Script to read log file
Hi,

Im looking for a shell script which will search for a particular string in a log file as below scenario

1. I need to run URL http://localhost/client/update?feedid=200 in shell script at(eg)4:00 PM which will not take more than 15 mins to complete.

2. After 15 mins i need to check the log from 4:00 PM to 4:15 PM.

3. Need to check logs file for 2 strings (a) Feed id=200 (b) Item=Product example, if these 2 string matches i need to check for "Error" string.

4. If 3 string matches i will send a mail stating "Failed"

5. If string "Error" is not found in last 15 mins log(only string a & b should match) then i will execute another 6 URLS and atlast will trigger mail stating "Success"

6. Is this above sequence possible in shell script? Please guide me and my script is below - Im really stuck in comparing string and checking last 15 mins log.

7. Log with Error
Code:
[INFO 12-03-01:04:10:25] Starting FeedRunner for feed: 200  Product example Items 
[INFO 12-03-01:04:12:40] Error FeedRunner for feed: 200 Product example Items
[INFO 12-03-01:04:20:25] Stopping FeedRunner for feed : 200  Product example Items Feed time taken 231743

8. Log without Error
Code:
[INFO 12-03-01:04:10:25] Starting FeedRunner for feed: 200  Product example Items 
[INFO 12-03-01:04:20:25] Stopping FeedRunner for feed : 200  Product example Items Feed time taken 2743

9. Script
Code:
#!/bin/sh

START=$(date +"%y-%m-%d:%T")
echo $START
curl "http://localhost/mcfeeds/runfeed?feedid=200"
END=$(date "%y-%m-%d:%T")
echo $END

cat /path/logfile.log | sed -n '/$START/,/$END/ p' > output.txt

grep '200'&'Product example'&'Error' output.txt

Thanks

hosts

HOSTS(5)							File Formats Manual							  HOSTS(5)

NAME

       hosts - hostname to IP address database

SYNOPSIS

       /etc/hosts

DESCRIPTION

       The  hosts  database  lists the IP addresses and the hostnames that translate to these IP addresses.  It is used by nonamed(8) in a network
       without name servers.  A simple /etc/hosts may look like this:

	      127.0.0.1      localhost
	      192.9.200.1    darask
	      192.9.200.2    burask

       The localhost entry lists a special address that refers to the local host itself (a kind of /dev/tty for hosts.)  You should only  list	it
       if nonamed needs it!  The other entries are actual machines.  The file may contain comments marked with '#'.

       You  can  have  aliases	(more  hostnames on the same line), but it is not recommended, because nonamed can't present them to the system as
       CNAME records.  An often seen form like

	      192.9.200.1    darask.home.cs.vu.nl  darask

       is harmless though, and has the small advantage that you can use the short name in /etc/ethers so rarpd can match it at boot time.

FILES

       /etc/hosts     Hosts database.

SEE ALSO

       ethers(5), nonamed(8), rarpd(8), boot(8).
