在bash脚本中杀死进程

Question

I would like to kill and restart a process and this command works on interactive mode but not in script mode.

Any suggestion:

echo "Killing the running server"
kill $(ps -a | grep 'myserver.jar' | awk '{print $2}') ||  echo 'No active myserver' ; exit 1;

Answer 1

This may work:

v=$(pgrep -f myserver.jar)
if [ $? == 0 ]; then
    kill $v
else 
    echo "no server"
fi
# start server...

Answer 2

When a command runs fine in interactive and not in [ batch, crontab, ... take your own ], you should double check :

• you are using same shell (and not eg bash in interactive and bourne shell in batch)
• you have same PATH

If it's not enough look at all environment variables ...

Answer 3

也许考虑尝试pkill ：

pkill myserver.jar
