Unfortunately, because this python script is not a "proper" macOS launch daemon, it will not "keep alive", so I still use cron for that. Maybe I'll find a way to fix this later. Maybe I need to move it to LaunchScripts versus LaunchDaemons? Anyway.... think I'll "call it good" on the unix time sync experiment for now... and as we all know....
I am assigned a programming work.It is my first time to use unix.
The task is writing a shell script to interrogate the university Unix operating system to determine the number of "Runnable" processes at any given time.Then append the result,along with a time-stamp,on a log file. Also there are... (1 Reply)

I needed some help in adding a duration (in seconds) to a start time (in hhmmss format) and a start date (in mmddyy format) in order to get an end date and end time. The concept of a leap year is also to be considered while incrementing the day. The code/ function that I have formed so far is as... (3 Replies)

launchd
launchd(8) BSD System Manager's Manual launchd(8)NAME
launchd -- System wide and per-user daemon/agent manager
SYNOPSIS
launchd [-d] [-D] [-s] [-S SessionType] [-- command [args ...]]
DESCRIPTION
launchd manages processes, both for the system as a whole and for individual users. The primary and preferred interface to launchd is via
the launchctl(1) tool which (among other options) allows the user or administrator to load and unload jobs. Where possible, it is preferable
for jobs to launch on demand based on criteria specified in their respective configuration files.
During boot launchd is invoked by the kernel to run as the first process on the system and to further bootstrap the rest of the system.
You cannot invoke launchd directly.
ENVIRONMENTAL VARIABLES
LAUNCHD_SOCKET
This variable is exported when invoking a command via the launchd command line. It informs launchctl how to find the correct launchd
to talk to.
NOTES
In Darwin, the canonical way to launch a daemon is through launchd as opposed to more traditional mechanisms or mechanisms provided in ear-
lier versions of Mac OS X. These alternate methods should be considered deprecated and not suitable for new projects.
In the launchd lexicon, a "daemon" is, by definition, a system-wide service of which there is one instance for all clients. An "agent" is a
service that runs on a per-user basis. Daemons should not attempt to display UI or interact directly with a user's login session. Any and all
work that involves interacting with a user should be done through agents.
If you wish your service to run as a certain user, in that user's environment, making it a launchd agent is the ONLY supported means of
accomplishing this on Mac OS X. In other words, it is not sufficient to perform a setuid(2) to become a user in the truest sense on Mac OS X.
FILES
~/Library/LaunchAgents Per-user agents provided by the user.
/Library/LaunchAgents Per-user agents provided by the administrator.
/Library/LaunchDaemons System-wide daemons provided by the administrator.
/System/Library/LaunchAgents Per-user agents provided by Mac OS X.
/System/Library/LaunchDaemons System-wide daemons provided by Mac OS X.
