脚本如下：
#!/bin/sh -x
characters()
{
  read_only=$1
  read_only=`echo $1|awk '{if ($1 ~/[^a-zA-Z]/) print "1"}'
  if [ "$read_only" != "" ]
  then
     return 1
  else
     return 0
  fi
}

echo "enter name"
read name
echo $1
if characters $name
then
   echo "error"
else
   echo "ok"
fi
运行提示： 用法在线23: `文件结束' 非期望的
