jesuashok has asked for the wisdom of the Perl Monks concerning the following question:

Dear monks,

I have done a super search before posting this node. I did not find anything related to this.

I am going ahead with that hope.

Today I saw a perl script which contains the first line as

#!/usr/bin/env perl
when I did a super search, I find lot of scripts which contains these lines, But I did not get any explanation on this.

I am familiar with the following interpolation :-
My questions are :-
1) How the interpolation happens when I give #!/usr/bin/env perl.
2) which one is faster either #!/usr/bin/perl or #!/usr/bin/env perl.

Thanks a lot. :-)
