Thank all now I am able to progress :
file1 i am able to extract the start and end timestamp
file 2 i am able to extract the timestamp
used the following
my $t1 = Time::Piece->strptime('Feb 23 01:10:28 2018', '%b %d %H:%M:%S
%Y'); coming from file1
my $t2 = Time::Piece->strptime('02/23/18 01:10:33', '%m/%d/%y %H:%M:%S');
coming from file2
my $t3 = Time::Piece->strptime('Feb 23 01:10:36 2018', '%b %d %H:%M:%S
%Y'); coming from file 1
if ($t2 > $t1 and $t2 < $t3) { ... } till here it working fine
now I would like to print all lines from file2 starting from t2 02/23/18
01:10:33 till very next timestamp which will be greater than t3 :
for example the file2 would look like this:
===========================================================================================================
LOG file opened at 02/23/18 01:10:33
ERR-05007: Warning: Intra source concurrency disabled because the
preprocessor option is being used.
Field Definitions for table OPATCH_XML_INV
eject rows with all null fields
Fields in Data Source:
ERR-04095:failed: Unable to create patchObject
Possible causes are:
"
LOG file opened at 04/26/18 06:10:33
===========================================================================================================
This logfile may have other time but i would to extract only the above
lines because messages occured between t1 and t3 after I extract these i
want to print the error lines for example ERR-05007
the issue I am facing if there are multiple error in the file it is
printing for each occurance of ERR-05007 instead it should print only the
error lines between t1 and t3 from file2
Please advice ,
thanks,
