Description John Hardin 2020-11-24 16:20:27 UTC

I have a handful of Gentoo boxes that I maintain, and I regularly find myself running emerges on some or all of them via ssh at the same time (e.g. for weekly updates) in a tabbed gnome-terminal window.

It gets a bit confusing because all of the sessions' titles look much the same.

It would be nice if the terminal window title text displayed while emerge was running included the hostname - for example, instead of:

  Jobs: 20 of 21 complete, 1 running Load avg: 5.98, 6.65, 6.74

it was:

  Jobs@athena: 20 of 21 complete, 1 running Load avg: 5.98, 6.65, 6.74

...where "athena" is the hostname.

This could potentially be put behind a command-line option vs. being default behavior.

Potential simple fix attached.

Reproducible: Always

Steps to Reproduce:
1. Open sessions to three different Gentoo boxes in a tabbed terminal window
2. Merge lots of stuff on all three boxes simultaneously
3. Look at the tab labels in the terminal window - which machine is which?

I was just informed of the existing $HOSTNAME behavior. That's sufficient, but it should be documented on the emerge man page...
