You can also write:

FILE_LIST[${#FILE_LIST[@]}]="${NEW_FILE}"

This += syntax appears not to work with my version of bash
("4.1.5(1)-release" from package bash 4.1-3). Instead I have
to do this:

BK_LIST+=("${PARAM}")

Was yours a typo, or is it something that now works in yet newer
versions of the shell?

Curious,
Chris

Sigh. Sorry, it was a typo. That explains why it did not work for the OP.
I though that was strange, since I've successfully used arrays to maintain
argument vectors with arguments containing spaces. I was so sure it worked
that I focussed on testing the wrong part.

Phew!

These array things are new to me in a shell context - I've used
associative and indexed arrays for years in awk and perl, though - and
after your example didn't work I went digging through the man page.

I missed it the first time I read the paragraph, but then twigged the
explicit use of the word "compound" in the relevant sentence: "When +=
is applied to an array variable using compound assignment (see Arrays
below) ... new values are appended to the array ...". Digging further
I found that "compound" referred to a list assignment such as X=($Y $Z).

Regards,
Chris
