I have been searching everywhere for an answer to this question. I have an array in my shell script, but when I run it, I get this error: "(" unexpected
What am I doing wrong here:
array=( 1 2 3 4 5 )
I am using Ubuntu 11.10

You are running your script with /bin/sh, not /bin/bash. There are no arrays in sh.
choroba@cyan ~$ /bin/sh
$ a=( 1 2 3 )
/bin/sh: Syntax error: "(" unexpected

are you using bash?
$ bash --version
GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin11)

$ array=( 1 2 3 4 5 )
$ echo ${array[1]}

Yes, this works fine. However, the script isn't running for some reason.

Weird... When I copy paste entire script into terminal, it works. Why doesn't work as an external file?

@user1068559 you can try running the script with sh --verbose -x script.sh and see where it actually breaks tldp.org/LDP/abs/html/arrays.html might help you as well

Hmm... not revealing much unfortunately. I know the script works, so it must be some kind of quirk with something else.
Also sometime it's because of extra space:
array = (1 2 3 4)
is not right. It should be:
array=(1 2 3 4)

Try specifying the word bash when running the script as follows:
$ bash script.sh
