I have the following function set up as a bash alias:

newpl () 
{ 
    [[ -z $1 ]] && { 
        echo "usage:  newpl FILENAME"
        return
    }
    [[ -d $1 ]] || [[ ! -e $1 ]] && vim $1;
    [[ -e $1 ]] && { 
        chmod 0755 $1
        /bin/ls -al $1
    } || { 
        echo "File $1 was not saved"
    }
}

..and these 2 lines in my .vimrc:

ab bbb #!/bin/bash
ab ppp #!/usr/bin/perl ^M^Muse strict;^Muse warnings;^M^M
[download]

(those ^M are made inside of vim with CTRL-v, CTRL-m)

So on the command line just do newpl newfilename
And when vim starts, <i> ppp <enter>
Not as comprehensive as some of the other examples here but "works" :)
