Ok here's the situation I have a log like the following:

(S0) Time: 124937.326033 - SendingTime: '20041108-12:49:29'
(S0) Time: 124937.389946 - SendingTime: '20041108-12:49:29'
(S0) Time: 124937.462494 - SendingTime: '20041108-12:49:29'
(S0) Time: 124937.551056 - SendingTime: '20041108-12:49:29'
(S0) Time: 124937.617128 - SendingTime: '20041108-12:49:29'
(S0) Time: 124937.689085 - SendingTime: '20041108-12:49:29'


I can have a few thousand lines like this in a log. How can I grep according to the time using the the numbers after "Time:" or after the date. Like if I want to grep out everything between 10:30 to 1:30

Any info you can spare would be much appreciated ..

thanks in advance

Try the following ... pass lowervalue and upper value as command line args.

script 12 14 will give times between 12:30 and 14:30
file1 is the file having data.

code:
-----------------------------------------

lowerlimit=$13000
upperlimit=$23000

while read line
do
patt=`echo $line | cut -d" " -f 3 | cut -d"\." -f 1`


if test $patt -ge $lowerlimit -a $patt -le $upperlimit
then
echo $line ;
fi

done < file1
