Bash 命令未找到错误

为什么以下脚本会出现以下错误：

./check1.sh: line 10: Hi,: command not found  
./check1.sh: line 21: syntax error: unexpected end of file

检查1.sh：

#!/bin/bash


subj="host `hostname`"
healthcheckstatus=$(curl -s -o /dev/null -w '%{http_code}' http://localhost)

body="Hi, Application is up"
body1="Hi, Application is down"

mailbody=$([ "$applicationstatus" == 200 ] && $body || $body1)


if [ $healthcheckstatus != "200" ]
then
mail -s "$subj" [email protected] <<EOS
`echo -e $mailbody`
EOS
fi
echo "email subject ::$subj"
echo "email body ::$mailbody"

答案1

线路分配mailbody错误。您正在将$body和/或 的内容$body1作为 shell 命令行进行调用。

代替

mailbody=$([ "$applicationstatus" == 200 ] && $body || $body1)

和

[ "$applicationstatus" = 200 ] && mailbody="$body" || mailbody="$body1"
