Hi, I have logs files like this

<Oct 7, 2008 7:43:59 AM CDT> <Notice> <Security> <BEA-090082> <Security initializing using security realm myrealm.>
2008-10-07 07:44:14,106 INFO [org.springframework.core.CollectionFactory] - <JDK 1.4+ collections available>

I need to search all the lines for a particular date and then copy them to a different file. For example if I mention Oct 7, 2008 as input the above two lines are to be copied into a new file named  date_file.txt

Thanks in advance,

Where does the sort come into the question?

To search for a date, you just need to do

egrep "2008-10-07|Oct 7, 2008" log >date_file.txt

The date in the logs will be in either of the below two formats:
<Oct 7, 2008>
 2008-10-07
We need to search for these two formats depending on the date we get as input and then copy the lines containing these lines to a different file.....

What format will the date be entered as?  Is this on Solaris 10?

Its solaris 9. We can ask the user to enter the date in any particular format.

One last question, are you allowed to install any additional software?  If you can install GNU date, it would make this task much more simple.

I really wish we could but we are not allowed to install software.

OK, here's a script which will accept input in YYYY-MM-DD format
#!/bin/sh

DATE1=$1

year=`echo $DATE1 | cut -f1 -d-`

mon=`echo $DATE1 | cut -f2 -d-`

day=`echo $DATE1 | cut -f3 -d- | sed "s/^0//"`
 

case $mon in

1)  mon=Jan ;;

2)  mon=Feb ;;

3)  mon=Mar ;;

4)  mon=Apr ;;

5)  mon=May ;;

6)  mon=Jun ;;

7)  mon=Jul ;;

8)  mon=Aug ;;

9)  mon=Sep ;;

10) mon=Oct ;;

11) mon=Nov ;;

12) mon=Dec ;;

esac
 

DATE2="$mon $day, $year"

egrep "$DATE1|$DATE2" /some/log >date_file.txt
