BASH: make an array of all directory names in a directory that DON'T have a certain pattern in the name

Question

I have a directory that contains a bunch of .zip files as well as their unpacked version. I need to get a list of all the directory's and ignore the .zip files. How can I do this?

I am thinking of using grep and ls, but am not sure how to put it together.

Parsing `ls` is fragile and unsafe. See [Pattern Matching](http://www.gnu.org/software/bash/manual/bashref.html#Pattern-Matching) specifically the bottom section about `extglob`. — Etan Reisner, Jul 07 '15 at 19:23
and to store it in an array? would it be myarr=$(ls | grep -v "\.zip")? — farid99, Jul 07 '15 at 19:24
@EtanReisner so how would you do it? Getting the list of filenames I described? — farid99, Jul 07 '15 at 19:24

Get a list of all sub-directories and store it into an array:

shopt -s nullglob
dirs=( */ )

I used this, but then when I tried `echo $dirs` all I got was one out of the many subdirectories in the working directory. – farid99 Jul 07 '15 at 19:32

You need to use `echo "${dirs[@]}"` to list all directories. – anubhava Jul 07 '15 at 19:33

If you can turn on extglob like so:

shopt -s extglob
declare -a files=( !(*.zip) )

See more about bash pattern matching on the Pattern Matching man page.
