How can I find out the pid of a running equinox instance, is there a pid file?

How can I find out the pid of a running equinox instance, is there a pid file somewhere or is it configura开发者_运维问答ble where it places a pid file?

UPDATE: to make it clear, I have a bunch of instances running, and they are configured roughly the same, so any user only looking for equinox will not know which instance is which

Just execute the following command from CLI:

ps aux | grep equinox

[EDIT] Does equinox bind to some port? If so, for multiple instances you can recognize the one you are interested in basis on port to which it is bound:

sudo netstat -npa |grep equinox

No, Equinox does not create a PID file or report its PID.

You could write a bundle that does this for you, but be aware that there is no standard way for a Java program to retrieve its PID (because some target operating systems don't even have the concept of "PID"). See this post for some ideas.

$ pidof equinox

From the man page:

PIDOF(8) Linux System Administrator's Manual PIDOF(8)

NAME pidof -- find the process ID of a running program.

SYNOPSIS pidof [-s] [-c] [-x] [-o omitpid] [-o omitpid..] program [program..]

DESCRIPTION Pidof finds the process id's (pids) of the named programs. It prints those id's on the standard output. This program is on some systems used in run-level change scripts, especially when the system has a System-V like rc structure. In that case these scripts are located in /etc/rc?.d, where ? is the runlevel. If the system has a start-stop- daemon (8) program that should be used instead.

OPTIONS

-s Single shot - this instructs the program to only return one pid.

-c Only return process ids that are running with the same root directory. This option is ignored for non-root users, as they will be unable to check the current root directory of processes they do not own.

-x Scripts too - this causes the program to also return process id's of shells running the named scripts.

-o omitpid Tells pidof to omit processes with that process id. The special pid %PPID can be used to name the parent process of the pidof program, in other words the calling shell or shell script.

EXIT STATUS

0 At least one program was found with the requested name.

1 No program was found with the requested name.
