SNMP "exec format error" when trying to run a script
提问by wolf2600
I'm using SNMPD to run a script on a Raspberry Pi with net-snmp. I was able to get the same script running on my Slackware machine, but on the Pi, under extOutput.1, I'm getting "Exec format error".
我正在使用 SNMPD 在带有 net-snmp 的 Raspberry Pi 上运行脚本。我能够在我的 Slackware 机器上运行相同的脚本，但是在 Pi 上，在 extOutput.1 下，我收到“Exec 格式错误”。
The batch file being called is set to 777 and is:
被调用的批处理文件设置为 777 并且是：
#! /bin/bash
/sbin/reboot
Everything I've found about the error says that I would just need to include the #! at the beginning of the file and that would fix it, but it doesn't. I can run the script from the command prompt just fine, and /bin/bash obviously works also, but when called through SNMP (both snmpget and snmpwalk), the extOutput.1 line gives me that error.
我发现的关于错误的所有内容都表明我只需要包含 #! 在文件的开头，这会修复它，但它没有。我可以从命令提示符运行脚本就好了，而且 /bin/bash 显然也可以工作，但是当通过 SNMP（snmpget 和 snmpwalk）调用时，extOutput.1 行给了我那个错误。

Ugh. I had a blank line at the top of the script before the #! line.
啊。我在#! 之前的脚本顶部有一个空行。线。
