linux service script for storing uptime
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

Can you please advise a script for the following:

write linux service named system_up_duration .This service will create one file named uptime in directory ‘/temp/’. In this file the service will store the total time for which the system is up and running .The file will be updated after every one minute. If system is rebooted the time inside the file uptime should be reset to 0




2. Relevant commands, code, scripts, algorithms:



3. The attempts at a solution (include all code and scripts):


With my limited knowledge, I feel the script ( say xyz.some_ext) should be like this:


#!/bin/bash
DIR=/temp

if [ ! -d "$DIR" ]
then

mkdir /temp/
uptime | awk {'print $3,$4}' | cut -d, -f1 > /temp/uptime

else

echo > /temp/uptime
uptime | awk {'print $3,$4}' | cut -d, -f1 > /temp/uptime





Then we can set this script to run once from rc.local during startup. However I do not know how to run this as service ( else we will have to run a cron to update time every min).

Please advise.


Thank you

uptime

UPTIME(1)							   User Commands							 UPTIME(1)

NAME

       uptime - Tell how long the system has been running.

SYNOPSIS

       uptime [options]

DESCRIPTION

       uptime  gives  a one line display of the following information.	The current time, how long the system has been running, how many users are
       currently logged on, and the system load averages for the past 1, 5, and 15 minutes.

       This is the same information contained in the header line displayed by w(1).

       System load averages is the average number of processes that are either in a runnable or uninterruptable state.	A process  in  a  runnable
       state is either using the CPU or waiting to use the CPU.  A process in uninterruptable state is waiting for some I/O access, eg waiting for
       disk.  The averages are taken over the three time intervals.  Load averages are not normalized for the number of CPUs in  a  system,  so  a
       load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.

OPTIONS

       -p, --pretty
	      show uptime in pretty format

       -h, --help
	      display this help text

       -s, --since
	      system up since, in yyyy-mm-dd HH:MM:SS format

       -V, --version
	      display version information and exit

FILES

       /var/run/utmp
	      information about who is currently logged on

       /proc  process information
