先说下我的情况,SHELL脚本如下：

#!/bin/bash i=1; for file in `ls`;do         A[$i]=$file;         ((i++)) done;

使用 sh a.sh出现错误

a.sh: 4: a.sh: A[1]=1: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=a1.txt: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=a2.txt: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=a.sh: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=a.txt: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=b.sh: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=err.txt: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=in.txt: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=m.txt: not found
a.sh: 5: a.sh: i++: not found
a.sh: 4: a.sh: A[1]=rabbitmq: not found
a.sh: 5: a.sh: i++: not found

不一定是你的脚本除了问题，可能使用的bash命令是有问题的，

查看 ll /bin/sh

lrwxrwxrwx 1 root root 4 Nov 3 06:37 /bin/sh -> dash

用的是dash，解决方式，脚本头部已经有了 #!/bin/bash

接下来赋予其可执行权限即可

./a.sh 成功
