Hi all,
I am new to this list (and new to AIX, new to shell scripts ....) so please
bear with me.
My intention is to provide our operators with a simple, telnet based tool
that allows them to start/stop some subsystems and to watch these
subsystems' logs continuously. And: as an exercise for myself I want to do
it all with shell scripts.
So basically the logic is:
do while true
echo selection screen
read user_selection
case "$user_selection" in
x) tail -f my_log_file
.....
esac
....
done
According to the man(ual) and some tests 'tail -f' can only be ended by
pressing ctrl-c.
This also cancels my shell script which is not the desired effect. (I
experimented with the trap command but to no avail). Any idea how I can
limit ctrl-c to just the 'tail -f' command?
Should there be a more appropriate list for this kind of question then
please advise.
Thanks in advance
Robert
