Find a store in a variable the full path of a folder if exist in BASH -

i need obtain full path of folder (if exists) match specific names. there 1 folder matches name. e.g: code must find, if exists, folder these possible names:

/home/user/myfolder /home/user/myfolder_aaa /home/user/myfolder_bbb /home/user/myfolder_ccc 

but it must not match other "similar" folder, like

/home/user/myfolder_xxx 

and if folder exists need save in variable full path matching unwanted cases , not retry full path:

path=`ls /home/user/myfolder*` 

you can use find regex:

find ./home/user -regextype posix-extended -type f -regex '.*/myfolder(_(aaa|bbb|ccc))?$' 

to store results in array (as don't appear have whitespace in these folder names):

arr=() while ifs= read -r f;    arr+=( "$f" ) done < <(find /home/user -regextype posix-extended -type f -regex '.*/myfolder(_(aaa|bbb|ccc))?$' -print0)  # check array contents declare -p arr
