That's pretty neat ! (And quite useful to have in the archives too.) Do=20
you know what happens if a given run of OfflineIMAP takes more than 2=20
minutes though ? That's unlikely to happen and I guess that launchd=20
would wait politely for the first one to exit before launching a second=20
one, but it would be nice to be sure of it ...

That got me a little bit worried, as I would tend to kill the process=20
_before_ restarting the daemon (or whatever a launchd thing should be=20
called). I believe you are saved by setting RunAtLoad to false above,=20
but your script looks like it wants to kill offlineimap as soon as it is=20
started ...

BTW, a good replacement for your last line would be the following :

killall -HUP offlineimap

(plus maybe sleeping for a while and killing it more strongly). So I'd=20
rather say

#!/bin/bash
launchctl stop com.khatchadourian.raffi.offlineimap
sleep 2 # Just in case
killall -HUP offlineimap
sleep 2 # Just in case
killall offlineimap
rm -f /Users/raffi/.offlineimap/lock /Users/raffi/.offlineimap/pid
sleep 2 # Just in case
launchctl start com.khatchadourian.raffi.offlineimap

I might be missing something obvious there, though.
