在bash的情况下找不到错误命令

Question

我用案例写了bash脚本，当我按照./myscript.sh us-west-1d运行它时会导致错误

./myscript.sh: line 26:  : command not found
./myscript.sh: line 27:  : command not found
./myscript.sh: line 28:  : command not found
ami-fce3c696 us-east-1

但是，当我运行./myscript.sh us-west-1b时，它会正常运行

任何人都可以告诉我如何解决这个问题吗？

#! /bin/bash
AZ=$1
case $AZ in
      us-east-1b)
              SUBNET="subnet-2a3b5d47"
              SECURITY_GROUP=sg-f7d52998
              INVENTORY_GROUP=collector-use1
              WEIGHT=100
              AMI=ami-fce3c696
              REGION=us-east-1
              ;;
      us-east-1d)
              SUBNET="subnet-e6385e8b"
              SECURITY_GROUP=sg-f7d52998
              INVENTORY_GROUP=collector-use1
              WEIGHT=100
              AMI=ami-fce3c696
              REGION=us-east-1
              ;;
      us-east-1e)
              SUBNET="subnet-07395f6a"
              SECURITY_GROUP=sg-f7d52998
              INVENTORY_GROUP=collector-use1
              WEIGHT=100
              AMI=ami-fce3c696
              REGION=us-east-1
              ;;
esac
echo $SUBNET $SECURITY_GROUP $INVENTORY_GROUP $AMI $REGION

我将space替换为tab代表我的案例中的所有行，结果表明它完美无缺。谢谢大家的帮助
