Re: [Evolution] Determining from a Shell script whever evolution is running

I may be wrong, but IMHO you need oaf-slay only once, if you want the
same language-setting every time. oaf-slay killed some processes which
still had the old env variables.

% /sbin/pidof evolution

will answer with the current pid(s) of running evolution, if any. It
even will return a pid, if there is a running evolution for another
user. That means, you get a false positive, if another user is running
evolution remotely. If you are totally sure, this does not happen, you
can use it:

% /sbin/pidof evolution || oaf-slay


If you cannot execute pidof as user or want to make sure the running
evolution belongs to you, you can use:

% ps w -u `id -u` | grep `which evolution` || oaf-slay

Notes:
- The parameter 'w' should not be necessary if executed in a script.
- Commands in backticks ` are executed and substituted by their return
values. This should be safe for all users. Of course you can hardcode
your username (or userid) and /usr/bin/evolution if you are sure they
will never change.


Both commands only will execute oaf-slay if evolution is not running.

If you have questions, feel free to ask or read the man-pages. ;-)
