I want to restrict the values in $1 to only those in interval (a+i*c) to (a+j*c).
For those values in that interval, print the output file with the name output_j where j denotes the value in the loop.
Then each output file I would like to open, read and print only $2.
Sorry, it's a bit hard to explain.
Code:
BEGIN {
a = -6.7
b = 7.0
c =0.1
output_j = "junk"
output_j_f = "junk2"
}
{ for (i = 0; i<=(b-a)/c; i++)&&(j = 1; j<=(b-a)/c; j++) $1<=(a+j*c)&&$1>=(a+i*c) FILENAME > output_j }
print $2 output_j > output_j_f
Alternatively, discard the previous and just consider a loop of i = 0 to (7+6.7)/0.1 =137. Over this loop, I want to restrict $1 in interval (a+i*c) to (a+j*c) so essentially (-6.7 to -6.6), (-6.6 to -6.5) ... (6.9 to 7.0)
I want to print the restricted data for each iteration in loop.
Code:
BEGIN {
a = -6.7
b = 7.0
c =0.1
}
{ for (i = 0; i<=(b-a)/c; i++)&&$1<=(a+j*c)&&$1>=(a+i*c) {print $2 FILENAME > output }}

Can somebody give me a cleaner way of writing the following script. I was thinking that I could use a loop in the awk statement. It works fine the way it is but I just want the script to be cleaner.

I am having a problem with awk when I run it with a loop. It works perfectly when I echo a single line from the commandline. For example:
echo 'MFG009 9153852832' | awk '$2 ~ /^0-9]$/{print $2}'
The Awk command above will print field 2 if field 2 matches 10 digits, but when I run the loop... (5 Replies)

io::async::timer::absolute
IO::Async::Timer::Absolute(3pm) User Contributed Perl Documentation IO::Async::Timer::Absolute(3pm)NAME
"IO::Async::Timer::Absolute" - event callback at a fixed future time
SYNOPSIS
use IO::Async::Timer::Absolute;
use POSIX qw( mktime );
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my @time = gmtime;
my $timer = IO::Async::Timer::Absolute->new(
time => mktime( 0, 0, 0, $time[4]+1, $time[5], $time[6] ),
on_expire => sub {
print "It's midnight
";
$loop->stop;
},
);
$loop->add( $timer );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Timer implements one-shot events at a fixed time in the future. The object waits for a given timestamp, and
invokes its callback at that point in the future.
For a "Timer" object that waits for a delay relative to the time it is started, see instead IO::Async::Timer::Countdown.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_expire
Invoked when the timer expires.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
on_expire => CODE
CODE reference for the "on_expire" event.
time => NUM
The epoch time at which the timer will expire.
Once constructed, the timer object will need to be added to the "Loop" before it will work.
Unlike other timers, it does not make sense to "start" this object, because its expiry time is absolute, and not relative to the time it is
started.
