If then logic with TIME

Shell Programming and Scripting

Hi all,

Can anyone suggest how to formulate the if/then when TIME equals a certain time, in this case 23:55:00

export TIME=`date +%T`

function tnsrec {
if $TIME = 23:55:00; then
otherfunction
else exit
fi
}

Thanks in advance.

export TIME=`date +%T`

function tnsrec {
if [ $TIME = "23:55:00" ]
then
    #otherfunction
else
    exit
fi
}

Note that if you're off by one second, it won't work...

Hmm yes, good point.

How do I introduce a 'BETWEEN' condition?
ie something like

export TIME=`date +%T`  
function tnsrec 
{ if [ $TIME >= "23:55:00" OR $TIME < "23:55:59"] 
then     
#otherfunction 
else  exit 
fi 
}

Any ideas?

You could try stripping the colons and using it as an integer with -eq -gt -ge etc.

export TIME=$(date +"%H%M")
function tnsrec
{ if [ $TIME -eq 2355 ]
    then   #otherfunction  
    else   exit
  fi
}

Thanks for your reply.

I think I need to be able to check if TIME is between two DATEs.

that was I dont have to be sp specific about the TIME which could be a problem if you are out by 1 second or so.

So I believe I need a command to check a between condition.
