List of Java processes

Question

How can I list all Java processes in bash? I need an command line. I know there is command ps but I don\'t know what parameters I need to use.

Answer 1

ps axuwww | grep java | grep -v grep

The above will

• show you all processes with long lines (arg: www)
• filter (grep) only lines what contain the word java, and
• filter out the line "grep java" :)

(btw, this example is not the effective one, but simple to remember) ;)

you can pipe the above to another commands, for example:

ps axuwww | grep java | grep -v grep | sed '.....'  | while read something
do
    something_another $something
done

etc...
