I'm using a `while(1)` loop to dispaly real-time information about various files on my system, and I use ^C to exit it when needed. I was hoping there was a way to exit the script on a normal keystroke such as "q". Can someone point me in the right direction? I'm willing to use a... (7 Replies)
i wrote a while script as part of a huge program. this script, once picked, begins to output data to the person using it. pretty easy, as the person doesn't have to keep typing commands to get the output that the while loop automatically throws out.
now, the thing is, while this while-script... (3 Replies)

Hi guys,
I'm new to unix but loving it!! BUT this is driving me nuts as i can't work out the best way to do it.
I have a while true loop that i use to monitor something. For my own reasons in ths script i have disabled the CTRL C using the trap command. But i want to put in a option to exit... (5 Replies)
im running a while loop as a file watcher, with incremental counter on the retries..however when the retries reach it's limit i want it exit and echo and error and stop the batch. Im not sure the code i have will do that already...

I am trying to get my program to exit when the answer to my question is positive, if I am asking if the answers are correct in the entries that the user inputted and the user says no how do I then have it exit? If they say everything is correct then it continue into the program, I think I am close... (2 Replies)

Hi Folks -
Here is a for loop I've created and I just wanted to see if this was okay practice:
for M in NAME1 NAME1 NAME3
do
echo "Executing MaxL:" $M >>${_LOGFILE} 2>&1
. ${_STARTMAXLPATH}startmaxl.sh ${_MAINPATH}${_MAXLPATH}$M.mxl
_RC=$?
if

io::async::timer::periodic
IO::Async::Timer::Periodic(3pm) User Contributed Perl Documentation IO::Async::Timer::Periodic(3pm)NAME
"IO::Async::Timer::Periodic" - event callback at regular intervals
SYNOPSIS
use IO::Async::Timer::Periodic;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $timer = IO::Async::Timer::Periodic->new(
interval => 60,
on_tick => sub {
print "You've had a minute
";
},
);
$timer->start;
$loop->add( $timer );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Timer implements repeating events at regular clock intervals. The timing may or may not be subject to how long
it takes the callback to execute. Iterations may be rescheduled runs at fixed regular intervals beginning at the time the timer was
started, or by a fixed delay after the previous code has finished executing.
For a "Timer" object that only runs a callback once, after a given delay, see instead IO::Async::Timer::Countdown. A Countdown timer can
also be used to create repeating events that fire at a fixed delay after the previous event has finished processing. See als the examples
in "IO::Async::Timer::Countdown".
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_tick
Invoked on each interval of the timer.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
on_tick => CODE
CODE reference for the "on_tick" event.
interval => NUM
The interval in seconds between invocations of the callback or method. Cannot be changed if the timer is running.
first_interval => NUM
Optional. If defined, the interval in seconds after calling the "start" method before the first invocation of the callback or
method. Thereafter, the regular "interval" will be used. If not supplied, the first interval will be the same as the others.
Even if this value is zero, the first invocation will be made asynchronously, by the containing "Loop" object, and not
synchronously by the "start" method itself.
reschedule => STRING
Optional. Must be one of "hard", "skip" or "drift". Defines the algorithm used to reschedule the next invocation.
"hard" schedules each iteration at the fixed interval from the previous iteration's schedule time, ensuring a regular repeating
event.
"skip" schedules similarly to "hard", but skips over times that have already passed. This matters if the duration is particularly
short and there's a possibility that times may be missed, or if the entire process is stopped and resumed by "SIGSTOP" or similar.
"drift" schedules each iteration at the fixed interval from the time that the previous iteration's event handler returns. This
allows it to slowly drift over time and become desynchronised with other events of the same interval or multiples/fractions of it.
Once constructed, the timer object will need to be added to the "Loop" before it will work. It will also need to be started by the "start"
method.
