I like to watch portage from time to time, and wish emerge -j<number> had more detailed output. The following script, in another terminal, gives me just that.

Code:
#!/bin/bash
cd /vat/tmp/portage
trap 'kill $(pgrep -P $LOGVIEW) $LOGVIEW;exit' SIGINT

while true
do
        CURRENT_LOG=$(ls -dut */* | head -1 | sed 's/^.*\t//')/temp/build.log
        # Set xterm title
        echo -ne "\033]0;$CURRENT_LOG\007"
        (for try in $(seq 10)
        do
                tail -f $CURRENT_LOG
                sleep 1
        done) & LOGVIEW="$!"
        while [[ "$CURRENT_LOG" = "$(du -sk */* | sort -n | tail -1 | sed 's/^.*\t//')/temp/build.log" ]]
        do
                sleep 1
        done
        kill $(pgrep -P $LOGVIEW) $LOGVIEW
done

Hehe indeed it's very relaxing. Cheers for this one, went immediately into use.

Just one thing: In your script, it says cd /vat/tmp/portage

Glad to see this script. I had almost considered disabling multiple jobs on my system just so I could watch emerge progress.. On the other hand I like the cleanliness out the output when it is enabled. :P

The script seems to work well, but I'm getting a constant error as it runs.

Code:

/usr/local/bin/watch_emerge: line 16: 22743 Terminated              ( for try in $(seq 10);
do
    tail -f $CURRENT_LOG; sleep 1;
done )


That seems to come up every 10 or so lines and results in a constant barrage of output from emerge repeating itself as new lines are printed.

Although, --quiet-build n should work now.
