Useful bash functions II

Most perl scripts I write start like this:

#!/usr/bin/perl
use strict;
use warnings;
#maybe the GPL or some other stuff...

Additionally it's always required to set the "x flag" via chmod - all in all quite annoying.
That's why I added the function shown below to my ~/.bashrc

np() {
        gplfile=~/Dokumente/gpl.txt
        if [ $# -eq 0 ]
        then 
                echo "filename required..."     
                return  
        fi
        if [ -e "$1" ] 
        then
                echo "file already exists!"
                return
        fi
        touch "$1" || { echo "can't touch $1" ; return ; }
        echo "#!/usr/bin/perl" >> "$1"
        if [ "$2" = "gpl" ] && [ -e "$gplfile" ]
        then
                cat "$gplfile" >> "$1"
        fi
        echo "" >> "$1"
        echo "use strict;" >> "$1"
        echo "use warnings;" >> "$1"
        echo "use 5.10.0;" >> "$1"
        echo "use feature 'say';" >> "$1"
        echo "" >> "$1"
        chmod 700 "$1"
        [ $EDITOR ] || EDITOR=vim
        $EDITOR "$1"
}

Usage: np filename [gpl]
