Shell Programming and Scripting

Hi

I have a big log file

:08,936 DEBUG [SoapUIMultiThreadedHttpConnectionManager] HttpConnectionManager.getConnection: config =

11:39:09,335 DEBUG [SoapUIMultiThreadedHttpConnectionManager] Notifying no-one, there are no waiting threads


I want to grep the first occurrence of string "Notifying no-one, there are no waiting threads" and last occurrence and calculate the count of which this string has appeared .And calculate time diffrence.

For eg
First occurrence
11:39:09,335 DEBUG [SoapUIMultiThreadedHttpConnectionManager] Notifying no-one, there are no waiting threads

last occurrence
12:33:09,335 DEBUG [SoapUIMultiThreadedHttpConnectionManager] Notifying no-one, there are no waiting threads

Time difference is 12:33:09-11:39:09 between first occurrence and last occurrence and also count number of occurrences.


Input should be a file name
Out put must be count divided by (time diff is seconds) so that i can check number of occurrences per sec

to grep the spezific line use

Code:

Code:

grep -i 'Notifying no-one, there are no waiting threads' file.txt

i don't howto calculate the time between the firt and last post
sorry

Thank you .

I want to grep first occurrence of string and note down the time for it.Grep last occurrence of string and note down time .!!!!!!

ok here the way:

FIRSTONE=`grep -i 'Notifying no-one, there are no waiting threads' log_file.txt | head -n1 | awk '{ print $1}'`

LASTONE=grep -i 'Notifying no-one, there are no waiting threads' log_file.txt | tail -n1 | awk '{ print $1}'

Now we have two dates

If you are on Linux convert these dates to UTC time..

FIRSTONE=`date --date="$FIRSTONE" +%s`
LASTONE=`date --date="$LASTONE" +%s`

Now subtract LASTONE from FIRST ONE ... and you get secs ...

Let me know if you need complete script..

Hi

Try this,

Code:

#!/bin/sh

filename=$1;

grep -i "Notifying no-one, there are no waiting threads" $filename > temp.txt

occur=`cat temp.txt | wc -l`
echo "Occurances in the file : - $occur"

time_first=`head -1 temp.txt | awk -F "," '{print $1}'`
time_last=`tail -1 temp.txt | awk -F "," '{print $1}'` 

first_sec=`date --date="$time_first" +%s`
last_sec=`date --date="$time_last" +%s`

diff=`expr $last_sec - $first_sec`
echo "Time diff $diff seconds"
rm temp.txt
