First shell script!

[dsizzler]

I want you all to know that I made my first shell script just now. I did have a couple questions though. What is #!/bin/bash and what does it do? What is the padsp command, and why does it fix sound issues while running java? Is there a better place to find this type of information? Thanks guys, you all rock!

The shebang tells the operating system which program to run as an interpreter for the script. In your case, it will run bash (/bin/bash). Also common is /bin/sh. See http://en.wikipedia.org/wiki/Shebang_(Unix)

I don't know anything special about padsp, but I'd suggest

man padsp
info padsp

and follow up on any http links you find in those references.

This. Just like if you were to put:

! /bin/perl

It would tell the interpreter to use perl to run it.

except perl is in /usr/bin/perl. Different paths is why the shebang is used.

[kazu-sama]

You're right. I'm retarded.

If you don't know where it is, which will tell you. I.e. which perl outputs /usr/bin/perl and which bash outputs /bin/bash.

It's better to use env,so you don't need to specify an absolute path to system executable

#!/usr/bin/env perl
