the
date command. I'd like to know if there's a way to get a resolution
you can start with 'date +%s'
the tic() toc() approach is nice, here is what
we do to measure exact time between 2 events:
read t1 trash /proc/uptime
/proc/uptime is much simplier :-)

and it's even monotonic...and...fast.
(date +%s can jump into future and past)
read t1 trash /proc/uptime
do_something()
read t2 trash /proc/uptime

Hi,
I'm using TP-Link WR741ND routers with openwrt, and I want to log some
debug files, to know for example how many packets have been transmitted
in a period of time. For that purpose I use while loops and log the
results. The problem is that I couldn't find how to use a good time
reference
Just (ab)use any other time function like time
tic() { TICFILE=$(mktemp); rm $TICFILE; mkfifo $TICFILE; ((TIME=$(time
cat $TICFILE 21 | sed -rne '/real/{s/^real[[:blank:]]*//;p}'); echo
$TIME$TICFILE ) )2/dev/null; }
toc() { echo -n $TICFILE; awk BEGIN { print $(cat $TICFILE | sed -e
's/m/ * 60
