I've got almost the same question as here.
I have an array which contains aa ab aa ac aa ad, etc.
Now I want to select all unique elements from this array.
Thought, this would be simple with sort | uniq or with sort -u as they mentioned in that other question, but nothing changed in the array...
The code is:
echo `echo "${ids[@]}" | sort | uniq`
What am I doing wrong?
