So I've got a program that allows the user to edit a file either in gedit or using vim. I want a log to update only once the user has finished editing the file. Figured easiest way to do this would be only to update once the user had closed the editor. Been playing around with it for a while now - think I have found the best solution for what I want to do however I can't seem to get it to work.
My code:
(For the vim option the code is identical except 'vim' replaces 'gedit')
My logic is that this will guarantee that the process is terminated before updating the log.. however in practice it just immediately updates the log. Have absolutely no idea what I'm doing wrong! The $PID variable is being filled correctly as I've tested by printing it. Does the PID for a process change and this is why it's not working? Or is my wait command incorrect? When I put an
command after the wait there are no errors in the terminal.

msvc
msvc(8) System Manager's Manual msvc(8)NAME
msvc - control minit
SYNOPSIS
msvc [ -[uodpchaitko] ] [ -P pid ] service [...]
DESCRIPTION
msvc is the management interface to minit. service is the service directory name relative to /etc/minit. Starting with minit 0.9 you can
also include /etc/minit/ in the service name.
OPTIONS
If no option is given, msvc will just print a small diagnostic message to stdout, saying if the service is up, down or finished, which PID
it has if it is up, and for how long it has been in this state.
-u Up. If the service is not running, start it. If the service stops, restart it.
-o Once. If the service is not running, start it. If the service stops, do not restart it.
-d Down. If the service is running, send it a TERM signal and then a CONT signal. After it stops, do not restart it.
-p Pause. Send the service a STOP signal.
-c Continue. Send the service a CONT signal.
-h Hangup. Send the service a HUP signal.
-a Alarm. Send the service an ALRM signal.
-i Interrupt. Send the service an INT signal.
-t Terminate. Send the service a TERM signal.
-k Terminate. Send the service a KILL signal.
-P pid
Set PID. Tell minit the PID of the service is really pid. This is useful for services that fork themselves in the background but put
their real PID in a file, typically called /var/run/service.pid. Used by pidfilehack.
-D service
Print dependencies. This will print all the names of all the services that were started because this services depended on them.
Please note that this is not done recursively (i.e. if default depends on qmail and qmail depends on log, this will print qmail, not
qmail/log. But msvc -D qmail will print qmail/log).
-H Print history. This will print the names of the ten least recently spawned processes. This is useful if you see a process looping
(initialization fails and minit is restarting it all the time).
RETURN CODES
Generally, msvc return zero if everything is OK or 1 on error (could not open /lib/minit/in or /lib/minit/out or there is no process with
the given name). In diagnostic mode, it will exit 0 if the service is up, 2 if it is down or 3 if it is finished.
