crontab里tar老是无法运行，请高手指教

nw5452

#!/usr/bin/expect -f
set password 123
set date [ clock format [ clock scan yesterday ] -format "%Y%m%d" ]
if {[ file isdirectory $date ] == 0} exit
spawn /bin/tar -cvzf /usr/sqec/repo/img/detailPage/$date.tar.gz /usr/sqec/repo/img/detailPage/$date
set timeout 18000
spawn /usr/bin/scp $date.tar.gz root@10.10.10.11:/bak_img/img_15/detailPage
expect "root@10.10.10.11's password:"
send "$password\r"
send "exit\r"
expect eof

这个脚本是备份昨天的数据，先要判断下昨天是否生成了目录名为日期的文件夹，然后打包，再scp至其他服务器。

但这个脚本我单独执行是没有问题的，放到crontab里就不行，要么不运行，本地不生成date.tar.gz，但11服务器居然生成了date.tar.gz包，但是该包是空的。

请各位指教。

谢谢。

有没有可能是环境变量的问题，crontab执行定时任务和手动执行环境变量是不同的，猜测哈

    但命令和路径我都用的绝对路径，应该不会是环境变量的问题吧。

我可以加入export试试。

没有压缩就传输，有时候不执行。

这的问题是我要加入环境变量吗？

你什么地方写等tar好再scp了？

回复 7# waker


    set date [ clock format [ clock scan yesterday ] -format "%Y%m%d" ]
if {[ file isdirectory $date ] == 0} exit
spawn /bin/tar -cvzf /usr/sqec/repo/img/detailPage/$date.tar.gz /usr/sqec/repo/img/detailPage/$date
set timeout 18000
spawn /usr/bin/scp $date.tar.gz root@10.10.10.11:/bak_img/img_15/detailPage

这样不行吗？请高手指点下。

1.行不行以自己的测试结果为准
2.建议思考下脚本最后一句的作用是什么   

Shell_HAT

tar和scp中间加个expect试试
