That question was interesting. I don't know Hexagony, so I wonder what does /$/ctrick does in it?
Especially # since it marks a comment in many many languages.
@DigitalTrauma Welcome to the chat room! Dennis added sed recently to TIO, and if I remember well my last conversation with him, he plans to add bash and most likely dc as well in the next version of TIO.

This is more of an ask now, get reply later kind of room and you are always welcome. Maybe you can find useful the automated answer feeds in bash, sed and dc languages.
@seshoumara Hexagony is a 2D language. The / redirects the instruction pointer up and to the left. It's the same priciple that I used here: codegolf.stackexchange.com/a/97562/57100
I don't really know the language. All I know is that letters put their ASCII value in memory, ';' outputs the character that corresponds to the value in memory, and the mirrors reflect the instruction pointer.
Are you working on something cool while you're gone?
@Dennis I was playing with sed.tryitonline.net - I assume you know the e eval qualifier to sed's s/// command - this allows running of somewhat arbitrary code on the server. I don't know how well you have all this sandboxed, etc - I just wanted to draw this potential security backdoor to your attention

@DigitalTrauma The e command and the e flag for the s command were the initial reasons why Dennis didn't want to implement sed to TIO until v2. But he said he found a way, so yes, he definitely knows. Version 2 he said we'll have an even better sandbox.
That's why he didn't added bash yet.
The r,R,w and W commands are also a possible security issue, haven't tried those.

The first line prints trick if there is an empty string at the end of input. (sed doesn't do anything if there isn't input, but a blank line on stdin is allowed in this case)
