in thread Find Execution time of perl script??

No need to calculate start time: it is always available through $^T (see perlvar).

print time - $^T;
And for programs with so few liners, there is probably little need for use strict, use warnings, meaningful variable names, etc,. ( Some posters seem too vocal on such matters; with a little more encouragement, they might also advise on the java-way of doing things.)

    True that warnings, strict, etc. may not be entirely necessary for programs that are only a half-dozen lines long, but:
    1. It's good to display them in sample code which new initiates may emulate
    2. You never know when your basic 6-line program may start evolving into something more substantial
    3. For some of us, -wT and use strict are such habits that it's more work to exclude them than to include them
      Too true.

      In fact, I use a vim file that looks like so:

      ~ cat #!/usr/bin/perl -w use strict; use Data::Dumper::Simple;

      So yes, in my case at least - it is actually more trouble for me to not use strict and warnings :)

[vedagiri89]: how do fix this issue
[choroba]: This usually happens when you have more than one version of Perl, and you mix the libraries
[hippo]: Which O/S?
[vedagiri89]: i have searched many forum...not getting resolutions
[vedagiri89]: centos
[Corion]: vedagiri89: Either what choroba said, or maybe you misspelled some module name (on Windows), like use Strict; or something like that.
[vedagiri89]: @choroba, what to do for that
[Corion]: Ah, you are not on Windows, so disregard my opinion.
[vedagiri89]: in centos, how to fix this.
