Hey bakunin,
Many thanks for your reply!
the following is my plan and let me know if anything doesnt make sense :
1. Ideally the script should print out the log file in the following format:
2019-02-26 09:15:00 +1100,Success,ntpd,restart 2019-02-26 09:16:00 +1100,Error,ntpd,other-activity
But if I am really stuck,as long as the "$(success status),$(service name),$(activity)" are in the output then it will still be fine, someone will extend the script later on..
2. and the fields that I want in the log should include, the last three fields are the minimum and the date is optional depending on the complexity:
$(date and time in fixed format), $(success status), $(service name), $(activity)
3. single log vs multiple logs: I shouldve clarified earlier that the only service I need to work on is ntpd. So a single log would be fine for me.
4. I am not sure if it will be more complicated to write a separate error log since I only need to focus on one service which is ntpd.
Let me know if it makes sense to move on to the next step. thanks again for your help!

script
SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-a] [-k] [-q] [-t time] [file [command ...]]
DESCRIPTION
The script utility makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an
interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
If the argument command ... is given, script will run the specified command with an optional argument vector instead of an interactive shell.
Options:
-a Append the output to file or typescript, retaining the prior contents.
-k Log keys sent to program as well as output.
-q Run in quiet mode, omit the start and stop status messages.
-t time Specify time interval between flushing script output file. A value of 0 causes script to flush for every character I/O event. The
default interval is 30 seconds.
The script ends when the forked shell (or command) exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if
ignoreeof is not set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. The script utility works best with commands that do not
manipulate the screen. The results are meant to emulate a hardcopy terminal, not an addressable one.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO
csh(1) (for the history mechanism).
HISTORY
The script command appeared in 3.0BSD.
BUGS
The script utility places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
It is not possible to specify a command without also naming the script file because of argument parsing compatibility issues.
When running in -k mode, echo cancelling is far from ideal. The slave terminal mode is checked for ECHO mode to check when to avoid manual
echo logging. This does not work when in a raw mode where the program being run is doing manual echo.
