在意外的令牌“fi”-高负载通知邮件中出现语法错误。

Im trying to get the server to email me if the load goes above 15, but i keep getting the following error.

如果负载超过15，我试图让服务器给我发邮件，但是我一直有以下错误。

root@echo [~]# sh load.sh
load.sh: line 9: syntax error near unexpected token `fi'
load.sh: line 9: `fi'

Here is the load.sh

这是load.sh

#!/bin/bash
SUBJECT="`hostname`server load is high"
TO=[e-mail]
uptime > /tmp/load
if [ `uptime | awk '{ print$11 }' | cut -d. -f1` -gt 1 ];
then
mail -s "$SUBJECT" $TO < /tmp/load
exit
fi

Server uname -a

服务器uname -

I don't really get the same error than you but you can already test this solution:

我没有得到和你一样的错误但是你已经可以测试这个解了

if [ `uptime | awk '{ print$11 }' | cut -d. -f1` -gt 1 ];

This condition try to compare a float with an integer. I would make this test with an extended test command. And you can forget semicolon if you don't put then keyword on the same line than your condition :

此条件尝试将浮点数与整数进行比较。我将通过一个扩展的测试命令来进行这个测试。你可以忘记分号如果你不把关键字放在同一行上

if [[ `uptime | awk '{ print$11 }' | cut -d. -f1` > 1 ]]
then
   mail -s "$SUBJECT" $TO < /tmp/load
   exit
fi
