emergency exit to get output?

[marcelo321]

This is a weird reccomendation but what about a emergency exit to get output before getting runtime error?

Let's say we run a command that is important and we want to get the output, if it gets runtime error we can't see anything from the commands we just run.

It would be cool that if it keeps track of the runtime, a few seconds before getting to the error it saves the output from the command we just run.
