Expect脚本下不工作的crontab [英] Expect script does not work under crontab

问题描述

我有一个 expect脚本，我需要我的管理节点上运行，每3分钟收集TX / RX使用命令连接到DCX博科SAN交换机每个端口值 #portperfshow＃

每一次我尝试使用的crontab 执行脚本，每3分钟，该脚本不起作用！

我希望脚本启动与＃的/ usr / bin中/期望-f 和我使用的cron下以下语法调用脚本：

  3 * * * *的/ usr / bin中/期望-f /root/portsperfDCX1/collect-all.exp sanswitchhostname
 

然而，当我执行脚本（未在cron下），它按预期工作：

 根＃./collect-all.exp sanswitchhostname
 

作品就好。

请请谁能帮！谢谢你。

脚本收集-all.exp是：

＃！的/ usr / bin中/期望-f＃时间和日期
集天[时间戳-format％D％M％Y]
设定的时间[时间戳-format％H％M]#logging
设置LogDir1/ FPerf / PortsLogs
等超时5
设置IPADDR [lrange $ ARGV 0 0]
集PASSWXXXXXXX
如果{$ IPADDR ==} {
        把用法：其中，script.exp＆GT;＆LT; IP地址＆gt; \\ n
        1号出口
}
产卵SSH管理@ $ IPADDR
预计-re密码
发送$ PASSW \\ R预计-re管理员                LOG_FILE$ LogDir1 / $日portsperfshow- $时间
                发送portperfshow -tx -rx -t 10 \\ R
                预计超时\\ n
                发送\\ 003
                LOG_FILE                送 - 退出\\ R
                关


解决方案

我有同样的问题，但我的脚本是用

最后，我把它用这两条线取代它的工作：

 预计EOF
出口
 

I have an expect script which I need to run every 3 mins on my management node to collect tx/rx values for each port attached to DCX Brocade SAN Switch using the command #portperfshow#

Each time I try to use crontab to execute the script every 3 mins, the script does not work!

My expect script starts with #!/usr/bin/expect -f and I am calling the script using the following syntax under cron:

3 * * * * /usr/bin/expect -f /root/portsperfDCX1/collect-all.exp sanswitchhostname 

However, when I execute the script (not under cron) it works as expected:

root# ./collect-all.exp sanswitchhostname

works just fine.

Please Please can someone help! Thanks.

The script collect-all.exp is:

#!/usr/bin/expect -f

#Time and Date
set day [timestamp -format %d%m%y]
set time [timestamp -format %H%M]

#logging
set LogDir1 "/FPerf/PortsLogs"
et timeout 5
set ipaddr [lrange $argv 0 0]
set passw "XXXXXXX"


if { $ipaddr == "" } {
        puts "Usage: <script.exp> <ip address>\n"
        exit 1
}


spawn ssh admin@$ipaddr
expect -re "password"
send "$passw\r"

expect -re "admin"

                log_file "$LogDir1/$day-portsperfshow-$time"
                send "portperfshow -tx -rx -t 10\r"
                expect timeout "\n"
                send \003
                log_file

                send -- "exit\r"
                close

解决方案

I had the same issue, except that my script was ending with

interact

Finally I got it working by replacing it with these two lines:

expect eof
exit
