echo命令中的打印数组

Question

如何在侧面回显命令中打印myArray？

declare -a myArray=([0]="AAA" [1]="AAC" [2]="AAG" [3]="AAU" [4]="ACA" [5]="ACC" [6]="ACG" [7]="ACU" [8]="AGA" [9]="AGC" [10]="AGG" [11]="AGU" [12]="AUA" [13]="AUC")

我知道可以用这种方式完成

echo ${myArray[@]}

或

for i in ${myArray[@]}
do
 echo $i
done

我想要像echo这样的单行命令，（如python中的]

echo ${  for i in ${myArray[@]} }  # does not work

Answer 1

考虑printf：

printf '%s\n' "${myArray[@]}"

Answer 2

使用命令替换

echo "$(for i in ${myArray[@]}; do echo $i; done)"

但实际上只是：

printf "%s\n" "${myArray[@]}"

Answer 3

您可以这样操作

for i in ${myArray[@]}; do  echo $i; done
