Q on Linux: Can't use arrow keys

[scholzi]

I recently installed Q/Kdb+ 4.0 onto PopOS and for some reason, I can't use the arrow keys to go back through my Q terminal history

When I press the up or down arrow I get an output similar to this

q)^[[A //up-arrow
q)^[[B //down-arrow

The above characters are outputted instead of going through the Q command history.

Does anyone know if there is a way to fix this

Thanks. Missed that because I used the Github docs for install

You'll need to install a utility program like rlwrap and run that when you start q to add command history navigation within your q session.
