Which is all very helpful, except the code provided on their website only allows plain text, you can’t pass $variables onto it Having started playing with Linux Bash scripts,…

Welcome to the forums @Bryce_Canion

Could you show us some code that you are trying to run so that we can further help you?

As the error implied, you sent an empty message over, which most probably indicates that the command you ran return empty or error

@doob187 thx for the quick code snippet example!

Try put this in front of your code

# ``` code here

and end it with ```

or select your code and then click on the " \</\> "

Ok, skipped a thing above.  
I get the date [test mesage] 13:56:49 Domenica 17-Maggio,2020 status done like this.  
the command I’m trying to send is $dk and should be processed by another bot in the channel.

By another bot… erm… I’m not understanding, anyway, let’s check your $dk

Can you confirm that it returns the output by

`echo $dk`

I have a bot on the discord channel who takes some $commands as inputs. I want to make a script to give him some commands in sequence basically. Problem is I’m not managing to feed him those commands through this process.

Where do I write echo $dk

PS thanks for help

Ahhhhhhh I get you now

So you want to output “$dk” to your channel as it is.

We took it that you have a variable called $dk in Linux itself, not discord.

In that case you would do this to your message content:

`your_text="white space and your '$dk' message"`

You need to wrap the $dk with **Single Quotes** (not Double-Quotes), to special-escape that whole string, which is $dk

So if you only want to output “$dk” to your channel

`my_msg='$dk'`  
or  
`my_msg="'$dk'"`

Have a try at it, @doob187 tested it and it worked 🙂

Let us know if it worked out 😁

OK thanks, using only single quotes (I did not use the `my_msg=`…, is it a problem?) I can have it. Unluckily seems like the other bot doesn’t recognize it, probably because it comes from another bot. Thanks for help though  
Don’t want to bother you more, by chance do you know if I can send messages this way as user and not as bot?
