Timing processes

[Robie Lutsey]

Hello again.

I want to time how long a "Tar" operation takes. Is there an easy method to do this?

Thanks!

yup - use timex(1)

Hello!

Just prepend "time" to the command you want to time.

So, instead of tar whatever...

you use

time tar whatever

and it will show you some time figures at the end (elapsed time, system time and user time)

If you are running say a backup job with tar over night, you could just write your output to a logfile something like this:

logfile=/tmp/tar.log
if [ -f $logfile ];
then
rm $logfile
touch $logfile
else
touch $logfile
fi

echo "Begin TAR backup command at " `date` >>$logfile 2>&1

tar cf >>$logfile 2>&1

echo "TAR backup command complete at " `date` >>$logfile 2>&1
