Bash capturing output of awk into array

Add additional parentheses, like this:

myarr=($(ps -u kdride | awk '{ print $1 }'))

# Now access elements of an array (change "1" to whatever you want)
echo ${myarr[1]}

# Or loop through every element in the array
for i in "${myarr[@]}"
do
   :
  echo $i
done
