shell 内容
#!/bin/bash
i=0
array=()
cat test.txt | while read -r line
do
echo "line="$line
array[$i]="$line"
echo "array[$i] = ${array[$i]}"
i=expr $i + 1
done
echo "array number = ${#array[@]}"
echo ${array[@]}
for var in ${array[@]};
do
echo "var="$var
done
执行shell后返回结果如下：
moonspirit@ubuntu:~/script$ ./test.sh
line=1
array[0] = 1
line=2
array[1] = 2
line=3
array[2] = 3
line=4
array[3] = 4
line=5
array[4] = 5
array number = 0
请问为什么var打印不出之前赋值的类容？
