Hi,

the output from ps -ef | grep my.jar is:

root 2343 1 0 Jul27 ? 00:00:00
/usr/java/jdk1.5.0_06/bin/java -classpath /usr/local/my.jar: com.Server
/usr/local/logger.property
root 4194 2969 0 01:36 pts/1 00:00:00 grep my.jar

I'm wondering, how to get the 2343 and how to know no such program
running?

I'v tried ps -ef | grep my.jar | cut -f1,2,3 -d' ' but it output:

Remove multiple spaces:

ps -ef | grep '[m]y.jar' | tr -s ' ' | cut -f1,2,3 -d' '

Also, most modern versions of ps allow you to select which fields
you want printed:

ps -eo user,pid,gid,comm | grep '[m]y.jar'

root
root


Toronto

Ditto.
