OK, I've got the picard.jar file in my directory but I cannot get the chmod +x Picard to work? My goal is to run Picard as though it is an executable program. Here are my series of commands, I'll ** where I start having issues:

$ mkdir picard
$ cd picard
$ wget https://github.com/broadinstitute/picard/releases/download/2.8.1/picard.jar
$ java –jar /software/picard/picard.jar
#!/bin/bash
java -jar /software/picard/picard.jar $*
**$ chmod +x Picard

Hear is the error message;

$chmod +x Picard
chmod: cannot access 'Picard': No such file or directory

my next step would have been:

$sudo ln -s /software/picard/Picard /usr/local/bin

Again thinking I could run Picard as though it were an executable program:

$Picard

Is there a better way to simply make Picard an executable?
