everyone

here is my script

/bin/wstalist | grep 'uptime'

Which is return value like "uptime": 3456, yes there's a , coming with output.

These number are seconds. I want to convert it to hh:mm:ss format. and want it to be simple cause it will running by a router(busybox) in every minute.

So the problem is I don't know how.

Can someone help me? please.

line=$(/bin/wstalist | grep 'uptime')
sec=$line##* 
sec=$sec%%,
h=$(( $sec / 3600 ))
m=$(( $(($sec - $h * 3600)) / 60 ))
s=$(($sec - $h * 3600 - $m * 60))
if [ $h -le 9 ];then h=0$h;fi
if [ $m -le 9 ];then m=0$m;fi
if [ $s -le 9 ];then s=0$s;fi
echo $h:$m:$s

#!/bin/bash

# Here's the output from your command
output='"uptime": 3456,'

# Trim off the interesting bit
seconds="$(echo "$output" | awk ' print $2 ' | sed -e 's/,.*//')"

readonly SECONDS_PER_HOUR=3600
readonly SECONDS_PER_MINUTE=60

hours=$(($seconds / $SECONDS_PER_HOUR))
seconds=$(($seconds % $SECONDS_PER_HOUR))
minutes=$(($seconds / $SECONDS_PER_MINUTE))
seconds=$(($seconds % $SECONDS_PER_MINUTE))

printf "%02d:%02d:%02dn" $hours $minutes $seconds
