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

[download]
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 :- 
#!/usr/bin/perl

[download]
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. :-)
