Hello jayu_rao,

When comparing strings using eq, the match has to be exact to succeed. For the data line:

----- Sun Mar 8 10:51:20 2015::4426::Launching the JVM with following 
+options.

your regex is capturing $2 as "8" (a single character, no initial space). So when you come to compare it:

if ( $2 eq " 8") { $start_date= "08";}

the match fails. Two useful references:

But please follow choroba’s advice and use a hash lookup instead of a regex for this kind of conversion. Remember the Perl motto: when in doubt, use a hash! :-)

Hope that helps,
