message /
health status
- no need to install or learn a new programming language, library or framework
- no database, not event driven, not object oriented ...
### Can I have the single bashbot.sh file back?
At the beginning bashbot was simply the file`bashbot.sh` that you could copy
everywhere and run the bot. Now we have 'commands.sh', 'mycommands.sh',
'modules/*.sh' and much more.
Hey no problem, if you are finished with your cool bot,
run`dev/make-standalone.sh` to create a stripped down version of your bot
containing only
'bashbot.sh' and 'commands.sh'! For more information see [Create a stripped
down version of your Bot](doc/7_develop.md).
### Can I send messages from CLI and scripts?
Of course you can send messages from command line and scripts! Simply install
bashbot as [described here](#Your-really-first-bashbot-in-a-nutshell),
send the message '/start' to set yourself as botadmin and then stop the bot
with `./bashbot.sh stop`.
Bashbot provides some ready to use scripts for sending messages from command
line in `bin/` dir, e.g. `send_message.sh`.
```bash
bin/send_message.sh BOTADMIN "This is my first message send from CLI"
bin/send_message.sh --help
```
You can also source bashbot for use in your scripts, for more information see
[Expert Use](doc/4_expert.md).
FAQ
### Blocked by telegram?
This may happen if too many or wrong requests are sent to api.telegram.org,
e.g. using a invalid token or invalid API calls.
If the block stay for longer time you can ask telegram service to unblock your
IP-Address.

bin/send_message.sh BOTADMIN &quot;This is my first message send from CLI&quot;
bin/send_message.sh --help
You can also source bashbot for use in your scripts, for more information see Expert_Use.
Blocked by telegram?
This may happen if too many or wrong requests are sent to api.telegram.org, e.g. using a
invalid token or invalid API calls. If the block stay for longer time you can ask telegram
service to unblock your IP-Address.
You can check with curl or wget if you are blocked by Telegram:
```bash
curl -m 10 https://api.telegram.org/bot
#curl: (28) Connection timed out after 10001 milliseconds
wget -t 1 -T 10 https://api.telegram.org/bot
#Connecting to api.telegram.org (api.telegram.org)|46.38.243.234|:443...
failed: Connection timed out.
curl -m 10 https://api.telegram.org/bot
#curl: (28) Connection timed out after 10001 milliseconds
nc -w 2 api.telegram.org 443 || echo "your IP seems blocked by telegram"
#your IP seems blocked by telegram
```
wget -t 1 -T 10 https://api.telegram.org/bot
#Connecting to api.telegram.org (api.telegram.org)|46.38.243.234|:443... failed:
Connection timed out.
Bashbot offers the option to recover from broken connections (blocked).
Therefore you can provide a function
named `bashbotBlockRecover()` in `mycommands.sh`, the function is called every
time when a broken connection is detected.
Possible actions are: Check if network is working, change IP-Address or simply
wait some time.
See `mycommnds.sh.dist` for an example.
