checking time stamp - UNIX for Dummies Questions & Answers

Manvar Khan · #1 08-22-2007

Hi,
I am having a script in which I am again calling a script, but before calling that script I need to perform a time check (say 1 - 2 am i.e. I would be able to call that script if time is between 1:00 am and 2:00 am) but this time stamp needs to be configurable.
can anybody suggest me how I can achive this..

Thanks in advance

You can do something like this--

#!/bin/ksh
echo "To run a script in between a given time"
str1=`date | cut -d" " -f4`
str2=`echo $str1 | cut -d":" -f1`
if [[ $str2 -eq 13 ]] or if [[ $(date +%h) -eq 13 ]]
then
ksh test2
else
echo "Wrong"
fi

Thanks

Without so many 'cut's

Code:

#! /bin/ksh

if [[ $(date +%H) -eq 01 ]] ; then
  echo "Judgement day has arrived"   # run the script
else
  echo "Judgement day has not arrived"
fi

thanks Namish for your reply,
but this is not the solution I want, as per your solution

if [[ $str2 -eq 13 ]]

now in future if I want to change 13 to 15 then I have make changes in the code.
and I dont want to cahnge in the code.
I want my script capable of taking this time from some where outside this script.
I hope you got my problem.

Regards
Manvar

Code:

#! /bin/ksh
#
#

case $# in
    2) start=$1; end=$2 ;;
    *) echo "Need a start and end time"; exit 1;;
esac

now=$(date +%H)
if [[ $now -ge $start && $now -lt $end ]] ;
then
    echo "Judgement Day has arrived."
else
    echo "Judgement Dat yet to arrive."
fi;

thanks vino,
I am sorry I forgot to tell that we cannot use command line aurguments here (It is the requirement).

Manvar,
You can read the time like this

echo "Enter the start time stamp"
read stime

echo "Enter the end time"
read etime

and do your manipulations on these variables itself.
is that going to help you.

Thanks
Namish
