So much easier:

readarray ARRAY < filename 
  • why minus The answer is absolutely correct (for bash 4). I would give the -t option to remove the line feed. - jfs


 index=0 while read line; do array[$index]="$line" index=$(($index+1)) done < filename 


 for ((a=0; a < ${#array[*]}; a++)) do echo "$a: ${array[$a]}" done
