Shell script newbie- how to generate service log from shell script
Hi,
I am totally a newbie to any programming languages and I just started an entry level job in an IT company. One of my recent tasks is to create a script that is able to show the log file of linux service (i.e. ntpd service)
lets say, if I run my script ./test.sh, the output should be similar to :
I dont know if I didnt get the right requirement or something, I found a lot of scripts online but none of them worked for my case. One thing that I don't understand is, do I firstly need to have an existing .log file that has all the ntpd service history? I check var/log/ntpstats but there is no log files.
I would really appreciate if anyone could give me some ideas, if you need any clarifications please let me know.
Thanks very much

service(8) System Manager's Manual service(8)NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
