If your question is more specific you need to provide more information. Are you for example only looking to put the entire contents in a variable or are you trying to create an array from a file? The more verbose your question, the more complete answers you'll get.
To populate an array from a file, there's a new (as of bash 4.0) mapfile built-in (a.k.a. readarray). Each line from stdin will be stored in a separate array element.
Code:
mapfile -t arrayname <file
The -t option removes the trailing newline from the entry, something you'll usually want to do.
For older shell versions you can use something like this:
Code:
while read line ; do
arrayname+=( $line )
done <file

Yeah, I'm using bash, and these little things are a bit confusing to me at first, with what the spaces between equals signs counting and all that. Sweet, thanks for all the help!
