You could always experiment with NSTask, running the "ps"
command ... option "w" gives you the full path, I believe. "-auxw"
will give you all processes, including their paths.

Given a path (or FSRef/NSURL/whatever) to an application's

I want to check to see if this executable is running, hopefully in a

different
apps). It would be cool if the same technique worked for command-
line
tools too, but that's not a strict requirement.
Is there a way to accomplish this, using either Cocoa, Carbon or
lower-level Posix calls? (Technically, Posix would be a little
better
fit for us, since we could avoid forking the code. Either way is
fine, though.)
I think you want to look at [[NSWorkspace sharedWorkspace]
launchedApplications]. Then scan the resulting dictionaries for your
path-- in the NSApplicationPath key.
I'm sure it's possible in Carbon, but that's the obvious Cocoa
starting point.
I experimented with -launchedApplications in the past, but it had a
lot of limitations—it only displayed apps that are end-user
visible. Things like faceless apps and command line tools weren't
included.
What does Activity Monitor use? It can even see other users' apps.
That would be ideal for me.
