Measure execution time of command I just executed without interrupting it now

Question

Usually I measure execution times with

time updater

Unfortunately I already started the updater and do not want to interrupt it because this would cause other trouble.

How can I still see tomorrow when I return to work the time it needed to complete

Answer 1

Open a new terminal and execute date to get the current time. Type date and hit Enter in the terminal running updater. That will show you the time that updater finishes. Subtract the two.

Answer 2

appcheck.sh:

#!/bin/bash

PROGRAM1=updater
PPCHK=1

while [ "$PPCHK" -eq "1" ]
do
    PPCHK=$(ps aux | grep -v grep | grep -c $PROGRAM1)
    sleep 1;
done

And then time appcheck.sh
