[dacp1][/export/home]#./aix_xunjian.sh

ksh: ./aix_xunjian.sh:not found.

网上查了资料，说是环境变量的原因。

dacp1][/]#env

发现SHELL对应的变量为/usr/bin/ksh，而我写的脚本却是#！/bin/ksh

至此找的了问题所在！

我在系统用vi把#!/bin/ksh更改为#!/usr/bin/ksh

重新执行#./aix_xunjian.sh发现问题还是发生，not found.

我在本地把脚本更改过之后，重新上传到服务器上执行，问题解决。

疑问:为什么用VI更改过后没用作用呢？

附：#! /bin/ksh
