shell for循环两个变量兑现
shell for循环两个变量实现
我想实现for里面如下代码，可语法错误，有没有类似的实现方式呢
#!/bin/bash
src1=/home/ubuntu/quinton/search/test1
src2=/home/ubuntu/quinton/search/test2
for file hi in $src1 $src2
do
echo here are $file $hi
done
------解决方案--------------------
1 #!/bin/bash
2
3 src1=/home/ubuntu/quinton/search/test1
4 src2=/home/ubuntu/quinton/search/test2
5
6 for file in $src1; do
7
8 echo here are $file
9 done
10 for hi in $src2; do
11
12 echo here are $hi
13 done
分开写，可以的。
