Always no quotes for $() statement. We don't need quotes to hold blanks in result: # i=$(echo 1 2 3) # echo $i 1 2 3 # These quotes can make something wrong in some case: # i=$(echo '!') # # i="$(echo '!')" -bash: !: event not found # No real problem for current code, only to use a better code style.
