thank you for the help and the explanation!
@Franklin52
your solution worked but I am not sure if it works if the computer has been on for more than 24 hours because then the string changes because the days are being added. So I will have to wait for a couple more hours to test your solution.
For now I am using this command
uptime | sed 's/.*up \(.*\),.*user.*/\1/' | awk '{sub(":", "h ", $0); sub(" ", "", $0);print "uptime: " $0 "min"}'
again I have to wait until my computer has been on for more than 24 hours to see if everything works fine.
But for now thanks a lot for the help. I will be back in a couple of hours to report whether the commands are working or not.
can someone please test the two commands (if your computer has been on for more than 24hours) I just mentioned in this post and post the outcome in the forum? that would be great because I might habe to restart my Computer so I will have to wait another 24 hours to test.
Update: the two above commands do not work! the first one does not work because the string changes as time advances so one cannot use $1, $2, $3.
the second does not work because it always prints min at the end and if I just started up the computer it prints something like that: x secsmin and x minsmin
So right now I am using this command
uptime | sed 's/.*up \(.*\),.*user.*/\1/' | awk '{sub(":", "h ", $0); sub(" mins", "min", $0); sub(" secs", "sec", $0); print "uptime@mac: " $0}'
It works fine until hours and probably days are displayed. How can I insert "min" after the minutes that are displayed? the "h" works fine because I always replace ":" but I do not know how to solve the problem with the min so it will display it properly at any time, no matter how long my computer has been running for.

uptime
UPTIME(1) User Commands UPTIME(1)
NAME
uptime - Tell how long the system has been running.
SYNOPSIS
uptime [options]
DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are
currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
This is the same information contained in the header line displayed by w(1).
System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable
state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for
disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a
load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.
