Question

In bash, is there a way to echo/print the last stdout? Is there a variable that stdout is assigned to?

I don’t want to redirect the output. I just want to be able to read/print it after a command is run.

Answer 1

Nope, there’s no way to see a line sent to stdout unless stdout‘s already been sent somewhere. If it was sent to a console, copy the text from that console. If you sent it to a file, tail -n 1 that file. If you can re-run the command which generates the line you want to see, I would suggest piping it to tail -n 1 to see just the last line of output.

Bash keeps a history of executed commands (~/.bash_history by default in GNU Bash 4.2), but not of output.
