我有剧本。它检查系统中是否正在运行某些Java进程，并显示运行时间和JMX端口号。如果我执行所有这些命令，只需在shell中键入它们-一切正常。但是，当我运行此脚本时，会出现错误。请帮助我。
for ADDR in $(cat servers.list)
do
ssh -tt $ADDR << EOF
IFS=$'\n'
for JAVAPS in $(ps ax|grep java|grep -v grep|grep -v javaps.sh|cut -d' ' -f3)
do
RUNTIME=$(ps -o etimes= -p $JAVAPS)
printf -v TIME '%d % 02d % 02d' `expr $RUNTIME / 3600` `expr $RUNTIME / 60 % 60` `expr $RUNTIME % 60`
echo 'Java application has been restarted ' $TIME ' ago.'
if [[echo $JAVAPS|grep jmxremote.port]]
then
JMXPORT=$(echo $JAVAPS|grep -oP '(?<=jmxremote.port=)(\S+)')
echo 'Jmx port=' $JMXPORT
fi
done
exit
EOF
done
这是我得到的：

Try 'ps --help <simple|list|output|threads|misc|all>'

我ve tried to call script on remote node like this from another script file:
for ADDR in $(cat servers.list)
do
ssh -tt $ADDR 'bash -s' < java.sh`
并这样：
for ADDR in $(cat servers.list)
do
ssh -tt $ADDR "......code...... "
它也不起作用。怎么了？
