I've refined the filesystem size using awk and directed to a file name.
eg, here's the content in a file called "numbers"
$cat numbers
345
543
23423456
44435
546
.
.
how do you write a script to all these numbers to get the total?
thanks a lot. (9 Replies)
Hi, I was wondering if someone could help with what is probably a fairly easy problem. I have two variables, i is between 1-5, j is between 11-15
I'd like to produce this:
1_11
2_12
3_13
4_14
5_15
Each number goes up incrementally with the other.
But my shoddy code is not... (5 Replies)

Hi ,
I am having a scenario where I need to split the file based on two field values. The file is a fixed length file.
ex:

io::async::signal
IO::Async::Signal(3pm) User Contributed Perl Documentation IO::Async::Signal(3pm)NAME
"IO::Async::Signal" - event callback on receipt of a POSIX signal
SYNOPSIS
use IO::Async::Signal;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $signal = IO::Async::Signal->new(
name => "HUP",
on_receipt => sub {
print "I caught SIGHUP
";
},
);
$loop->add( $signal );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a particular POSIX signal is received.
Multiple objects can be added to a "Loop" that all watch for the same signal. The callback functions will all be invoked, in no particular
order.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_receipt
Invoked when the signal is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
name => STRING
The name of the signal to watch. This should be a bare name like "TERM". Can only be given at construction time.
on_receipt => CODE
CODE reference for the "on_receipt" event.
Once constructed, the "Signal" will need to be added to the "Loop" before it will work.
