some thing like this :

Code:
#!/bin/bash
genexpression()
{
stime=`date '+ %H'`
stime=`expr $stime \- 5`
if (( $stime < 10 ))
then
stime=0${stime}
fi
export express=`date '+%m/%d/%Y'`\ $stime
}
genexpression

echo $express

t=`grep -w "$express" log.txt | wc -l`

if [ $t -ne 0 ];then
echo "suces"
else
echo "fail"
fi
