It appears you pasted some text into the terminal by accident. Since the text you copied contained carriage returns, commands were executed. I see no reason to think anything bad is happening here.
It looks like the text you pasted was, or was very similar to:

This is an initscript to run a Minecraft or CraftBukkit server on ... CraftBukkit (pid 9037) is running. .... ERROR: Process ID list syntax error.
The output error messages you got are mostly consistent with this input. To the extent to which they are not, I suspect some characters just didn't copy and paste correctly, or that there is a discrepancy between what appeared in your Terminal window and what you were able to put into your post. I also improved the formatting in your post but perhaps I made a mistake; that could also account for the discrepancy.
I am not worried. Unless you have additional information to suggest a problem, I wouldn't recommend you be concerned either.
Here's what all your error messages mean:
bash: syntax error near unexpected token `>'
> operator redirects the output of the command on the left to the file specified on the right. But you have more than one of these, separated from each other with spaces (so you're not making the
>> operator, for instance.) That is a syntax error.
> can only be followed by a valid filename.
[ADMIN]: command not found
You ran a string as a command that contained the
| operator. This runs the command to the left of it, and sends (pipes) its output to be the input of the command on the right. The first word of the command on the left was
[ADMIN], so it was interpreted as the name of the command and everything following it was interpreted as command-line arguments to that command.
But there is no
[ADMIN] command--no shell builtin, shell alias, shell function, or program by that name. Therefore, that command was not found and could not be run.
Bukkit: command not found
This is the same situation, just on the right-hand side of the
forums.bukkit.org: command not found
You ran a command where the first word (i.e., before the first space) was
Bukkit, there is no command called
ucd@ucd-uc:~$ 30 posts - 6 authors - Feb 19, 2012 30: command not found
I'm not entirely sure what's going on here. The error message appears on a line where a command was entered, which is unusual, though it sometimes happens when a program runs and produces strange output (output without the expected carriage returns, or output produced after the program has already returned control of the terminal to the shell that invoked it.
But it's not unexpected to see another
command not found error, from text that isn't commands randomly being pasted into the terminal.
bash: syntax error near unexpected token `('
The line you ran contained a leading parenthesis (and a closing one, too, but the shell never got far enough to parse that) under circumstances that didn't make sense to the shell. Parentheses are used to group commands, and the syntax you gave is inconsistent with that use.
ucd@ucd-uc:~$ Getting the process ID in a shell script
This is not output at all. This is just the last line you pasted. Since it's the last line, no carriage return was pasted. So this is just the text you pasted, on a prompt. You can press Ctrl+C to get rid of it.
