意外标记“done”附近出现 BASH 语法错误

Question

这里有什么问题吗？我在接近“完成”时遇到错误。

echo " Writing a program to print even numbers by adding 1 if the number is odd."
for i in {1..10}
do
    d=$(($i % 2))
    if [[$d = 1]]
    then
        $iq=$(($i+1))
        echo "$iq"
done
echo "end"

Answer 1

这应该有效：

#!/bin/bash -

echo " Writing a program to print even numbers by adding 1 if the number is odd."
for i in {1..10}
do
    d=$(($i % 2))
    if [[ $d -eq 1 ]]
    then
    iq=$(($i+1))
    echo "$iq"
    fi
done
echo "end"

插入 a fi，删除$from$iq=...并在 内添加空格[[ ... ]]。
