Cute, clever. There may be edge cases it doesn’t get right (parallel downloads/copies) but pretty useful when you’ve launched a job and didn’t think ahead of time to ask for progress.

I’ve used a signal handler (SIGHUP aka control-c) before as a “show progress” mechanism that I found very useful to monitor long running processes that were compute not io related (launched in screen fwiw to stay the active process).

Very cute and very clever. I think this could be extended with a watcher/main loop of its own, and keep a bit of context to spot any long transfers (say longer than 5s), and display a system-wide summary of all large transfer going on.

These use USR1 signal to show progress. HUP is kind of a weird choice since usually the intent of ^c is to end the program.

Yep I know. It was easier to do in the same window with the program in the foreground vs opening another window to send the kill -HUP to this one. Double control-c still killed the process.
