请教一个Shell脚本问题，command not found错误，求大神

[surging.dandelion]

脚本如下：
#!/bin/bash
progress_name=(
"jboss-desktopd"
"jboss-xxzx"
)
echo "===========check service start==============="
count=0
for loop in ${progress_name[@]}
do
service $loop status>tmp.command
$stdout= "cat tmp.command|grep 'is running'"
if [ -n "$stdout" ]
then
echo "had"
else
echo "no had"
fi
done
echo "===========check service end==============="

第十一行报错，也就是红色字体那段报错，请大神指教

按照一楼的修改之后，还是报一样的问题，没有解决@csdn_vieri

[csdn_vieri]

stdout=`cat tmp.command | grep "is running"`

[csdn_vieri]

$stdout=`cat tmp.command | grep "is running"`

用反引号，等号前后不要空格。

不应该是jboss-desktopd的问题吗？
