crontab執行腳本得到錯誤的結果,但手動執行可得到正確結果,為何呢?

腳本如下:

#!/bin/sh
#

machineInit()
{
    env_file=/tmp/env_$$
    csh -f <<ENDOFCSH

    source /usr1/amat/current_rls/bin/machine.init
    printenv | /bin/sed 's/\([0-9a-zA-Z_]*\)=\(.*\)$/\1="\2"; export \1/' > $env_file

ENDOFCSH
    echo "env_file=$env_file" >> $env_file
    echo  >> $env_file
    . $env_file
    rm -f $env_file
}

如果我手動執行這個腳本,可得到正確的LOG檔如0929.vdc
但使用crontab 排程執行後卻只能得到沒內容的0929.vdc (僅有檔案無內容)

請問這是什麼原因?
該如何修正?

写脚本要环境变量啊～～～这个问题整个论坛至少问了100遍，100遍

真的很抱歉啊..
小弟是新手..
這腳本也不是小弟寫的..只是工作上遇到一些問題..

可否詳細告知環境變量如何設置呢?
